    \namespace Qt

    \brief The Qt namespace contains miscellaneous identifiers
    used throughout the Qt library.

    \ingroup misc
*/

/*!
    \enum Qt::Orientation

    This type is used to signify an object's orientation.

    \value Horizontal
    \value Vertical

    Orientation is used with QScrollBar for example.
*/

/*!
    \enum Qt::AlignmentFlag

    This enum type is used to describe alignment. It contains
    horizontal and vertical flags that can be combined to produce
    the required effect.

    The \l{TextElideMode} enum can also be used in many situations
    to fine-tune the appearance of aligned text.

    The horizontal flags are:

    \value AlignLeft Aligns with the left edge.
    \value AlignRight Aligns with the right edge.
    \value AlignHCenter Centers horizontally in the available space.
    \value AlignJustify Justifies the text in the available space.
    \omitvalue AlignAuto

    The vertical flags are:

    \value AlignTop Aligns with the top.
    \value AlignBottom Aligns with the bottom.
    \value AlignVCenter Centers vertically in the available space.

    You can use only one of the horizontal flags at a time. There is
    one two-dimensional flag:

    \value AlignCenter Centers in both dimensions.

    You can use at most one horizontal and one vertical flag at a
    time. Qt::AlignCenter counts as both horizontal and vertical.

    Three enum values are useful in applications that can be run in
    right-to-left mode:

    \value AlignAbsolute  If the widget's layout direction is
        Qt::RightToLeft (instead of Qt::LeftToRight, the default),
        Qt::AlignLeft refers to the \e right edge and Qt::AlignRight
        to the \e left edge. This is normally the desired behavior.
        If you want Qt::AlignLeft to always mean "left" and
        Qt::AlignRight to always mean "right", combine the flag with
        Qt::AlignAbsolute.
    \value AlignLeading  Synonym for Qt::AlignLeft.
    \value AlignTrailing  Synonym for Qt::AlignRight.

    Masks:

    \value AlignHorizontal_Mask
    \value AlignVertical_Mask

    Conflicting combinations of flags have undefined meanings.
*/

/*!
    \enum Qt::ApplicationAttribute

    This enum describes attributes that change the behavior of
    application-wide features. These are enabled and disabled using
    QCoreApplication::setAttribute(), and can be tested for with
    QCoreApplication::testAttribute().

    \value AA_ImmediateWidgetCreation Ensures that widgets are created
           as soon as they are constructed. By default, resources for
           widgets are allocated on demand to improve efficiency and
           minimize resource usage. Setting or clearing this attribute
           affects widgets constructed after the change. Setting it
           tells Qt to create toplevel windows immediately.
           Therefore, if it is important to minimize resource
           consumption, do not set this attribute.

    \value AA_MSWindowsUseDirect3DByDefault Is a Windows specific
           attribute, that will make the Direct3D paint engine the
           default Qt widget paint engine.  Note that you can toggle
           usage of the Direct3D engine on individual QWidgets by
           setting/clearing the \c WA_MSWindowsUseDirect3D attribute
           on a specific widget. \bold {This functionality is
           experimental}.

    \value AA_DontShowIconsInMenus Actions with the Icon property won't be
           shown in any menus unless specifically set by the
           QAction::iconVisibleInMenu property.

           Menus that are currently open or menus already created in the native
           Mac OS X menubar MAY NOT pick up a change in this attribute. Changes
           in the QAction::iconVisibleInMenu property will always be picked up.

    \value AA_NativeWindows Ensures that widgets have native windows.

    \value AA_DontCreateNativeWidgetSiblings Ensures that siblings of native
           widgets stay non-native unless specifically set by the
           Qt::WA_NativeWindow attribute.

    \value AA_MacPluginApplication Stops the a Qt mac application from doing
           specific initializations that do not necessarily make sense when using Qt
           to author a plugin. This includes avoiding loading our nib for the main
           menu and not taking possession of the native menu bar.

/*!
    \enum Qt::MouseButton

    This enum type describes the different mouse buttons.

