+
+    A Q3IconDrag object is used to maintain information about the
+    positions of dragged items and the data associated with them.
+    Q3IconViews are able to use this information to paint the dragged
+    items in the correct positions. Internally, Q3IconDrag stores the
+    data associated with drag items in Q3IconDragItem objects.
+
+    If you want to use the extended drag and drop functionality of
+    Q3IconView, create a Q3IconDrag object in a reimplementation of
+    Q3IconView::dragObject(). Then create a Q3IconDragItem for each item
+    which should be dragged, set the data it represents with
+    Q3IconDragItem::setData(), and add each Q3IconDragItem to the drag
+    object using append().
+
+    The data in Q3IconDragItems is stored in a QByteArray and is
+    mime-typed (see QMimeSource and the
+    \link http://doc.trolltech.com/dnd.html Drag and Drop\endlink
+    overview). If you want to use your own mime-types derive a class
+    from Q3IconDrag and reimplement format(), encodedData() and
+    canDecode().
+
+    The fileiconview example program demonstrates the use of the

+    \class Q3IconViewItem
+    \brief The Q3IconViewItem class provides a single item in a Q3IconView.
+
+    \compat
+
+    A Q3IconViewItem contains an icon, a string and optionally a sort
+    key, and can display itself in a Q3IconView.
+
+    The simplest way to create a Q3IconViewItem and insert it into a
+    Q3IconView is to construct the item passing the constructor a
+    pointer to the icon view, a string and an icon:
+
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3iconview.cpp 0
+
+    By default the text of an icon view item may not be edited by the
+    user but calling setRenameEnabled(true) will allow the user to
+    perform in-place editing of the item's text.
+
+    When the icon view is deleted all items in it are deleted
+    automatically.
+
+    The Q3IconView::firstItem() and Q3IconViewItem::nextItem() functions
+    provide a means of iterating over all the items in a Q3IconView:
+
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3iconview.cpp 1
+
+    The item's icon view is available from iconView(), and its
+    position in the icon view from index().
+
+    The item's selection status is available from isSelected() and is
+    set and controlled by setSelected() and isSelectable().
+
+    The text and icon can be set with setText() and setPixmap() and
+    retrieved with text() and pixmap(). The item's sort key defaults
+    to text() but may be set with setKey() and retrieved with key().
+    The comparison function, compare() uses key().
+
+    Items may be repositioned with move() and moveBy(). An item's
+    geometry is available from rect(), x(), y(), width(), height(),
+    size(), pos(), textRect() and pixmapRect(). You can also test
+    against the position of a point with contains() and intersects().
+
+    To remove an item from an icon view, just delete the item. The
+    Q3IconViewItem destructor removes it cleanly from its icon view.
+
+    Because the icon view is designed to use drag-and-drop, the icon
+    view item also has functions for drag-and-drop which may be
+    reimplemented.
+
+    The class is designed to be very similar to Q3ListView and Q3ListBox
+    in use, both via instantiation and subclassing.

