+Qt 3.0.1 is a bugfix release. It maintains both forward and backward
+compatibility (source and binary) with Qt 3.0.0
+
+
+****************************************************************************
+* General *
+****************************************************************************
+
+- Style Engine fixes
+ Qt 3.0 introduced a new and more flexibile style engine. This
+ release should fix most of the small visual flaws that the new
+ styles introduced. It also greatly improves appearance in
+ right-to-left mode.
+
+- MS-Windows XP
+ This is the first release to fully support Windows XP,
+ including the new themable GUI styles.
+ The Windows XP style can only be built as a plugin, which requires
+ Qt to be configured as a shared library. To build the plugin
+ you must install a Microsoft Platform SDK for October 2001
+ or later. Your INCLUDE and LIB environment variables must
+ point to the respective directories in the SDK installation.
+
+- Reverse (right-to-left) layouts
+ Many classes have improved support for right-to-left layouts.
+
+- Compile fixes
+ Solaris 7 Intel, g++ version 2.8.1.
+
+- Documentation updates
+ Some new and improved diagrams and minor textual revisions.
+
+- Mac only: Drag'n'drop
+ Mac only: QDropEvents can decode HFS flavors.
+
+- X11 only: Multi-head (multi-screen) improvements
+ Support for different TrueColor depths on each head (screen).
+ Drag'n'drop support across multiple screens. Tooltips always
+ stay on the correct screen. Improved OpenGL support on
+ multiple screens. Qt 3.1 will support different color depths
+ on every screen (e.g. one TrueColor screen, one 8-bit
+ PseudoColor and one 8-bit GreyScale).
+
+
+****************************************************************************
+* Library *
+****************************************************************************
+
+- QAction
+ Fixed a memory leak in conjunction with action accelerators.
+ Turn toggle actions off when toggling is turned off with
+ setToggleAction(FALSE);
+
+- QApplication
+ Shared double buffers are cleaned up on destruction.
+ Creating and using multiple QApplications in the same process
+ is supported.
+ - Solaris only: Default to the Interface System font (which is
+ the default for the CDE)
+ - Win32 only: When WM_QUERYENDSESSION is received, _flushall
+ is called to ensure that all open streams and buffers are
+ flushed to disk (or to OS's buffers).
+ Better support for more input methods (e.g. Chinese).
+ Enter events are not propagated to modally blocked widgets.
+ Key_BackTab events are generated rather than Shift+Key_Tab.
+ Floating toolbars are blocked when the application is modal.
+ Move and Resize are disabled in the system menu for
+ maximized toplevel windows
+ - WinXP only: WM_THEMECHANGED messages are handled; widgets
+ are repolished with the appropriate style.
+ - X11 only: Removed misleading warning message for main
+ widgets on heads (screens) other than the default head.
+ Input context: Solved a memory leak in Xlib, and saved a
+ server round trip when updating the microfocushint.
+ Worked around some broken XmbLookupString implementations
+ that do not report buffer overflows correctly.
+ Key events are never given to a widget after clearFocus()
+ has been called for that widget; this is the same behavior
+ as Windows.
+
+- QAquaStyle (MacOS X only)
+ More optimizations and several minor visual bugs fixed.
+
+- QCanvas
+ Erase any exposed empty space when shrinking the canvas.
+
+- QCanvasPixmapArray
+ Initialize the framecount to 0.
+
+- QCanvasView
+ Optimize background pixmaps: potentially they were drawn
+ twice, first untranslated then translated.
+
+- QClipboard (X11 only)
+ The race conditions that cause KDE to lock-up occasionally
+ should now be fixed.
+
+- QComboBox
+ Fixed behavior with non-selectable items. Fixed a crash when
+ calling setCurrentItem(-1). Fixed autoscrolling when dragging
+ the mouse directly after opening the dropdown.
+
+- QColor
+ Make invalid named colors return a non-valid QColor (as
+ documented).
+
+- QColorDialog (Win32 only)
+ Use WStyle_DialogBorder, since resizing this dialog does not
+ make much sense.
+
+- QCommonStyle
+ Respect QApplication::globalStrut() in scroll bars. Support
+ reverse layout in QTitleBar.
+
+- QCursor
+ Safer cleanup of cursor shapes (avoids possible free'd memory
+ read)
+ - Win32 only: fixed application override cursor with mouse
+ grabbing.
+
+- QDate
+ Fixed some possible overflows.