    \value NoButton        The button state does not refer to any
    button (see QMouseEvent::button()).
    \value LeftButton      The left button is pressed, or an event refers
    to the left button. (The left button may be the right button on
    left-handed mice.)
    \value RightButton     The right button.
    \value MidButton       The middle button.
    \value XButton1        The first X button.
    \value XButton2        The second X button.

    \omitvalue MouseButtonMask

*/

/*!
    \enum Qt::KeyboardModifier

    This enum describes the modifier keys.

    \value NoModifier       No modifier key is pressed.
    \value ShiftModifier    A Shift key on the keyboard is pressed.
    \value ControlModifier  A Ctrl key on the keyboard is pressed.
    \value AltModifier      An Alt key on the keyboard is pressed.
    \value MetaModifier     A Meta key on the keyboard is pressed.
    \value KeypadModifier   A keypad button is pressed.
    \value GroupSwitchModifier X11 only. A Mode_switch key on the keyboard is pressed.

    \omitvalue KeyboardModifierMask

    \note On Mac OS X, the \c ControlModifier value corresponds to
    the Command keys on the Macintosh keyboard, and the \c MetaModifier value
    corresponds to the Control keys. The \c KeypadModifier value will also be set
    when an arrow key is pressed as the arrow keys are considered part of the
    keypad.

    \note On Windows Keyboards, Qt::MetaModifier and Qt::Key_Meta are mapped
    to the Windows key.

    This enum provides shorter names for the keyboard modifier keys
    supported by Qt.

    \bold{Note:} On Mac OS X, the \c CTRL value corresponds to
    the Command keys on the Macintosh keyboard, and the \c META value
    corresponds to the Control keys.

    \value SHIFT The Shift keys provided on all standard keyboards.
    \value META The Meta keys.
    \value CTRL The Ctrl keys.
    \value ALT The normal Alt keys, but not keys like AltGr.
    \value UNICODE_ACCEL The shortcut is specified as a Unicode code

    \enum Qt::ConnectionType

    This enum describes the types of connection that can be used between signals and
    slots. In particular, it determines whether a particular signal is delivered to a
    slot immediately or queued for delivery at a later time.

    \omitvalue AutoCompatConnection
    \value DirectConnection  When emitted, the signal is immediately delivered to the slot.
    \value QueuedConnection  When emitted, the signal is queued until the event loop is
                             able to deliver it to the slot.
    \value
    BlockingQueuedConnection Same as QueuedConnection, except that the current thread blocks
                             until the slot has been delivered. This connection type should
                             only be used for receivers in a different thread. Note that misuse
                             of this type can lead to dead locks in your application.
    \value AutoConnection    If the signal is emitted from the thread
                             in which the receiving object lives, the
                             slot is invoked directly, as with

                             Qt::QueuedConnection.

    With queued connections, the parameters must be of types that are known to
    Qt's meta-object system, because Qt needs to copy the arguments to store them
    in an event behind the scenes. If you try to use a queued connection and
    get the error message

           QImage::depth() depth\endlink 1 and contains only
           black and white pixels, the pixmap becomes monochrome.
    \value ColorOnly The pixmap is dithered/converted to the
           \link QPixmap::defaultDepth() native display depth\endlink.
    \value MonoOnly The pixmap becomes monochrome. If necessary,
           it is dithered using the chosen dithering algorithm.

    Dithering mode preference for RGB channels:

    \value DiffuseDither (default) - A high-quality dither.
    \value OrderedDither A faster, more ordered dither.
    \value ThresholdDither No dithering; closest color is used.

    Dithering mode preference for alpha channel:

    \value ThresholdAlphaDither (default) - No dithering.
    \value OrderedAlphaDither A faster, more ordered dither.
    \value DiffuseAlphaDither A high-quality dither.
    \omitvalue NoAlpha

    Color matching versus dithering preference:

    \value PreferDither (default when converting to a pixmap) - Always dither
           32-bit images when the image is converted to 8 bits.
    \value AvoidDither (default when converting for the purpose of saving to
           file) - Dither 32-bit images only if the image has more than 256
           colors and it is being converted to 8 bits.