+    \class Q3IconView
+    \brief The Q3IconView class provides an area with movable labelled icons.
+
+    \compat
+
+    A Q3IconView can display and manage a grid or other 2D layout of
+    labelled icons. Each labelled icon is a Q3IconViewItem. Items
+    (Q3IconViewItems) can be added or deleted at any time; items can be
+    moved within the Q3IconView. Single or multiple items can be
+    selected. Items can be renamed in-place. Q3IconView also supports
+    \link #draganddrop drag and drop\endlink.
+
+    Each item contains a label string, a pixmap or picture (the icon
+    itself) and optionally a sort key. The sort key is used for
+    sorting the items and defaults to the label string. The label
+    string can be displayed below or to the right of the icon (see \l
+    ItemTextPos).
+
+    The simplest way to create a Q3IconView is to create a Q3IconView
+    object and create some Q3IconViewItems with the Q3IconView as their
+    parent, set the icon view's geometry and show it.
+    For example:
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3iconview.cpp 4
+
+    The Q3IconViewItem call passes a pointer to the Q3IconView we wish to
+    populate, along with the label text and a QPixmap.
+
+    When an item is inserted the Q3IconView allocates a position for it.
+    Existing items are rearranged if autoArrange() is true. The
+    default arrangement is \l LeftToRight -- the Q3IconView fills up
+    the \e left-most column from top to bottom, then moves one column
+    \e right and fills that from top to bottom and so on. The
+    arrangement can be modified with any of the following approaches:
+    \list
+    \i Call setArrangement(), e.g. with \l TopToBottom which will fill
+    the \e top-most row from left to right, then moves one row \e down
+    and fills that row from left to right and so on.
+    \i Construct each Q3IconViewItem using a constructor which allows
+    you to specify which item the new one is to follow.
+    \i Call setSorting() or sort() to sort the items.
+    \endlist
+
+    The spacing between items is set with setSpacing(). Items can be
+    laid out using a fixed grid using setGridX() and setGridY(); by
+    default the Q3IconView calculates a grid dynamically. The position
+    of items' label text is set with setItemTextPos(). The text's
+    background can be set with setItemTextBackground(). The maximum
+    width of an item and of its text are set with setMaxItemWidth()
+    and setMaxItemTextLength(). The label text will be word-wrapped if
+    it is too long; this is controlled by setWordWrapIconText(). If
+    the label text is truncated, the user can still see the entire
+    text in a tool tip if they hover the mouse over the item. This is
+    controlled with setShowToolTips().
+
+    Items which are \link Q3IconViewItem::isSelectable()
+    selectable\endlink may be selected depending on the SelectionMode;
+    the default is \l Single. Because Q3IconView offers multiple
+    selection it must display keyboard focus and selection state
+    separately. Therefore there are functions to set the selection
+    state of an item (setSelected()) and to select which item displays
+    keyboard focus (setCurrentItem()). When multiple items may be
+    selected the icon view provides a rubberband, too.
+
+    When in-place renaming is enabled (it is disabled by default), the
+    user may change the item's label. They do this by selecting the item
+    (single clicking it or navigating to it with the arrow keys), then
+    single clicking it (or pressing F2), and entering their text. If no
+    key has been set with Q3IconViewItem::setKey() the new text will also
+    serve as the key. (See Q3IconViewItem::setRenameEnabled().)
+
+    You can control whether users can move items themselves with
+    setItemsMovable().
+
+    Because the internal structure used to store the icon view items is
+    linear, no iterator class is needed to iterate over all the items.
+    Instead we iterate by getting the first item from the \e{icon view}
+    and then each subsequent (\l Q3IconViewItem::nextItem()) from each
+    \e item in turn:
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3iconview.cpp 5
+    Q3IconView also provides currentItem(). You can search for an item
+    using findItem() (searching by position or for label text) and
+    with findFirstVisibleItem() and findLastVisibleItem(). The number
+    of items is returned by count(). An item can be removed from an
+    icon view using takeItem(); to delete an item use \c delete. All
+    the items can be deleted with clear().
+
+    The Q3IconView emits a wide range of useful signals, including
+    selectionChanged(), currentChanged(), clicked(), moved() and
+    itemRenamed().
+
+    \target draganddrop
+    \section1 Drag and Drop
+
+    Q3IconView supports the drag and drop of items within the Q3IconView
+    itself. It also supports the drag and drop of items out of or into
+    the Q3IconView and drag and drop onto items themselves. The drag and
+    drop of items outside the Q3IconView can be achieved in a simple way
+    with basic functionality, or in a more sophisticated way which
+    provides more power and control.
+
+    The simple approach to dragging items out of the icon view is to
+    subclass Q3IconView and reimplement Q3IconView::dragObject().
+
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3iconview.cpp 6
+
+    In this example we create a Q3TextDrag object, (derived from
+    Q3DragObject), containing the item's label and return it as the drag
+    object. We could just as easily have created a Q3ImageDrag from the
+    item's pixmap and returned that instead.
+
+    Q3IconViews and their Q3IconViewItems can also be the targets of drag
+    and drops. To make the Q3IconView itself able to accept drops connect
+    to the dropped() signal. When a drop occurs this signal will be
+    emitted with a QDragEvent and a QLinkedList of Q3IconDragItems. To
+    make a Q3IconViewItem into a drop target subclass Q3IconViewItem and
+    reimplement Q3IconViewItem::acceptDrop() and
+    Q3IconViewItem::dropped().
+
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3iconview.cpp 7
+
+    If you want to use extended drag-and-drop or have drag shapes drawn
+    you must take a more sophisticated approach.
+
+    The first part is starting drags -- you should use a Q3IconDrag (or a
+    class derived from it) for the drag object. In dragObject() create the
+    drag object, populate it with Q3IconDragItems and return it. Normally
+    such a drag should offer each selected item's data. So in dragObject()
+    you should iterate over all the items, and create a Q3IconDragItem for
+    each selected item, and append these items with Q3IconDrag::append() to
+    the Q3IconDrag object. You can use Q3IconDragItem::setData() to set the
+    data of each item that should be dragged. If you want to offer the
+    data in additional mime-types, it's best to use a class derived from
+    Q3IconDrag, which implements additional encoding and decoding
+    functions.
+
+    When a drag enters the icon view, there is little to do. Simply
+    connect to the dropped() signal and reimplement
+    Q3IconViewItem::acceptDrop() and Q3IconViewItem::dropped(). If you've
+    used a Q3IconDrag (or a subclass of it) the second argument to the
+    dropped signal contains a QLinkedList of Q3IconDragItems -- you can
+    access their data by calling Q3IconDragItem::data() on each one.
+
+    For an example implementation of complex drag-and-drop look at the
+    fileiconview example (qt/examples/fileiconview).

+
+/*!
+    \enum Q3IconView::SelectionMode
+
+    This enumerated type is used by Q3IconView to indicate how it
+    reacts to selection by the user. It has four values:
+
+    \value Single  When the user selects an item, any already-selected
+    item becomes unselected and the user cannot unselect the selected
+    item. This means that the user can never clear the selection. (The
+    application programmer can, using Q3IconView::clearSelection().)
+
+    \value Multi  When the user selects an item, e.g. by navigating to
+    it with the keyboard arrow keys or by clicking it, the selection
+    status of that item is toggled and the other items are left alone.
+
+    \value Extended  When the user selects an item the selection is
+    cleared and the new item selected. However, if the user presses
+    the Ctrl key when clicking on an item, the clicked item gets
+    toggled and all other items are left untouched. If the user
+    presses the Shift key while clicking on an item, all items between
+    the current item and the clicked item get selected or unselected,
+    depending on the state of the clicked item. Also, multiple items
+    can be selected by dragging the mouse while the left mouse button
+    stays pressed.
+
+    \value NoSelection  Items cannot be selected.
+
+    To summarize: \c Single is a real single-selection icon view; \c
+    Multi a real multi-selection icon view; \c Extended is an icon
+    view in which users can select multiple items but usually want to
+    select either just one or a range of contiguous items; and \c
+    NoSelection mode is for an icon view where the user can look but

