****************************************************************************

- QAction

	Avoid emitting activated() twice for actions in a

	toolbar. Possibility to remove an iconset from an action by

	specifying a null iconset.

- QApplication

	Fixed a font sharing problem with setFont(). Fixed window

	close with modality. Don't overwrite an explicitely set font

	with the default font when using the static methods before

	calling the constructor. When the programmer/user explicitly

	sets the style (either with QApplication::setStyle or -style

	command line option), do not reset the style on settings

	changes.

	Windows only: Serialize calls to OutputDebugString, as this

	API is not reentrant. Emit aboutToQuit() when the user logs

	off. Send a focusOut event to the focus widget when the user

	tries to switch applications via Alt+Tab.

	Windows95/98/Me: Fixed enter/leave handling. Among others this

	makes tooltips work more reliable.

	X11 only: Spit out warning then the user passes an invalid

	Display* argument. Fixed figuring out the depth of the visual

	in case a private colormap is supplied. Some startup

	performance improvements with QSettings. Mark the internal

	wakeUpGuiThread() pipe with FD_CLOEXEC. Call XFilterEvent

	before the public X11 event filters to avoid applications

	filtering out events that are necessary for input methods to

	operate.

- QBuffer

	Make IO_Truncate not detach the explicitely shared byte array.

- QButton

	In setPixmap(), avoid relayouting if the new pixmap doesn't

	change the size.

- QCanvasEllipse

	Windows only: Workaround a Windows limitation that doesn't

	support 2x2 ellipse rendering without a pen. Don't try to

	double buffer invalid areas.

- QClipboard

	Flush the clipboard contents when the application object is

	destroyed.

	X11 only: another race condition fixed. Handle paste

	operations with empty data.

- QComboBox

	Accept enter/return key press events on the line edit. Fixed

	vertical alignment of text when a global strut is set. Clip

	drawing of large items. Fixed problem with items not being

	highlighted the first time the popup is shown.

- QCommonStyle

	Fixed SR_CheckBoxFocusRect for empty checkboxes (now inside

	the indicator)

- QComplexText

	Added correct positioning specs for all of thai and lao. Some

	reordering fixes.

- QCustomEvent

	Removed bogus warning on illegal type ids.

- QDataTable

	Don't display a single empty row if result set is empty and

	QuerySize cannot be determined. Don't resize the table after a

	refresh() if the size is already known.

	In closeEvent(), accept the event only when isHidden()

- QDateTime

	Fixed addYears() for days missing in certain years.

- QDns

	Slightly more reliable now, fixed a memory leak.

- QDockArea

	Fixed resizing of a QDockWindow is no longer affected by

	another closed QDockWindow in the same QDockArea.

- QDom

	Fixed memory consumption when QDomElement::setAttribute() is

	called multiple times to change the value of an

	attribute. Fixed a memory leak in QDomDocument::importNode().

- QDragManager

	X11 only: Fixed a dangling pointer case when the current

	widget was deleted. Raise cursor decoration.

	Windows only: Made dropping of URLs work on Japanese Windows98

- QEffects

	More robust through deferred deletion. Some code improvements. 

	X11 only: disable effects on displays with <16bpp (rather then

	falling back to the scrolling).

- QFileDialog

	Fixed problems with '#' in path. Fixed creation on

	non-existing directories. Make previewMode() check if

	the preview widgets are visible. Enable renaming in

	ExistingFiles mode. Fix drag'n'drop for the first click into

	the listbox. Don't auto-complete when saving a file. Enabled

	drag'n'drop of files for all modes.

- QFont

	Windows only: Fixed boundingRect(QChar) for non true type

	fonts. Fixed some positioning issues with Thai diacritics.

	Win95 only: Make symbol fonts work.

	X11 only: Fixed some issues with diacritics in non unicode

	encoded fonts.

- QFontDialog

	Fixed getFont() in case no default font is specified.

- QFrame

	Fixed erasing the margin region for flicker-optimized

	subclasses (e.g. QLineEdit). Turn on focus and mouse-over

	style flags for frame painting.

- QHeader

	Some speed improvements for the sake of QTable and

	QListView. Fix redrawing problems when moving header sections.