    \enum Qt::WidgetAttribute

    \keyword widget attributes

    This enum type is used to specify various widget attributes.
    Attributes are set and cleared with QWidget::setAttribute(), and
    queried with QWidget::testAttribute(), although some have special
    convenience functions which are mentioned below.

    \value WA_AcceptDrops Allows data from drag and drop operations
    to be dropped onto the widget (see QWidget::setAcceptDrops()).

    \value WA_AlwaysShowToolTips Enables tooltips for inactive windows.

    \value WA_ContentsPropagated This flag is superfluous and
    obsolete; it no longer has any effect. Since Qt 4.1, all widgets
    that do not set WA_PaintOnScreen propagate their contents.

    \value WA_CustomWhatsThis Indicates that the widget wants to
    continue operating normally in "What's This?" mode. This is set by the
    widget's author.

    \value WA_DeleteOnClose Makes Qt delete this widget when the
    widget has accepted the close event (see QWidget::closeEvent()).

    \value WA_Disabled Indicates that the widget is disabled, i.e.
    it does not receive any mouse or keyboard events. There is also a
    getter functions QWidget::isEnabled().  This is set/cleared by the
    Qt kernel.

    \omitvalue WA_DropSiteRegistered
    \omitvalue WA_ForceAcceptDrops

    \value WA_ForceDisabled Indicates that the widget is
    explicitly disabled, i.e. it will remain disabled even when all
    its ancestors are set to the enabled state. This implies
    WA_Disabled. This is set/cleared by QWidget::setEnabled() and
    QWidget::setDisabled().

    \value WA_ForceUpdatesDisabled Indicates that updates are
    explicitly disabled for the widget; i.e. it will remain disabled
    even when all its ancestors are set to the updates-enabled state.
    This implies WA_UpdatesDisabled. This is set/cleared by
    QWidget::setUpdatesEnabled().

    \value WA_GroupLeader
        \e{This attribute has been deprecated.} Use QWidget::windowModality
        instead.

    \value WA_Hover Forces Qt to generate paint events when the mouse
    enters or leaves the widget. This feature is typically used when
    implementing custom styles; see the \l{widgets/styles}{Styles}
    example for details.

    \value WA_InputMethodEnabled Enables input methods for Asian languages.
    Must be set when creating custom text editing widgets.
    On Windows CE this flag can be used in addition to
    QApplication::autoSipEnabled to automatically display the SIP when
    entering a widget.

    \value WA_KeyboardFocusChange Set on a toplevel window when
    the users changes focus with the keyboard (tab, backtab, or shortcut).

    \value WA_KeyCompression Enables key event compression if set,
    and disables it if not set. By default key compression is off, so
    widgets receive one key press event for each key press (or more,
    since autorepeat is usually on). If you turn it on and your
    program doesn't keep up with key input, Qt may try to compress key
    events so that more than one character can be processed in each
    event.
    For example, a word processor widget might receive 2, 3 or more
    characters in each QKeyEvent::text(), if the layout recalculation
    takes too long for the CPU.
    If a widget supports multiple character unicode input, it is
    always safe to turn the compression on.
    Qt performs key event compression only for printable characters.
    Qt::Modifier keys, cursor movement keys, function keys and
    miscellaneous action keys (e.g. Escape, Enter, Backspace,
    PrintScreen) will stop key event compression, even if there are
    more compressible key events available.
    Platforms other than Mac and X11 do not support this compression,
    in which case turning it on will have no effect.
    This is set/cleared by the widget's author.

    \value WA_LayoutOnEntireRect Indicates that the widget
    wants QLayout to operate on the entire QWidget::rect(), not only
    on QWidget::contentsRect(). This is set by the widget's author.

    \value WA_LayoutUsesWidgetRect Ignore the layout item rect from the style
    when laying out this widget with QLayout. This makes a difference in
    QMacStyle and QPlastiqueStyle for some widgets.