+    \class Q3ListBox
+    \brief The Q3ListBox widget provides a list of selectable, read-only items.
+
+    \compat
+
+    This is typically a single-column list in which either no item or
+    one item is selected, but it can also be used in many other ways.
+
+    Q3ListBox will add scroll bars as necessary, but it isn't intended
+    for \e really big lists. If you want more than a few thousand
+    items, it's probably better to use a different widget mainly
+    because the scroll bars won't provide very good navigation, but
+    also because Q3ListBox may become slow with huge lists. (See
+    Q3ListView and Q3Table for possible alternatives.)
+
+    There are a variety of selection modes described in the
+    Q3ListBox::SelectionMode documentation. The default is \l Single
+    selection mode, but you can change it using setSelectionMode().
+    (setMultiSelection() is still provided for compatibility with Qt
+    1.x. We recommend using setSelectionMode() in all code.)
+
+    Because Q3ListBox offers multiple selection it must display
+    keyboard focus and selection state separately. Therefore there are
+    functions both to set the selection state of an item, i.e.
+    setSelected(), and to set which item displays keyboard focus, i.e.
+    setCurrentItem().
+
+    The list box normally arranges its items in a single column and
+    adds a vertical scroll bar if required. It is possible to have a
+    different fixed number of columns (setColumnMode()), or as many
+    columns as will fit in the list box's assigned screen space
+    (setColumnMode(FitToWidth)), or to have a fixed number of rows
+    (setRowMode()) or as many rows as will fit in the list box's
+    assigned screen space (setRowMode(FitToHeight)). In all these
+    cases Q3ListBox will add scroll bars, as appropriate, in at least
+    one direction.
+
+    If multiple rows are used, each row can be as high as necessary
+    (the normal setting), or you can request that all items will have
+    the same height by calling setVariableHeight(false). The same
+    applies to a column's width, see setVariableWidth().
+
+    The Q3ListBox's items are Q3ListBoxItem objects. Q3ListBox provides
+    methods to insert new items as strings, as pixmaps, and as
+    Q3ListBoxItem * (insertItem() with various arguments), and to
+    replace an existing item with a new string, pixmap or Q3ListBoxItem
+    (changeItem() with various arguments). You can also remove items
+    singly with removeItem() or clear() the entire list box. Note that
+    if you create a Q3ListBoxItem yourself and insert it, Q3ListBox
+    takes ownership of the item.
+
+    You can also create a Q3ListBoxItem, such as Q3ListBoxText or
+    Q3ListBoxPixmap, with the list box as first parameter. The item
+    will then append itself. When you delete an item it is
+    automatically removed from the list box.
+
+    The list of items can be arbitrarily large; Q3ListBox will add
+    scroll bars if necessary. Q3ListBox can display a single-column
+    (the common case) or multiple-columns, and offers both single and
+    multiple selection. Q3ListBox does not support multiple-column
+    items (but Q3ListView and Q3Table do), or tree hierarchies (but
+    Q3ListView does).
+
+    The list box items can be accessed both as Q3ListBoxItem objects
+    (recommended) and using integer indexes (the original Q3ListBox
+    implementation used an array of strings internally, and the API
+    still supports this mode of operation). Everything can be done
+    using the new objects, and most things can be done using indexes.
+
+    Each item in a Q3ListBox contains a Q3ListBoxItem. One of the items
+    can be the current item. The currentChanged() signal and the
+    highlighted() signal are emitted when a new item becomes current,
+    e.g. because the user clicks on it or Q3ListBox::setCurrentItem()
+    is called. The selected() signal is emitted when the user
+    double-clicks on an item or presses Enter on the current item.
+
+    If the user does not select anything, no signals are emitted and
+    currentItem() returns -1.
+
+    A list box has Qt::WheelFocus as a default focusPolicy(), i.e. it
+    can get keyboard focus by tabbing, clicking and through the use of
+    the mouse wheel.
+
+    New items can be inserted using insertItem(), insertStrList() or
+    insertStringList().
+
+    By default, vertical and horizontal scroll bars are added and
+    removed as necessary. setHScrollBarMode() and setVScrollBarMode()
+    can be used to change this policy.
+
+    If you need to insert types other than strings and pixmaps, you
+    must define new classes which inherit Q3ListBoxItem.
+
+    \warning The list box assumes ownership of all list box items and
+    will delete them when it does not need them any more.

+    \enum Q3ListBox::SelectionMode
+
+    This enumerated type is used by Q3ListBox to indicate how it reacts
+    to selection by the user.
+
+    \value Single  When the user selects an item, any already-selected
+    item becomes unselected and the user cannot unselect the selected
+    item. This means that the user can never clear the selection, even
+    though the selection may be cleared by the application programmer
+    using Q3ListBox::clearSelection().
+
+    \value Multi  When the user selects an item the selection status
+    of that item is toggled and the other items are left alone.
+
+    \value Extended When the user selects an item the selection is
+    cleared and the new item selected. However, if the user presses
+    the Ctrl key when clicking on an item, the clicked item gets
+    toggled and all other items are left untouched. And if the user
+    presses the Shift key while clicking on an item, all items between
+    the current item and the clicked item get selected or unselected,
+    depending on the state of the clicked item. Also, multiple items
+    can be selected by dragging the mouse while the left mouse button
+    is kept pressed.
+
+    \value NoSelection  Items cannot be selected.
+
+    In other words, \c Single is a real single-selection list box, \c
+    Multi is a real multi-selection list box, \c Extended is a list
+    box in which users can select multiple items but usually want to
+    select either just one or a range of contiguous items, and \c
+    NoSelection is for a list box where the user can look but not
+    touch.

