|
|
|
|
- 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

|
|
- 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.
|
|
|

|
|
Fixed SR_CheckBoxFocusRect for empty checkboxes (now inside
|
|
the indicator)

|
|
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.
|
|
|
|

|
|
Fixed memory consumption when QDomElement::setAttribute() is
|
|
called multiple times to change the value of an
|
|
attribute. Fixed a memory leak in QDomDocument::importNode().
|
|
|
|

|
|
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.
|
|
|
|

|
|
Windows only: Fixed boundingRect(QChar) for non true type
|
|
fonts. Fixed some positioning issues with Thai diacritics.

|
|
|
|

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
|
|
|

|
|
-QPainter
|
|
Fixed pos() in combination with transformations save/restore
|
|
pairs. Fixed a bug in the BiDi algorithm.

|
fix (due to floating point arithmetrics). Fixed a matrix
|
|
related crash on Tru64.
|

|
|
function in convertFromImage.
|

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.

|
|
hdc passed to the Windows Common Dialog.
|
|
|
|
- QProcess
|

|
|
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

|
Emit sliderMoved() after the slider was moved.

|
|
not interpreted text

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

to only set left/right/top/bottom as documented, not the
|
|
firstline margin.
|
|
|
|

Move focus to the current tab if the tab with focus is being
|
|
removed.
|
|
|
|

Fixed contentsContextMenuEvent(). Fixed
|
|
adjustRow()/adjustColumn() for multi line sections. Support
|
|
for QApplicaton::globalStrut(). Speed improvements for
|
|
setNumRows(). Improved sizeHint() to include the left/top
|

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.

|
|
|
|
- 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.
|