    \value WA_MacNoClickThrough When a widget that has this attribute set
    is clicked, and its window is inactive, the click will make the window
    active but won't be seen by the widget. Typical use of this attribute
    is on widgets with "destructive" actions, such as a "Delete" button.
    WA_MacNoClickThrough also applies to all child widgets of the widget
    that has it set.

    \value WA_MacOpaqueSizeGrip Indicates that the native Carbon size grip
    should be opaque instead of transparent (the default). This attribute
    is only applicable to Mac OS X and is set by the widget's author.

    \value WA_MacShowFocusRect Indicates that this widget should get a
    QFocusFrame around it. Some widgets draw their own focus halo
    regardless of this attribute. Not that the QWidget::focusPolicy
    also plays the main role in whether something is given focus or
    not, this only controls whether or not this gets the focus
    frame. This attribute is only applicable to Mac OS X.

    \value WA_MacNormalSize Indicates the widget should have the
    normal size for widgets in Mac OS X. This attribute is only
    applicable to Mac OS X.

    \value WA_MacSmallSize Indicates the widget should have the small
    size for widgets in Mac OS X. This attribute is only applicable to
    Mac OS X.

    \value WA_MacMiniSize Indicates the widget should have the mini
    size for widgets in Mac OS X. This attribute is only applicable to
    Mac OS X.

    \value WA_MacVariableSize Indicates the widget can choose between
    alternative sizes for widgets to avoid clipping.
    This attribute is only applicable to Mac OS X.

    \value WA_MacBrushedMetal Indicates the widget should be drawn in
    the brushed metal style as supported by the windowing system. This
    attribute is only applicable to Mac OS X.

    \omitvalue WA_MacMetalStyle

    \value WA_Mapped Indicates that the widget is mapped on screen.
    This is set/cleared by the Qt kernel.

    \value WA_MouseNoMask Makes the widget receive mouse events for
    the entire widget regardless of the currently set mask,
    overriding QWidget::setMask(). This is not applicable for
    top-level windows.

    \value WA_MouseTracking Indicates that the widget has mouse
    tracking enabled. See QWidget::mouseTracking.

    \value WA_Moved Indicates that the widget has an explicit
    position. This is set/cleared by QWidget::move() and
    by QWidget::setGeometry().

    \value WA_MSWindowsUseDirect3D Makes drawing to a widget
    with this attribute set use the Direct3D paint engine, if the
    Direct3D paint engine is available. \bold {This functionality
    is experimental.}

    \value WA_NoBackground This value is obsolete. Use
    WA_OpaquePaintEvent instead.

    \value WA_NoChildEventsForParent Indicates that the widget does
    not want ChildAdded or ChildRemoved events sent to its
    parent. This is rarely necessary but can help to avoid automatic
    insertion widgets like splitters and layouts. This is set by a
    widget's author.

    \value WA_NoChildEventsFromChildren Indicates that the widget does
    not want to receive ChildAdded or ChildRemoved events sent from its
    children. This is set by a widget's author.

    \value WA_NoMouseReplay Used for pop-up widgets. Indicates that the most
    recent mouse press event should not be replayed when the pop-up widget
    closes. The flag is set by the widget's author and cleared by the Qt kernel
    every time the widget receives a new mouse event.

    \value WA_NoMousePropagation Prohibits mouse events from being propagated
    to the widget's parent. This attribute is disabled by default.

    \value WA_TransparentForMouseEvents When enabled, this attribute disables
    the delivery of mouse events to the widget and its children. Mouse events
    are delivered to other widgets as if the widget and its children were not
    present in the widget hierarchy; mouse clicks and other events effectively
    "pass through" them. This attribute is disabled by default.

    \value WA_NoSystemBackground Indicates that the widget has no background,
    i.e. when the widget receives paint events, the background is not
    automatically repainted. \note Unlike WA_OpaquePaintEvent, newly exposed
    areas are \bold never filled with the background (e.g., after showing a
    window for the first time the user can see "through" it until the
    application processes the paint events). This flag is set or cleared by the
    widget's author.