+    \class Q3ListViewItem
+    \brief The Q3ListViewItem class implements a list view item.
+
+    \compat
+
+    A list view item is a multi-column object capable of displaying
+    itself in a Q3ListView.
+
+    The easiest way to use Q3ListViewItem is to construct one with a
+    few constant strings, and either a Q3ListView or another
+    Q3ListViewItem as parent.
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3listview.cpp 0
+    We've discarded the pointers to the items since we can still access
+    them via their parent \e listView. By default, Q3ListView sorts its
+    items; this can be switched off with Q3ListView::setSorting(-1).
+
+    The parent must be another Q3ListViewItem or a Q3ListView. If the
+    parent is a Q3ListView, the item becomes a top-level item within
+    that Q3ListView. If the parent is another Q3ListViewItem, the item
+    becomes a child of that list view item.
+
+    If you keep the pointer, you can set or change the texts using
+    setText(), add pixmaps using setPixmap(), change its mode using
+    setSelectable(), setSelected(), setOpen() and setExpandable().
+    You'll also be able to change its height using setHeight(), and
+    traverse its sub-items. You don't have to keep the pointer since
+    you can get a pointer to any Q3ListViewItem in a Q3ListView using
+    Q3ListView::selectedItem(), Q3ListView::currentItem(),
+    Q3ListView::firstChild(), Q3ListView::lastItem() and
+    Q3ListView::findItem().
+
+    If you call \c delete on a list view item, it will be deleted as
+    expected, and as usual for \l{QObject}s, if it has any child items
+    (to any depth), all these will be deleted too.
+
+    \l{Q3CheckListItem}s are list view items that have a checkbox or
+    radio button and can be used in place of plain Q3ListViewItems.
+
+    You can traverse the tree as if it were a doubly-linked list using
+    itemAbove() and itemBelow(); they return pointers to the items
+    directly above and below this item on the screen (even if none of
+    them are actually visible at the moment).
+
+    Here's how to traverse all of an item's children (but not its
+    children's children, etc.):
+    Example:
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3listview.cpp 1
+
+    If you want to iterate over every item, to any level of depth use
+    an iterator. To iterate over the entire tree, initialize the
+    iterator with the list view itself; to iterate over an item's
+    children (and children's children to any depth), initialize the
+    iterator with the item:
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3listview.cpp 2
+
+    Note that the order of the children will change when the sorting
+    order changes and is undefined if the items are not visible. You
+    can, however, call enforceSortOrder() at any time; Q3ListView will
+    always call it before it needs to show an item.
+
+    Many programs will need to reimplement Q3ListViewItem. The most
+    commonly reimplemented functions are:
+    \table
+    \header \i Function \i Description
+    \row \i \l text()
+         \i Returns the text in a column. Many subclasses will compute
+            this on the fly.
+    \row \i \l key()
+         \i Used for sorting. The default key() simply calls
+            text(), but judicious use of key() can give you fine
+            control over sorting; for example, QFileDialog
+            reimplements key() to sort by date.
+    \row \i \l setup()
+         \i Called before showing the item and whenever the list
+            view's font changes, for example.
+    \row \i \l activate()
+         \i Called whenever the user clicks on the item or presses
+            Space when the item is the current item.
+    \endtable
+
+    Some subclasses call setExpandable(true) even when they have no
+    children, and populate themselves when setup() or setOpen(true) is
+    called. The \c dirview/dirview.cpp example program uses this
+    technique to start up quickly: The files and subdirectories in a
+    directory aren't inserted into the tree until they're actually
+    needed.