+ - Win32 only: Improve locale support for short day and month
+ names etc. Initialize milliseconds correctly.
+
+- QDateTimeEdit
+ Display AM/PM if set by locale. Improved sizeHint().
+
+- QDockAarea
+ More reliable sizeHint(). Better support for reverse layouts.
+
+- QDockWindow
+ Emit the placeChange() signal more reliably. Avoid floating
+ docks popping up everywhere before they have been positioned
+ and laid out.
+
+- QDesktopWidget
+ - X11 only: When using normal dualhead (not Xinerama), make
+ sure we report the correct screen number.
+ - Win32 only: refresh on WM_DISPLAYCHANGE.
+
+- QFrame
+ New panel styles LineEditPanel and TabWidgetPanel. This was
+ required by the new for Windows XP support.
+
+- QFileDialog
+ Show unicode filenames to the user rather than encoded ASCII
+ (e.g. previously latin1 characters were shown as "%XX"
+ escapes).
+ Fixed multiple-selection of FTP files.
+ Emit signal fileHighlighted in existingfile mode.
+ - Mac only: Fixed existingFolder(). Fixed window position so
+ that it will never fall outside the screen.
+ - Win32 only: since files, directories and drives are not case
+ sensitive, we don't add an extra entry in the paths box if
+ the path already exists but with different case.
+
+- QFileInfo (Unix only)
+ Make sure that symlinks pointing to invalid/non-existing
+ targets are reported as symlinks.
+
+- QFont
+ Ensure a rounded-off value is returned from pointSize().
+ - x11 only: improved line width calculation. Fixed off by one
+ error in interpreting Xft font extents. Allow the use of
+ both Xft and non Xft fonts in the same application. Make
+ sure fonts are antialiased by default when using
+ xftfreetype.
+
+- QFontDialog
+ Prevent re-laying out when the size of the preview label
+ changes.
+
+- QFtp
+ In parseDir(), do not compare English month names to
+ shortMonthName(), since the latter is localized.
+
+- QGList
+ Make self-assignments work.
+
+- QGLWidget
+ Fixed ARGB to RGBA conversion on BigEndian systems.
+ - Win32 only: fixed colormap for 8-bit RGBA GL mode.
+ - X11 only: multiple heads with different color depths fixes.
+
+- QHebrewCodec
+ Assume the bidi algorithm is a reversible operation for the
+ visual 8859-8 codec. This is not true for very complex strings
+ but should hold in most cases.
+
+- QIconSet
+ Fixed detach() to really detach the internal pixmaps. In case
+ no image formats are installed, show black pixmaps rather than
+ ASSERT.
+
+- QImage
+ Allow 16-bit DIBs. Allow > 32767 level PNMs.
+ Fixed smoothscale() for the following bug: whenever
+ (new_width / original_width * 4096) is not an integer the last
+ column of the scaled image is black.
+
+- QImageIO
+ Fixed plugin loading in cases where the image format is
+ explicitly defined.
+
+- QInputDialog
+ Disable the OK button when input is not Acceptable.
+ (See QValidator.)
+
+- QLabel
+ When showing rich text with tables (via QSimpleRichtext),
+ avoid drawing the table background.
+
+- QLayout
+ In reverse layout mode: fix off by one error when laying out
+ right to left or bottom to top.
+
+- QLineEdit
+ Fixed offset calculation for horizontal scrolling. Invoke
+ validator when the user presses Backspace or
+ Delete. Compression of the undo/redo stack fixed. Security: do
+ not reveal the position of spaces with Ctrl+RightArrow or
+ Ctrl+LeftArrow in password mode.
+
+- QListBox
+ Append items at the proper position even after sorting the
+ content. Made QWidget::setBackgroundMode() work correctly.
+
+- QListBoxPixmap
+ Use the function pixmap() when drawing the pixmap, so users
+ can reimplement QListBoxPixmap::pixmap().
+
+- QListView
+ Fix misalignment of checkbox click zone. Make the selected and
+ focus rectangles cover the entire column for QCheckListItems
+ if the listview root is not decorated. Make
+ QWidget::setBackgroundMode() on the viewport work correctly.
+ Comply with user interface guidelines: clear the selection
+ when a click is in an empty area unless the Ctrl key is down.
+ Fixed possible crash when starting a rename with a double
+ click. Smarter ensureItemVisible(). Draw listview background
+ in paintEmptyArea() with the current style. Ensure the
+ listview always has a current item.