    \value WA_OpaquePaintEvent Indicates that the widget paints all its pixels
    when it receives a paint event. Thus, it is not required for operations
    like updating, resizing, scrolling and focus changes to erase the widget
    before generating paint events. The use of WA_OpaquePaintEvent provides a
    small optimization by helping to reduce flicker on systems that do not
    support double buffering and avoiding computational cycles necessary to
    erase the background prior to painting. \note Unlike
    WA_NoSystemBackground, WA_OpaquePaintEvent makes an effort to avoid
    transparent window backgrounds. This flag is set or cleared by the widget's
    author.

    \value WA_OutsideWSRange Indicates that the widget is outside
    the valid range of the window system's coordinate system. A widget
    outside the valid range cannot be mapped on screen. This is
    set/cleared by the Qt kernel.

    \value WA_PaintOnScreen Indicates that the widget wants to draw directly
    onto the screen. Widgets with this attribute set do not participate in
    composition management, i.e. they cannot be semi-transparent or shine
    through semi-transparent overlapping widgets. \note This flag is only
    supported on X11 and it disables double buffering. On Qt for Embedded
    Linux, the flag only works when set on a top-level widget and it relies on
    support from the active screen driver. This flag is set or cleared by the
    widget's author. To render outside of Qt's paint system, e.g., if you
    require native painting primitives, you need to reimplement
    QWidget::paintEngine() to return 0 and set this flag.

    \value WA_PaintOutsidePaintEvent Makes it possible to use QPainter to
    paint on the widget outside \l{QWidget::paintEvent()}{paintEvent()}. This
    flag is not supported on Windows, Mac OS X or Embedded Linux. We recommend
    that you use it only when porting Qt 3 code to Qt 4.

    \value WA_PaintUnclipped Makes all painters operating on this widget
    unclipped. Children of this widget or other widgets in front of it do not
    clip the area the painter can paint on. This flag is only supported for
    widgets with the WA_PaintOnScreen flag set. The preferred way to do this in
    a cross platform way is to create a transparent widget that lies in front
    of the other widgets.

    \value WA_PendingMoveEvent Indicates that a move event is pending, e.g.,
    when a hidden widget was moved. This flag is set or cleared by the Qt
    kernel.

    \value WA_PendingResizeEvent Indicates that a resize event is pending,
    e.g., when a hidden widget was resized. This flag is set or cleared by the
    Qt kernel.

    \value WA_QuitOnClose Makes Qt quit the application when the last widget
    with the attribute set has accepted closeEvent(). This behavior can be
    modified with the QApplication::quitOnLastWindowClosed property. By default
    this attribute is set for all widgets of type Qt::Window.

    \value WA_Resized Indicates that the widget has an explicit size. This flag
    is set or cleared by QWidget::resize() and QWidget::setGeometry().

    \value WA_RightToLeft Indicates that the layout direction for the widget
    is right to left.

    \value WA_SetCursor Indicates that the widget has a cursor of its own. This
    flag is set or cleared by QWidget::setCursor() and QWidget::unsetCursor().

    \value WA_SetFont Indicates that the widget has a font of its own. This
    flag is set or cleared by QWidget::setFont().

    \value WA_SetPalette Indicates that the widget has a palette of its own.
    This flag is set or cleared by QWidget::setPalette().

    \value WA_SetStyle Indicates that the widget has a style of its own. This
    flag is set or cleared by QWidget::setStyle().

    \value WA_ShowModal \e{This attribute has been deprecated.} Use
    QWidget::windowModality instead.

    \value WA_StaticContents Indicates that the widget contents are north-west
    aligned and static. On resize, such a widget will receive paint events only
    for parts of itself that are newly visible. This flag is set or cleared by
    the widget's author.

    \value WA_StyleSheet Indicates that the widget is styled using a
    \l{Qt Style Sheets}{style sheet}.

    \value WA_TranslucentBackground Indicates that the widget should have a
    translucent background, i.e., any non-opaque regions of the widgets will be
    translucent because the widget will have an alpha channel. Setting this
    flag causes WA_NoSystemBackground to be set. On Windows the
    widget also needs the Qt::FramelessWindowHint window flag to be set.
    This flag is set or cleared by the widget's author.