+    \class Q3ListView
+    \brief The Q3ListView class implements a list/tree view.
+
+    \compat
+
+    It can display and control a hierarchy of multi-column items, and
+    provides the ability to add new items at any time. The user may
+    select one or many items (depending on the \c SelectionMode) and
+    sort the list in increasing or decreasing order by any column.
+
+    The simplest pattern of use is to create a Q3ListView, add some
+    column headers using addColumn() and create one or more
+    Q3ListViewItem or Q3CheckListItem objects with the Q3ListView as
+    parent.
+
+    Further nodes can be added to the list view object (the root of the
+    tree) or as child nodes to Q3ListViewItems.
+
+    The main setup functions are:
+    \table
+    \header \i Function \i Action
+    \row \i \l addColumn()
+         \i Adds a column with a text label and perhaps width. Columns
+            are counted from the left starting with column 0.
+    \row \i \l setColumnWidthMode()
+         \i Sets the column to be resized automatically or not.
+    \row \i \l setAllColumnsShowFocus()
+         \i Sets whether items should show keyboard focus using all
+            columns or just column 0. The default is to show focus
+            just using column 0.
+    \row \i \l setRootIsDecorated()
+         \i Sets whether root items can be opened and closed by the
+            user and have open/close decoration to their left. The
+            default is false.
+    \row \i \l setTreeStepSize()
+         \i Sets how many pixels an item's children are indented
+            relative to their parent. The default is 20. This is
+            mostly a matter of taste.
+    \row \i \l setSorting()
+         \i Sets whether the items should be sorted, whether it should
+            be in ascending or descending order, and by what column
+            they should be sorted. By default the list view is sorted
+            by the first column; to switch this off call setSorting(-1).
+    \endtable
+
+    There are several functions for mapping between items and
+    coordinates. itemAt() returns the item at a position on-screen,
+    itemRect() returns the rectangle an item occupies on the screen,
+    and itemPos() returns the position of any item (whether it is
+    on-screen or not). firstChild() returns the list view's first item
+    (not necessarily visible on-screen).
+
+    You can iterate over visible items using
+    Q3ListViewItem::itemBelow(); over a list view's top-level items
+    using Q3ListViewItem::firstChild() and
+    Q3ListViewItem::nextSibling(); or every item using a
+    Q3ListViewItemIterator. See
+    the Q3ListViewItem documentation for examples of traversal.
+
+    An item can be moved amongst its siblings using
+    Q3ListViewItem::moveItem(). To move an item in the hierarchy use
+    takeItem() and insertItem(). Item's (and all their child items)
+    are deleted with \c delete; to delete all the list view's items
+    use clear().
+
+    There are a variety of selection modes described in the
+    Q3ListView::SelectionMode documentation. The default is \c Single
+    selection, which you can change using setSelectionMode().
+
+    Because Q3ListView offers multiple selection it must display
+    keyboard focus and selection state separately. Therefore there are
+    functions both to set the selection state of an item
+    (setSelected()) and to set which item displays keyboard focus
+    (setCurrentItem()).
+
+    Q3ListView emits two groups of signals; one group signals changes
+    in selection/focus state and one indicates selection. The first
+    group consists of selectionChanged() (applicable to all list
+    views), selectionChanged(Q3ListViewItem*) (applicable only to a
+    \c Single selection list view), and currentChanged(Q3ListViewItem*).
+    The second group consists of doubleClicked(Q3ListViewItem*),
+    returnPressed(Q3ListViewItem*),
+    rightButtonClicked(Q3ListViewItem*, const QPoint&, int), etc.
+
+    Note that changing the state of the list view in a slot connected
+    to a list view signal may cause unexpected side effects. If you
+    need to change the list view's state in response to a signal, use
+    a \link QTimer::singleShot() single shot timer\endlink with a
+    time out of 0, and connect this timer to a slot that modifies the
+    list view's state.
+
+    In Motif style, Q3ListView deviates fairly strongly from the look
+    and feel of the Motif hierarchical tree view. This is done mostly
+    to provide a usable keyboard interface and to make the list view
+    look better with a white background.
+
+    If selectionMode() is \c Single (the default) the user can select
+    one item at a time, e.g. by clicking an item with the mouse, see
+    \l Q3ListView::SelectionMode for details.
+
+    The list view can be navigated either using the mouse or the
+    keyboard. Clicking a \bold{-} icon closes an item (hides its
+    children) and clicking a \bold{+} icon opens an item (shows its
+    children). The keyboard controls are these:
+    \table
+    \header \i Keypress \i Action
+    \row \i Home
+         \i Make the first item current and visible.
+    \row \i End
+         \i Make the last item current and visible.
+    \row \i Page Up
+         \i Make the item above the top visible item current and visible.
+    \row \i Page Down
+         \i Make the item below the bottom visible item current and visible.
+    \row \i Up Arrow
+         \i Make the item above the current item current and visible.
+    \row \i Down Arrow
+         \i Make the item below the current item current and visible.
+    \row \i Left Arrow
+         \i If the current item is closed (\bold{+} icon) or has no
+            children, make its parent item current and visible. If the
+            current item is open (\bold{-} icon) close it, i.e. hide its
+            children. Exception: if the current item is the first item
+            and is closed and the horizontal scroll bar is offset to
+            the right the list view will be scrolled left.
+    \row \i Right Arrow
+         \i If the current item is closed (\bold{+} icon) and has
+            children, the item is opened. If the current item is
+            opened (\bold{-} icon) and has children the item's first
+            child is made current and visible. If the current item has
+            no children the list view is scrolled right.
+    \endtable
+
+    If the user starts typing letters with the focus in the list view
+    an incremental search will occur. For example if the user types
+    'd' the current item will change to the first item that begins
+    with the letter 'd'; if they then type 'a', the current item will
+    change to the first item that begins with 'da', and so on. If no
+    item begins with the letters they type the current item doesn't
+    change.
+
+    Note that the list view's size hint is calculated taking into
+    account the height \e and width to produce a nice aspect ratio.
+    This may mean that you need to reimplement sizeHint() in some
+    cases.
+
+    \warning The list view assumes ownership of all list view items
+    and will delete them when it does not need them any more.

+/*!
+    \class Q3ListViewItemIterator
+    \brief The Q3ListViewItemIterator class provides an iterator for collections of Q3ListViewItems.
+
+    \compat
+
+    Construct an instance of a Q3ListViewItemIterator, with either a
+    Q3ListView* or a Q3ListViewItem* as argument, to operate on the tree
+    of Q3ListViewItems, starting from the argument.
+
+    A Q3ListViewItemIterator iterates over all the items from its
+    starting point. This means that it always makes the first child of
+    the current item the new current item. If there is no child, the
+    next sibling becomes the new current item; and if there is no next
+    sibling, the next sibling of the parent becomes current.
+
+    The following example creates a list of all the items that have
+    been selected by the user, storing pointers to the items in a
+    QList:
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3listview.cpp 6
+
+    An alternative approach is to use an \c IteratorFlag:
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3listview.cpp 7
+
+    A Q3ListViewItemIterator provides a convenient and easy way to
+    traverse a hierarchical Q3ListView.
+
+    Multiple Q3ListViewItemIterators can operate on the tree of
+    Q3ListViewItems. A Q3ListView knows about all iterators operating on
+    its Q3ListViewItems. So when a Q3ListViewItem gets removed all
+    iterators that point to this item are updated and point to the
+    following item if possible, otherwise to a valid item before the
+    current one or to 0. Note however that deleting the parent item of
+    an item that an iterator points to is not safe.