- QIconView

	Fixed contentsContextMenuEvent(). Only call

	QIconViewItem::dragLeft() when the cursor has left the

	bounding rect and only call QIconViewItem::dragEnter() when

	the cursor has entered the bounding rect. Some performance

	improvements.

- QInputContext

	X11 only: Improved XFontSet cache (also for cases where the X

	server does not know the locale).

- QKeyEvent

	Windows only: Fixed internal ascii to keycode conversion for

	codes > 0x80.

- QLineEdit

	Fixed doubleclick selection to only use spaces as word

	seperators. Don't validate twice in a row if fixup() did

	nothing. Fixed support for background pixmaps. Improved undo

	mechanism. Respect maxLength() in setText().

- QListBox

	Fixed null-pointer crash in extended selection mode.

- QListView

	Improved auto scrolling. Restrict drop events to items that

	have drop enabled and accept the event. Added more

	null-pointer checks to prevent crashes when reimplementing

	insertItem. Try harder to draw the focus rectangle with an

	appropriate contrast.  Do not resize a stretachable column in

	widthChanged(). Fixed selecting when auto scrolling.

- QLocalFs

	The network protocol for local file systems sets sets the

	right permissions for the QUrlInfo objects if you do a

	QUrlOperator::listChildren().

- QMainWindow

	Fixed orientation handler calls.

- QMenuBar

	Fixed resizing when it was emptied. Caused some strange

	problems in QMainWindow widgets. Allow stealing of focus in

	alt-mode. Activate alt-mode only with the plain Alt key, not

	AltGr.

- QMimeSourceFactory

	Windows only: If a path starts with \\ then it's an absolute

	path pointing to a network drive

- QMovie

	For animated GIFs, use a minimum delay of 10ms. This is

	compatible with both IE and Mozilla and avoids huge loads on

	application and X-Server.

-QPainter

	Fixed pos() in combination with transformations save/restore

	pairs. Fixed a bug in the BiDi algorithm.

	X11 only: some problems when drawing rotated text on Solaris

	fix (due to floating point arithmetrics). Fixed a matrix

	related crash on Tru64.

	Windows only: Draw end pixel in lineTo only for 0-width

	pens. Avoid painting with invalid transformations.

- QPaintDeviceMetrics

	Windows only: Fixed numColors() for 32 bit displays.

- QPixmap

	Windodws only: Fixed array bounds read error in win32

	function in convertFromImage.

- QPopupMenu

	Avoid flickering when showing a just created menu

	immediately. If there is a custom QWhatsThis installed for the

	whole menu but no whatsThis set for the item, use the custom

	QWhatsThis to get the help text.

	MacOS only: improved scrollable popups

- QPrintDialog

	Unix only: Continue parsing the nsswitch.conf file using

	additional services when /etc/printers.conf is not found.

	Windows only: Handle lack of default printers more

	gracefully. Fix reentrancy issues when reading printer dialog

	settings.

- QPrinter

	Unix only: Fixes for 64 bit safety.

	Windows only: fixed a possible double-freeing of memory of a

	hdc passed to the Windows Common Dialog.

- QProcess

	Windows only: Less command quoting for clients that use

	GetCommandLine() directly. Make tryTerminate() robust in case

	the process does not run. Make it possible to start batch

	files with spaces in the filename. Make it safe to call

	qApp->processEvents() in a slot connected to

	QProcess::readyReadStdout().

- QPSPrinter

	Fixed codec for korean postscript fonts (ksc5601.1987-0, not

	the listbox. Don't auto-complete when saving a fileeucKR).

- QRichText

	Fixed a case-sensitive compare for alignment. Fixed a free'd

	memory access problem with floating items on destruction.

- QScrollView

	If a contents mouse event is accepted, don't propagate as

	a normal mouse event.

- QSemaphore

	Fixed race condition in operator -=.

	Unix only: a bit more robust.

- QSettings

	Unix only: Fixed requesting subkeylists for single

	subkeys. Don't read in QSettings stuff in non-gui mode if

	desktop-settings-aware is set to false.

- QSlider

	Emit sliderMoved() after the slider was moved.

- QSocket

	If the read retruns 0, safely assume assume that the peer

	closed the connection. Fixed readyRead sometimes not being

	emitted.