    \value WA_UnderMouse Indicates that the widget is under the mouse cursor.
    The value is not updated correctly during drag and drop operations. There
    is also a getter function, QWidget::underMouse(). This flag is set or
    cleared by the Qt kernel.

    \value WA_UpdatesDisabled Indicates that updates are blocked (including the
    system background). This flag is set or cleared by the Qt kernel.
    \warning This flag must \e never be set or cleared by the widget's author.

    \value WA_WindowModified Indicates that the window is marked as modified.
    On some platforms this flag will do nothing, on others (including Mac OS X
    and Windows) the window will take a modified appearance. This flag is set
    or cleared by QWidget::setWindowModified().

    \value WA_WindowPropagation Makes a toplevel window inherit font and
    palette from its parent.

    \value WA_MacAlwaysShowToolWindow On Mac OS X, show the tool window even
    when the application is not active.  By default, all tool windows are
    hidden when the application is inactive.

    \value WA_SetLocale Indicates the locale should be taken into consideration
    in the widget.

    \value WA_StyledBackground Indicates the widget should be drawn using a
    styled background.

    \value WA_ShowWithoutActivating Show the widget without making it active.

    \value WA_NativeWindow Indicates that a native window is created for the
    widget. Enabling this flag will also force a native window for the widget's
    ancestors unless Qt::WA_DontCreateNativeAncestors is set.

    \value WA_DontCreateNativeAncestors Indicates that the widget's ancestors
    are kept non-native even though the widget itself is native.

    \value WA_X11NetWmWindowTypeDesktop Adds _NET_WM_WINDOW_TYPE_DESKTOP to the
    window's _NET_WM_WINDOW_TYPE X11 window property. See
    http://standards.freedesktop.org/wm-spec/ for more details. This attribute
    has no effect on non-X11 platforms.

    \value WA_X11NetWmWindowTypeDock Adds _NET_WM_WINDOW_TYPE_DOCK to the
    window's _NET_WM_WINDOW_TYPE X11 window property. See

    attribute for QMenu when torn-off.

    \value WA_X11NetWmWindowTypeUtility Adds _NET_WM_WINDOW_TYPE_UTILITY to the
    window's _NET_WM_WINDOW_TYPE X11 window property. See
    http://standards.freedesktop.org/wm-spec/ for more details. This attribute
    has no effect on non-X11 platforms. \note Qt automatically sets this
    attribute for the Qt::Tool window type.

    \value WA_X11NetWmWindowTypeSplash Adds _NET_WM_WINDOW_TYPE_SPLASH to the

    attribute has no effect on non-X11 platforms. \note Qt
    automatically sets this attribute for QMenus added to a QMenuBar.

    \value WA_X11NetWmWindowTypePopupMenu Adds _NET_WM_WINDOW_TYPE_POPUP_MENU
    to the window's _NET_WM_WINDOW_TYPE X11 window property. See
    http://standards.freedesktop.org/wm-spec/ for more details. This attribute
    has no effect on non-X11 platforms. \note Qt automatically sets this
    attribute for QMenu.

    \value WA_X11NetWmWindowTypeToolTip Adds _NET_WM_WINDOW_TYPE_TOOLTIP to the

/*!
    \enum Qt::WindowType

    \keyword window flag

    This enum type is used to specify various window-system properties
    for the widget. They are fairly unusual but necessary in a few
    cases. Some of these flags depend on whether the underlying window
    manager supports them.

    The main types are

    \value Widget  This is the default type for QWidget. Widgets of
                   this type are child widgets if they have a parent,
                   and independent windows if they have no parent.
                   See also Qt::Window and Qt::SubWindow.

    \value Window  Indicates that the widget is a window, usually
                   with a window system frame and a title bar,
                   irrespective of whether the widget has a parent or
                   not. Note that it is not possible to unset this
                   flag if the widget does not have a parent.

