Revision as of 22:08, 18 September 2008

This is my page ? ;) Hi I'm Zeljan Rikalo (everybody calls me Zeljko), currently trying to finish qt4 interface for lazarus. Any feedback about qt-lcl from linux,win32 or mac is welcome (patches also). All about Qt interface you can find at


NEWS (dd.MM.yyyy)

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.

Fixes for QCoreApplication events, QComboBox crash fixed ...

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.

My TODO list

  1. Check for Signals bug with TQtTreeWidget (QTreeWidget), as explained in http://www.freepascal.org/mantis/view.php?id=9746
  2. 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)
  3. Fix OnExit() & OnEnter() behaviour of LCL. Depends on proper form's activate & deactivate, and widgetset's ability to control that.(0.9.27) eg. Gtk1 cannot do that so some hackish code is needed to get Delphi behaviour.
  4. 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.