+
+- QMainWindow
+ Better laying out of dockareas when they are all empty.
+ Otherwise an empty QMainWindow looks unappealing in a
+ workspace. Maintain the toplevel layout's resize mode.
+
+- QMessageBox
+ Avoid double deletion if the parent is destroyed while the
+ messagebox is open. Support y/n/c shortcuts without needing
+ the Alt key modifier.
+
+- QMovie
+ Allow pause() and restart() with MNG.
+
+- QMultiLineEdit
+ Remove internal trailing space when returning a textline with
+ textLine(int) and querying lineLength(int).
+
+- QPainter
+ The boundingRect() should now work properly for the
+ combination richtext, right-aligned and an empty initial rect.
+ Handle DontClip-flag in the painter's complex drawText()
+ function. Reset the cached composition matrix (and inverse)
+ when reinitialising a painter.
+
+- QPicture
+ Fixed the loading of binaries from older Qt versions.
+
+- QPixmap
+ grabWidget(): when the widget sets WRepaintNoErase it might
+ erase itself with the non-redirected QWidget::erase(); restore
+ those areas.
+ - X11 only: (with XRENDER extension) when copying a pixmap,
+ bitBlt the entire data into the new pixmap instead of using
+ alpha composition.
+
+- QPopupMenu
+ Fixed strange side effects with the menu effects. Support
+ minimumSize() for popups. Fixed a navigation issue where
+ Key_Right under certain circumstances was not propagated to
+ the menu bar. Speedups when disabling/enabling menu items
+ before showing them.
+ - X11 only: Fixed mouse and keyboard grabbing side effects
+ with popup menu effects enabled.
+
+- QPrintDialog (built-in dialog)
+ Use the text in the lineedit for the file dialog.
+
+- QPrinter
+ Fixed crash when printing with incomplete combined unicode
+ fonts.
+ - Win32 only: fixed a very rare and mysterious crash.
+
+
+- QPSPrinter
+ Make sure the fontPath is read correctly by the postscript
+ driver, and the qtconfig program. Small memory leaks closed.
+ Better support for Asian printing. Limit line length of
+ Postscript DSC comments to 255 chars (as per the postscript
+ specification).
+
+- QRichText
+ Fixed handling of &nbsp. Support both <qt title="..."> and
+ <title>. Avoid painting \n at the end of lines (these
+ sometimes appeared as an empty unicode box). Fixed find() in
+ "whole words only" mode. Fixed unicode auto alignment. Made
+ cursor movement in BiDi paragraphs compliant with MS-Windows.
+ Fixed paragraph right and center alignments when using <br>
+ tags. Fixed superscript/subscript confusion.
+
+- QScrollBar
+ Allow scrolling with modifier keys pressed.
+
+- QScrollView
+ Made autoscrolling work with drag and drop. Never generate
+ paintevents that are outside the visible area.
+
+- QSettings
+ - Unix only: search paths are valid for individual objects,
+ NOT every object (windows behavior). When reading files,
+ don't replace the old groups with contents of the new
+ groups; merge them instead. Properly escape backslashes and
+ newlines.
+ - win32 only: improved error handling. Fixed subKeyList() and
+ entryList() for empty paths.
+
+- QSimpleRichText
+ Correctly transform clipping rectangle.
+
+- QSizeGrip
+ Reverted sizeHint() to the old size to avoid making the
+ statusbar a tiny bit too big. Support right-to-left layout.
+
+
+- QSgiStyle
+ Made the combobox arrow look nicer. Fixed disabled combobox
+ drawing.
+
+- QSlider
+ Fixed click handling for reverse layouts.
+
+- QSpinBox
+ Usability fix: when changing a value with the up/down arrow
+ keys or with the arrow buttons, select the new value.
+
+- QSplitter
+ Use the actual QSplitter pointer as documented (and not a
+ QSplitterHandle pointer) as the parameter to the
+ QStyle::sizeForContents() call. Fixed reverse layouts when
+ splitter movement is constrained.
+
+- QSqlRecord
+ Fixed double increment of the iterator in certain
+ circumstances.
+
+- QString
+ Fixed QString::setLatin1() when the length parameter is 0.
+ - Unix only: Use strcoll() in QString::localeAwareSorting().
+ - Mac only: clarify that local8Bit() is always utf8().
+
+- QStyle
+ New frame styles for tab widgets, window frames and line edit
+ controls. This was required by the new support for Windows XP.