    \value Dialog  Indicates that the widget is a window that should
                   be decorated as a dialog (i.e., typically no
                   maximize or minimize buttons in the title bar).
                   This is the default type for QDialog. If you want
                   to use it as a modal dialog, it should be launched
                   from another window, or have a parent and used
                   with the QWidget::windowModality property. If you make
                   it modal, the dialog will prevent other top-level
                   windows in the application from getting any input.
                   We refer to a top-level window that has a parent
                   as a \e secondary window.

    \value Sheet   Indicates that the widget is a Macintosh sheet.

    \value Drawer  Indicates that the widget is a Macintosh drawer.

    \value Popup   Indicates that the widget is a pop-up top-level
                   window, i.e. that it is modal, but has a window
                   system frame appropriate for pop-up menus.

    \value Tool    Indicates that the widget is a tool window. A tool
                   window is often a small window with a smaller than
                   usual title bar and decoration, typically used for
                   collections of tool buttons. It there is a parent,
                   the tool window will always be kept on top of it.
                   If there isn't a parent, you may consider using
                   Qt::WindowStaysOnTopHint as well. If the window
                   system supports it, a tool window can be decorated
                   with a somewhat lighter frame. It can also be
                   combined with Qt::FramelessWindowHint.
                   \br
                   \br
                   On Mac OS X, tool windows correspond to the
                   \l{http://developer.apple.com/documentation/Carbon/Conceptual/HandlingWindowsControls/hitb-wind_cont_concept/chapter_2_section_2.html}{Floating}
                   class of windows. This means that the window lives on a
                   level above normal windows; it impossible to put a normal
                   window on top of it. By default, tool windows will disappear
                   when the application is inactive.  This can be controlled by
                   the Qt::WA_MacAlwaysShowToolWindow attribute.

    \value ToolTip Indicates that the widget is a tooltip. This is
                   used internally to implement
                   \l{QWidget::toolTip}{tooltips}.

    \value SplashScreen Indicates that the window is a splash screen.
                        This is the default type for QSplashScreen.

    \value Desktop  Indicates that this widget is the desktop. This
                    is the type for QDesktopWidget.

    \value SubWindow  Indicates that this widget is a sub-window, such
                      as a QMdiSubWindow widget.

    There are also a number of flags which you can use to customize
    the appearance of top-level windows. These have no effect on other
    windows:

    \value MSWindowsFixedSizeDialogHint  Gives the window a thin dialog border on Windows.
           This style is traditionally used for fixed-size dialogs.

    \value MSWindowsOwnDC  Gives the window its own display
           context on Windows.

    \value X11BypassWindowManagerHint  Bypass the window
           manager completely. This results in a borderless window
           that is not managed at all (i.e., no keyboard input unless
           you call QWidget::activateWindow() manually).

    \value FramelessWindowHint  Produces a borderless window.
           The user cannot move or resize a borderless window via the window
           system. On X11, the result of the flag is dependent on the window manager and its
           ability to understand Motif and/or NETWM hints. Most existing
           modern window managers can handle this.

    The \c CustomizeWindowHint flag is used to enable customization of
    the window controls. This flag must be set to allow the \c
    WindowTitleHint, \c WindowSystemMenuHint, \c
    WindowMinimizeButtonHint, \c WindowMaximizeButtonHint and \c
    WindowCloseButtonHint flags to be changed.

    \value CustomizeWindowHint  Turns off the default window title hints.

    \value WindowTitleHint  Gives the window a title bar.

    \value WindowSystemMenuHint Adds a window system menu, and
    possibly a close button (for example on Mac). If you need to hide
    or show a close button, it is more portable to use \c
    WindowCloseButtonHint.

    \value WindowMinimizeButtonHint  Adds a minimize button. On
           some platforms this implies Qt::WindowSystemMenuHint for it to work.

    \value WindowMaximizeButtonHint  Adds a maximize button. On
           some platforms this implies Qt::WindowSystemMenuHint for it to work.

    \value WindowMinMaxButtonsHint  Adds a minimize and a maximize
           button. On some platforms this implies Qt::WindowSystemMenuHint for it to work.

    \value WindowCloseButtonHint  Adds a close button. On
           some platforms this implies Qt::WindowSystemMenuHint for it
           to work.

