NEWS (dd.MM.yyyy)

• 29.09.2009 as of lazarus r 21913 qt-4.5.XX is default , minimum bindings version is 1.72. No more USE_QT_XX defines
  
• 18.09.2008 Trolltech released qt-4.4.2. Changes: http://trolltech.com/developer/notes/changes/changes-4.4.2/
  

Fixed many bugs & regressions.

• 31.08.2008 I'm testing 4.4.X for about two weeks (4.4.2 snapshots currently - 4.4.1 have some nasty bugs).

It looks much better than 4.3.XX - no flickering, faster, fixed some ugly QPainter bugs, fixed event queue bug 
(now I reverted QEventFocusIn & QEventFocusOut into my local svn copy (svn r. 14361)). 
Lazarus IDE feels much better with 4.4.X than with 4.3.X.
There's no special changes for 4.4, only r.14361 is out of game.

• 22.02.2008 Trolltech released qt-4.3.4. Changes: http://trolltech.com/developer/notes/changes/changes-4.3.4/
  

Fixes for QCoreApplication events, QComboBox crash fixed ...

• 05.12.2007 Trolltech released qt-4.3.3. Changes: http://trolltech.com/developer/notes/changes/changes-4.3.3/
  

QPainter supports justified text in overloaded QPainter::drawText() 
Fixes for QMainWindow, QMdiArea, QMdiSubWindow.
Fixes QPixmap bug with scaling & shifting by half a pixel.
Fixes for QFileDialog, QListView, QTreeView etc ....
Looks like a nice update.

• 03.10.2007 Trolltech released qt-4.3.2. Changes: http://trolltech.com/developer/notes/changes/changes-4.3.2/
• 01.10.2007 I've compiled & used Lazarus Qt IDE on intel Mac. Screenshoot is here http://wiki.lazarus.freepascal.org/Image:macosxqt.png
  
• 07.08.2007 Trolltech released qt-4.3.1. Changes are here http://trolltech.com/developer/notes/changes/changes-4.3.1/

My TODO list

1. Fix MDI part of Qt since DnD doesn't work inside mdichilds (it cannot since MDIChild have to be a child MDIForm (LCL part)).(0.9.27)
2. Prepare changes for qt 4.4.X series (0.9.27), probably when 4.4.3 released, or even wait for 4.5.X, cause RasterOps are inside 4.5.

KNOWN BUGS IN QT-4.5.3 - (visible in LCLQt)

1. Plastique,Cleanlooks style - combobox, checkbox doesn't show focus rect when focused by pressing ENTER and SelectNext(ActiveControl, True, True) from another control (TAB KEY WORKS OK) - have patch for Qt.
2. WindowsXP style - checkbox doesn't show focus rect for same reason as Plastique checkbox. - have patch for Qt.
3. QStatusBar - size grip & last item isn't visible (if we have few items) if our main window started as wsMaximized. Issue submitted to Qt http://bugreports.qt.nokia.com/browse/QTBUG-4334