+    \class Q3TableSelection
+    \brief The Q3TableSelection class provides access to a selected area in a
+    Q3Table.
+
+    \compat
+
+    The selection is a rectangular set of cells in a Q3Table. One of
+    the rectangle's cells is called the anchor cell; this is the cell
+    that was selected first. The init() function sets the anchor and
+    the selection rectangle to exactly this cell; the expandTo()
+    function expands the selection rectangle to include additional
+    cells.
+
+    There are various access functions to find out about the area:
+    anchorRow() and anchorCol() return the anchor's position;
+    leftCol(), rightCol(), topRow() and bottomRow() return the
+    rectangle's four edges. All four are part of the selection.
+
+    A newly created Q3TableSelection is inactive -- isActive() returns
+    false. You must use init() and expandTo() to activate it.

+    \class Q3TableItem
+    \brief The Q3TableItem class provides the cell content for Q3Table cells.
+
+    \compat
+
+    For many applications Q3TableItems are ideal for presenting and
+    editing the contents of Q3Table cells. In situations where you need
+    to create very large tables you may prefer an alternative approach
+    to using Q3TableItems: see the notes on large tables.
+
+    A Q3TableItem contains a cell's data, by default, a string and a
+    pixmap. The table item also holds the cell's display size and how
+    the data should be aligned. The table item specifies the cell's
+    \l EditType and the editor used for in-place editing (by default a
+    QLineEdit). If you want checkboxes use \l{Q3CheckTableItem}, and if
+    you want comboboxes use \l{Q3ComboTableItem}. The \l EditType (set
+    in the constructor) determines whether the cell's contents may be
+    edited.
+
+    If a pixmap is specified it is displayed to the left of any text.
+    You can change the text or pixmap with setText() and setPixmap()
+    respectively. For text you can use setWordWrap().
+
+    When sorting table items the key() function is used; by default
+    this returns the table item's text(). Reimplement key() to
+    customize how your table items will sort.
+
+    Table items are inserted into a table using Q3Table::setItem(). If
+    you insert an item into a cell that already contains a table item
+    the original item will be deleted.
+
+    Example:
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3table.cpp 0
+
+    You can move a table item from one cell to another, in the same or
+    a different table, using Q3Table::takeItem() and Q3Table::setItem()
+    but see also Q3Table::swapCells().
+
+    Table items can be deleted with delete in the standard way; the
+    table and cell will be updated accordingly.
+
+    Note, that if you have a table item that is not currently in a table
+    then anything you do to that item other than insert it into a table
+    will result in undefined behaviour.
+
+    Reimplement createEditor() and setContentFromEditor() if you want
+    to use your own widget instead of a QLineEdit for editing cell
+    contents. Reimplement paint() if you want to display custom
+    content.
+
+    It is important to ensure that your custom widget can accept the
+    keyboard focus, so that the user can use the tab key to navigate the
+    table as normal. Therefore, if the widget returned by createEditor()
+    does not itself accept the keyboard focus, it is necessary to
+    nominate a child widget to do so on its behalf. For example, a
+    QHBox with two child QLineEdit widgets may use one of them to
+    accept the keyboard focus:
+
+    \snippet doc/src/snippets/code/src_qt3support_itemviews_q3table.cpp 1
+
+    By default, table items may be replaced by new Q3TableItems
+    during the lifetime of a Q3Table. Therefore, if you create your
+    own subclass of Q3TableItem, and you want to ensure that
+    this does not happen, you must call setReplaceable(false)
+    in the constructor of your subclass.

+    \enum Q3TableItem::EditType
+
+    \target wheneditable
+    This enum is used to define whether a cell is editable or
+    read-only (in conjunction with other settings), and how the cell
+    should be displayed.
+
+    \value Always
+    The cell always \e looks editable.
+
+    Using this EditType ensures that the editor created with
+    createEditor() (by default a QLineEdit) is always visible. This
+    has implications for the alignment of the content: the default
+    editor aligns everything (even numbers) to the left whilst
+    numerical values in the cell are by default aligned to the right.
+
+    If a cell with the edit type \c Always looks misaligned you could
+    reimplement createEditor() for these items.
+
+    \value WhenCurrent
+    The cell \e looks editable only when it has keyboard focus (see
+    Q3Table::setCurrentCell()).
+
+    \value OnTyping
+    The cell \e looks editable only when the user types in it or
+    double-clicks it. It resembles the \c WhenCurrent functionality
+    but is, perhaps, nicer.
+
+    The \c OnTyping edit type is the default when Q3TableItem objects
+    are created by the convenience functions Q3Table::setText() and
+    Q3Table::setPixmap().
+
+    \value Never  The cell is not editable.
+
+    The cell is actually editable only if Q3Table::isRowReadOnly() is
+    false for its row, Q3Table::isColumnReadOnly() is false for its
+    column, and Q3Table::isReadOnly() is false.
+
+    Q3ComboTableItems have an isEditable() property. This property is
+    used to indicate whether the user may enter their own text or are
+    restricted to choosing one of the choices in the list.
+    Q3ComboTableItems may be interacted with only if they are editable
+    in accordance with their EditType as described above.