- QSpinBox

	Fixed setValue so it will ignore input but yet

	not interpreted text

- QSqlDatabase

	Fixed a crash on manual deletion of the QApplication object.

- QSqlDriver

	Various fixes and improvements for Oracle, Postgres, MySQL

- QSqlForm

	Fixed crash in clearValues() on empty fields.

- QString

	Fixed setNum(n,base) with n == LONG_MIN and n != 10. Make

	toLong() and toULong() 64bit clean (problems on Tru64).

- QStyle

	Make more use of Style_HasFocus. Enforce a usable size for

	subcontrols for small scrollbars. Improve titlebar drawing

	(e.g. no gradient on 95/NT). Allow drawing of list view

	expand controls without branches .

	In Windows style: increase default PM_MaximumDragDistance

	value.

	Windows only: fixed PM_ScrollBarExtent

- QStyleSheet

	More accurate mightBeRichText() heuristic. Fixed setMargin()

	to only set left/right/top/bottom as documented, not the

	firstline margin.

- QSvgDevice

	Fixed curve command mixup. Some bounding rect fixes. Fixed

	output coordinates for drawArc, drawPie and drawChord. Proper

	x-axis-rotation and other angle fixes for arcs, pies and

	chords. Respect text alignments. No background for Bezier

	the listbox. Don't auto-complete when saving a filecurves.

- QTabBar

	Move focus to the current tab if the tab with focus is being

	removed.

- QTable

	Fixed contentsContextMenuEvent(). Fixed

	adjustRow()/adjustColumn() for multi line sections. Support

	for QApplicaton::globalStrut(). Speed improvements for

	setNumRows(). Improved sizeHint() to include the left/top

	header. Fix for mouse release handling. Update geometry of

	cell widgets when changing rowHeight/colWidth. Fixed

	QTableItem::sizeHint() for items with wordwrap. Catch

	hideColumn() on tables with too few columns. Fixed an endless

	recursion when swapping header sections.

- QTableItem

	Fixed multiple calls to setSpan().

- QTextCodec:

	Initialize locale before loading textcodec plugins. Fixed a

	bug in the unicode -> jisx0208 conversion table.

- QTextEdit	

	Reset cursor on undos that leave us with an empty

	textedit. Quote quotes when exporting rich text. Fixed

	possible crash when appending empty paragraphs like

	"<p>". Some drawing problems fixed. Made removeParagraph() and

	friends work in read-only mode. Fixed cursor blinking with

	setEnabled() / setDisabled(). When exporting HTML, quote the

	src attribute of img tags tags that contains spaces. Made 

	setFormat() much faster in case undo/redo is disabled. Fixed

	double deletion crash when clearing a document with floating

	custom items.

- QToolButton

	In sizeHint() don't reserve space for icons if button has

	only a textlabel. Made popups more robust (e.g. if the slot

	connected to the popup menu results in the destruction of the

	toolbutton)

- QVariant

	Fixed canCast() for Bool -> String conversion. Fixed

	operator== for maps.

- QWaitCondition

	Windows only: Fixed multiple waits()

- QWheelEvent

	X11 only: Support for two-wheel mice. This relies on the

	X-Server option "ZAxisMapping" "4 5 6 7"

	On Windows, we have not found a reliable way to distringuish

	the two wheels. Some drivers use larger deltas, something that

	breaks with other drivers.

- QWidget

	Make focusWidget() return the focus widget even if it has no

	focus policy. In setEnabled(FALSE) always clear the focus.

	Made grabWidget() more robust. Fixed isEnabledTo().

	X11 only: set WM_WINDOW_ROLE instead of WINDOW_ROLE.

	Windows only: fixed widget-origin pixmap backgrounds.

- QWidgetStack

	More fixes to reduce flicker.

- QWorkspace

	Traditional activeWindow() fixes. Make maximizing a window while

	the workspace is invisible work. If the already active window

	is clicked on, transfer focus to the child. Restore focus to

	old subcontrol when changing the active MDI window. Make sure

	a MDI window is not resized below a child widget's minimum

	size. Do not allow resizing windows when we have an active

	popup window.

- QXmlSimpleReader

	Fixed a memory leak for incremental parsing.
