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.