+    \brief The Q3ComboTableItem class provides a means of using

+
+    \compat
+
+    A Q3ComboTableItem is a table item which looks and behaves like a
+    combobox. The advantage of using Q3ComboTableItems rather than real
+    comboboxes is that a Q3ComboTableItem uses far less resources than
+    real comboboxes in \l{Q3Table}s. When the cell has the focus it
+    displays a real combobox which the user can interact with. When
+    the cell does not have the focus the cell \e looks like a
+    combobox. Only text items (i.e. no pixmaps) may be used in
+    Q3ComboTableItems.
+
+    Q3ComboTableItem items have the edit type \c WhenCurrent (see
+    \l{EditType}). The Q3ComboTableItem's list of items is provided by
+    a QStringList passed to the constructor.
+
+    The list of items may be changed using setStringList(). The
+    current item can be set with setCurrentItem() and retrieved with
+    currentItem(). The text of the current item can be obtained with
+    currentText(), and the text of a particular item can be retrieved
+    with text().
+
+    If isEditable() is true the Q3ComboTableItem will permit the user
+    to either choose an existing list item, or create a new list item
+    by entering their own text; otherwise the user may only choose one
+    of the existing list items.
+
+    To populate a table cell with a Q3ComboTableItem use
+    Q3Table::setItem().
+
+    Q3ComboTableItems may be deleted with Q3Table::clearCell().
+
+    Q3ComboTableItems can be distinguished from \l{Q3TableItem}s and
+    \l{Q3CheckTableItem}s using their Run Time Type Identification
+    number (see rtti()).

+    1, although row and column numbers within Q3Table begin at 0.)

+    the \e viewport.

