My TODO list

1. Implement more winapi functions.
   
   • Actually there are still pending problems with some winapi functions.Scrolling eg. TStringGrid with 500 rows with VK_UP or VK_DOWN, eats 70 % cpu while qt3CLX eats max 4-5%, gtk1 & clx are about 3%, gtk2 around 20%. Such scrolling is a PITA on eg. Celeron 2.4.
2. Get SynEdit useable with Qt.
   
   • it's useable but very slow. Deep inspection of SynEdit winapi calls needed (to find out what causes such slowness).
3. Finally, make IDE useable.
   
4. * Fix designer (eg. Focus rect during design time etc....). paul fixed
5. * Fix visibility of runtime components. paul fixed
6. TPrinterSetupDialog .... currently under construction
   
7. Implement missing routines for various controls.
   
8. lazarus bugs:
   
   • http://www.freepascal.org/mantis/view.php?id=9152
     
   • http://www.freepascal.org/mantis/view.php?id=9200
     
9. TStatusBar bug: It's invisible, until we resize form for the first time.
   • Commited workaround in TQtWSStatusBar.ShowHide(), works but doesn't smell good.
     
10. Mouse freezing bug when click on TTabSheet (called TQtWidgetSet.SetCapture()), form can be killed by Alt+F4.
    • Commited workaround until bugfix maded ! paul fixed.
      
11. GetScrollInfo() , SetScrollInfo() needs to be rewritten.
    
12. Make VirtualTree fully useable with qt lcl.
13. Check for Signals bug with TQtTreeWidget (QTreeWidget), as explained in http://www.freepascal.org/mantis/view.php?id=9746
    
14. MenuBar should be created with parent=0 under Mac during form design time. fixed in r12288
    
15. Clipboard problems. Under linux, when Ctrl+C some selected text inside SynEdit, KDE desktop dissapears, when try to paste it into eg. kwrite - kwrite freezes (no respond). MacOsX - almost same problems , under windows we also have problems, cannot copy - paste in between lazarus <-> eg. notepad. fixed with r14958
    
16. Size problem with scrollarea<->viewport (viewport is bigger that area with $workaround patch, or smaller without it eg.TStringGrid) before manual resizing for the first time
17. CodeTools crash when ide compiled without -gl -gh.
18. 1 pixel extra in lines of grids, treeeviews, virtualtree and in expand signs (+,-) of treeview & virtualtree.