    \value WindowContextHelpButtonHint  Adds a context help button to dialogs.
           On some platforms this implies Qt::WindowSystemMenuHint for it to work.

    \value MacWindowToolBarButtonHint On Mac OS X adds a tool bar button (i.e.,
           the oblong button that is on the top right of windows that have toolbars.

    \value BypassGraphicsProxyWidget Prevents the window and its children from
           automatically embedding themselves into a QGraphicsProxyWidget if the
           parent widget is already embedded. You can set this flag if you
           want your widget to always be a toplevel widget on the desktop,
           regardless of whether the parent widget is embedded in a scene or
           not.

    \value WindowShadeButtonHint

    \value WindowStaysOnTopHint  Informs the window system that the
           window should stay on top of all other windows. Note that
           on some window managers on X11 you also have to pass
           Qt::X11BypassWindowManagerHint for this flag to work
           correctly.

    \value WindowStaysOnBottomHint Informs the window system that the
           window should stay on bottom of all other windows. Note
           that on X11 this hint will work only in window managers
           that support _NET_WM_STATE_BELOW atom. If a window always
           on the bottom has a parent, the parent will also be left on
           the bottom.  This window hint is currently not implemented
           for Mac OS X.

    \value WindowOkButtonHint Adds an OK button to the window decoration of a dialog.
           Only supported for Windows CE.

    \value WindowCancelButtonHint Adds a Cancel button to the window decoration of a dialog.
           Only supported for Windows CE.

    \value WindowType_Mask  A mask for extracting the window type
                            part of the window flags.

    \enum Qt::ItemFlag

    This enum describes the properties of an item:

    \value NoItemFlags It does not have any properties set.
    \value ItemIsSelectable It can be selected.
    \value ItemIsEditable It can be edited.
    \value ItemIsDragEnabled It can be dragged.
    \value ItemIsDropEnabled It can be used as a drop target.
    \value ItemIsUserCheckable It can be checked or unchecked by the user.
    \value ItemIsEnabled The user can interact with the item.
    \value ItemIsTristate The item is checkable with three separate states.

    Note that checkable items need to be given both a suitable set of flags
    and an initial state, indicating whether the item is checked or not.
    This is handled automatically for model/view components, but needs
    to be explicitly set for instances of QListWidgetItem, QTableWidgetItem,
    and QTreeWidgetItem.

    \enum Qt::MatchFlag

    This enum describes the type of matches that can be used when searching
    for items in a model.

    \value MatchExactly     Performs QVariant-based matching.
    \value MatchFixedString Performs string-based matching.
           String-based comparisons are case-insensitive unless the
           \c MatchCaseSensitive flag is also specified.
    \value MatchContains    The search term is contained in the item.
    \value MatchStartsWith  The search term matches the start of the item.
    \value MatchEndsWith    The search term matches the end of the item.
    \value MatchCaseSensitive  The search is case sensitive.
    \value MatchRegExp      Performs string-based matching using a regular
           expression as the search term.
    \value MatchWildcard    Performs string-based matching using a string with
           wildcards as the search term.
    \value MatchWrap        Perform a search that wraps around, so that when
           the search reaches the last item in the model, it begins again at
           the first item and continues until all items have been examined.
    \value MatchRecursive   Searches the entire hierarchy.

    \value ElideLeft    The ellipsis should appear at the beginning of the text.
    \value ElideRight   The ellipsis should appear at the end of the text.
    \value ElideMiddle  The ellipsis should appear in the middle of the text.
    \value ElideNone    Ellipsis should NOT appear in the text.

    Qt::ElideMiddle is normally the most appropriate choice for URLs (e.g.,
    "\l{http://www.qtsoftware.com/careers/movingto/beijing/}{http://www.qtsof...ovingto/beijing/}"),

    \value LowEventPriority Events with this priority are sent after
    events with HighEventPriority or NormalEventPriority.

    Note that these values are provided purely for convenience, since
    event priorities can be any value between \c INT_MAX and \c
    INT_MIN, inclusive. For example, you can define custom priorities