+
+    \target headers
+    \section1 Headers
+
+    Q3Table supports a header column, e.g. to display row numbers, and
+    a header row, e.g to display column titles. To set row or column
+    labels use Q3Header::setLabel() on the pointers returned by
+    verticalHeader() and horizontalHeader() respectively. The vertical
+    header is displayed within the table's left margin whose width is
+    set with setLeftMargin(). The horizontal header is displayed
+    within the table's top margin whose height is set with
+    setTopMargin(). The table's grid can be switched off with
+    setShowGrid(). If you want to hide a horizontal header call
+    hide(), and call setTopMargin(0) so that the area the header
+    would have occupied is reduced to zero size.
+
+    Header labels are indexed via their section numbers. Note that the
+    default behavior of Q3Header regarding section numbers is overridden
+    for Q3Table. See the explanation below in the Rows and Columns
+    section in the discussion of moving columns and rows.
+
+    \target columnsrows
+    \section1 Rows and Columns
+
+    Row and column sizes are set with setRowHeight() and
+    setColumnWidth(). If you want a row high enough to show the
+    tallest item in its entirety, use adjustRow(). Similarly, to make
+    a column wide enough to show the widest item use adjustColumn().
+    If you want the row height and column width to adjust
+    automatically as the height and width of the table changes use
+    setRowStretchable() and setColumnStretchable().
+
+    Rows and columns can be hidden and shown with hideRow(),
+    hideColumn(), showRow() and showColumn(). New rows and columns are
+    inserted using insertRows() and insertColumns(). Additional rows
+    and columns are added at the  bottom (rows) or right (columns) if
+    you set setNumRows() or setNumCols() to be larger than numRows()
+    or numCols(). Existing rows and columns are removed with
+    removeRow() and removeColumn(). Multiple rows and columns can be
+    removed with removeRows() and removeColumns().
+
+    Rows and columns can be set to be movable using
+    rowMovingEnabled() and columnMovingEnabled(). The user can drag
+    them to reorder them holding down the Ctrl key and dragging the
+    mouse. For performance reasons, the default behavior of Q3Header
+    section numbers is overridden by Q3Table. Currently in Q3Table, when
+    a row or column is dragged and reordered, the section number is
+    also changed to its new position. Therefore, there is no
+    difference between the section and the index fields in Q3Header.
+    The Q3Table Q3Header classes do not provide a mechanism for indexing
+    independently of the user interface ordering.
+
+    The table can be sorted using sortColumn(). Users can sort a
+    column by clicking its header if setSorting() is set to true. Rows
+    can be swapped with swapRows(), columns with swapColumns() and
+    cells with swapCells().
+
+    For editable tables (see setReadOnly()) you can set the read-only
+    property of individual rows and columns with setRowReadOnly() and
+    setColumnReadOnly(). (Whether a cell is editable or read-only
+    depends on these settings and the cell's Q3TableItem.
+
+    The row and column which have the focus are returned by
+    currentRow() and currentColumn() respectively.
+
+    Although many Q3Table functions operate in terms of rows and
+    columns the indexOf() function returns a single integer
+    identifying a particular cell.
+
+    \target cells
+    \section1 Cells
+
+    All of a Q3Table's cells are empty when the table is constructed.
+
+    There are two approaches to populating the table's cells. The
+    first and simplest approach is to use Q3TableItems or Q3TableItem
+    subclasses. The second approach doesn't use Q3TableItems at all
+    which is useful for very large sparse tables but requires you to
+    reimplement a number of functions. We'll look at each approach in
+    turn.
+
+    To put a string in a cell use setText(). This function will create
+    a new Q3TableItem for the cell if one doesn't already exist, and
+    displays the text in it. By default the table item's widget will
+    be a QLineEdit. A pixmap may be put in a cell with setPixmap(),
+    which also creates a table item if required. A cell may contain \e
+    both a pixmap and text; the pixmap is displayed to the left of the
+    text. Another approach is to construct a Q3TableItem or Q3TableItem
+    subclass, set its properties, then insert it into a cell with
+    setItem().
+
+    If you want cells which contain comboboxes use the Q3ComboTableItem
+    class. Similarly if you require cells containing checkboxes use
+    the Q3CheckTableItem class. These table items look and behave just
+    like the combobox or checkbox widgets but consume far less memory.
+
+    Q3Table takes ownership of its Q3TableItems and will delete them
+    when the table itself is destroyed. You can take ownership of a
+    table item using takeItem() which you use to move a cell's
+    contents from one cell to another, either within the same table,
+    or from one table to another. (See also, swapCells()).
+
+    In-place editing of the text in Q3TableItems, and the values in
+    Q3ComboTableItems and Q3CheckTableItems works automatically. Cells
+    may be editable or read-only, see Q3TableItem::EditType. If you
+    want fine control over editing see beginEdit() and endEdit().
+
+    The contents of a cell can be retrieved as a Q3TableItem using
+    item(), or as a string with text() or as a pixmap (if there is
+    one) with pixmap(). A cell's bounding rectangle is given by
+    cellGeometry(). Use updateCell() to repaint a cell, for example to
+    clear away a cell's visual representation after it has been
+    deleted with clearCell(). The table can be forced to scroll to
+    show a particular cell with ensureCellVisible(). The isSelected()
+    function indicates if a cell is selected.
+
+    It is possible to use your own widget as a cell's widget using
+    setCellWidget(), but subclassing Q3TableItem might be a simpler
+    approach. The cell's widget (if there is one) can be removed with
+    clearCellWidget().
+
+    \keyword notes on large tables
+    \target bigtables
+    \section2 Large tables
+
+    For large, sparse, tables using Q3TableItems or other widgets is
+    inefficient. The solution is to \e draw the cell as it should
+    appear and to create and destroy cell editors on demand.
+
+    This approach requires that you reimplement various functions.
+    Reimplement paintCell() to display your data, and createEditor()
+    and setCellContentFromEditor() to support in-place editing. It
+    is very important to reimplement resizeData() to have no
+    functionality, to prevent Q3Table from attempting to create a huge
+    array. You will also need to reimplement item(), setItem(),
+    takeItem(), clearCell(), and insertWidget(), cellWidget() and
+    clearCellWidget(). In almost every circumstance (for sorting,
+    removing and inserting columns and rows, etc.), you also need
+    to reimplement swapRows(), swapCells() and swapColumns(), including
+    header handling.
+
+    If you represent active cells with a dictionary of Q3TableItems and
+    QWidgets, i.e. only store references to cells that are actually
+    used, many of the functions can be implemented with a single line
+    of code.
+
+    For more information on cells see the Q3TableItem documenation.
+
+    \target selections
+    \section1 Selections
+
+    Q3Table's support single selection, multi-selection (multiple
+    cells) or no selection. The selection mode is set with
+    setSelectionMode(). Use isSelected() to determine if a particular
+    cell is selected, and isRowSelected() and isColumnSelected() to
+    see if a row or column is selected.
+
+    Q3Table's support many simultaneous selections. You can
+    programmatically select cells with addSelection(). The number of
+    selections is given by numSelections(). The current selection is
+    returned by currentSelection(). You can remove a selection with
+    removeSelection() and remove all selections with
+    clearSelection(). Selections are Q3TableSelection objects.
+
+    To easily add a new selection use selectCells(), selectRow() or
+    selectColumn().
+
+    Alternatively, use addSelection() to add new selections using
+    Q3TableSelection objects. The advantage of using Q3TableSelection
+    objects is that you can call Q3TableSelection::expandTo() to resize
+    the selection and can query and compare them.
+
+    The number of selections is given by numSelections(). The current
+    selection is returned by currentSelection(). You can remove a
+    selection with removeSelection() and remove all selections with
+    clearSelection().
+
+    \target signals
+    \section1 Signals
+
+    When the user clicks a cell the currentChanged() signal is
+    emitted. You can also connect to the lower level clicked(),
+    doubleClicked() and pressed() signals. If the user changes the
+    selection the selectionChanged() signal is emitted; similarly if
+    the user changes a cell's value the valueChanged() signal is
+    emitted. If the user right-clicks (or presses the appropriate
+    platform-specific key sequence) the contextMenuRequested() signal
+    is emitted. If the user drops a drag and drop object the dropped()
+    signal is emitted with the drop event.

+    Paints the cell at \a row, \a col on the painter \a p. The painter
+    has already been translated to the cell's origin. \a cr describes
+    the cell coordinates in the content coordinate system.
+
+    If \a selected is true the cell is highlighted.
+
+    \a cg is the colorgroup which should be used to draw the cell
+    content.
+
+    If you want to draw custom cell content, for example right-aligned
+    text, you must either reimplement paintCell(), or subclass
+    Q3TableItem and reimplement Q3TableItem::paint() to do the custom
+    drawing.
+
+    If you're using a Q3TableItem subclass, for example, to store a
+    data structure, then reimplementing Q3TableItem::paint() may be the
+    best approach. For data you want to draw immediately, e.g. data
+    retrieved from a database, it is probably best to reimplement
+    paintCell(). Note that if you reimplement paintCell(), i.e. don't
+    use \l{Q3TableItem}s, you must reimplement other functions: see the
+    notes on large tables.
+
+    Note that the painter is not clipped by default in order to get
+    maximum efficiency. If you want clipping, use code like this:

+    Q3TableItem::isReplaceable() is false then the cell is asked to
+    create an appropriate editor (using Q3TableItem::createEditor()).

+