+ Added SH_ScrollBar_StopMouseOverSlider style hint so that one can
+ turn on (or off) the ability to stop pageup/pagedown when the
+ slider hits the mouse (this is needed for Aqua on MacOS X).
+
+- QSvgDevice
+ Many fixes for saving and restoring attributes that are not
+ part of QPainter. Processing of 'tspan' elements. Now uses
+ double instead of int for internal 'path' arithmetic for
+ better scaling results. Supports QPicture's coordinate
+ transformations.
+
+- QTabBar
+ Fixed the focus rectangles and spacing with icons and label
+ texts.
+
+- QTable
+ Improved layout in right-to-left mode. Fixed adjustRow() when
+ using header items with icon sets. Do not let hidden
+ columns/rows re-appear when adjusting. Update header correctly
+ when changing a table's dimensions. Correctly reset the
+ updatesEnabled flag in sortColumn(). Fixed modifying the
+ contents of a combobox or checkbox table item while it is the
+ current cell.
+
+- QTableItem
+ Make sure an item cannot span over a table's maximum number of
+ rows and columns.
+
+- QTabWidget
+ Constrain the sizehint to avoid having oversized dialogs.
+
+- QTextCode
+ Rename iso8859-6-I to to 8859-6. The old name is still
+ supported for backwards compatibility.
+ - Win32: implemented locale().
+ - Mac: implemented locale().
+
+- QTextDrag (Win32 only)
+ Performance improvements in encodedData().
+
+- QTextEdit
+ Fixed HTML output. New property tabStopWidth. Fixed append()
+ and made it smarter: it only scrolls to the end if the view
+ was scrolled to the end before. Proper reformatting when
+ switching word wrap policies. Do not blink the cursor when the
+ textedit is disabled. Make isModified() return the new value
+ in slots connected to the modificationChanged() signal.
+ - X11 only: middle mouse selection pasting sets the cursor
+ position.
+
+- QTextStream
+ Faster string output in latin1 mode.
+
+- QThread
+ - Unix only: initialize threads in non-GUI mode as well.
+ - Win32 only: fixed the initial value of QThread::running().
+
+- QToolButton
+ Fixed unwanted occurences of delayed popup menus.
+
+- QUrlOperator
+ Fixed the cache, so that QUrlInfo::name() is set correctly for
+ renamed files. This bug also affected QFileDialog. More
+ careful check whether a file is writable before renaming or
+ deleting it.
+
+- QValueVector
+ Make operator==() const. Fixed some sharing issues.
+
+- QVariant
+ Fixed a few memory leaks when casting complex values to simple
+ types. Faster operator==().
+
+- QWaitCondition (Win32 only)
+ Fixed wakeAll().
+
+- QWhatsThis
+ Make QWidget::customWhatsThis() work with menu accelerators.
+ Avoid infinite loops with menu effects.
+
+- QWidget
+ Fix default focus so that setTabOrder( X, Y ); setTabOrder( Y,
+ Z ); gives focus to X, not Y or Z. Closing a modal dialog with
+ a double click on a widget could result in a mouse release
+ event being delivered to the widget underneath; this has been
+ fixed.
+ Set/Reset WState_HasMouse on DragEnter/DragLeave.
+ - Win32 only: obey WPaintUnclipped. Make reparent() with 0,0
+ positions do the requested positioning.
+ - X11 only: when reparenting widgets to/from toplevel, make
+ sure the XdndAware property is set. Make input methods work
+ with servers other than kinput2. More fixes for 4Dwm's
+ incompliance with ICCCM 4.1.5 regarding geometry handling.
+ When hiding toplevel windows, we call XFlush() to avoid
+ having popup menus hanging around grabbing the mouse and
+ keyboard while the application is busy. Obey the 'erase'
+ value in repaint(const QRegion& reg, bool erase).
+
+- QWindowsStyle
+ Various visual fixes, including fixes for right-to-left
+ mode. Most significantly the light source now comes from the
+ top left also in reverse layout the same as modern versions of
+ Windows.
+
+- QWorkspace
+ Support document windows without title bars. Scroll to top
+ left corner when cascading/tiling a scrolled workspace. Define
+ a proper baseSize() for workspace children. Fix some side
+ effects with the workspace's maximize controls on Windows
+ style. Don't raise windows over scrollbars. Clients can now
+ call adjustSize() on the workspace when their sizeHint()
+ changes. When showing two scrollbars, maintain a solid corner.
+ Obey a document window's maximum size when tiling.
