zeljko:
Scrollbars are killing app. Scrollbars are shown inside paintEvent of TCustomControl (eg. TTreeView, TSynEdit etc..), and that works ok for all themes except for kde-4.5.2 oxygen -> raises av about recursive paint event.

sfeinst:
zeljko,

Thank you for looking into this as I do not have any knowledge debugging at that level.  Let me know if you want me to do anything (unfortunately can only look into things when at home).

Out of curiosity, is this something that the creators of the Oxygen theme did that was unconventional (I am not familair with how KDE themes are built) or is it just something the Lazarus QT LCL did not consider as a possibility?

zeljko:
1. Found one problem and fixed (TQtCustomControl's doesn't like showing of scrollbars inside paintevent - only under oxygen).

2. SynEdit constantly crashes (imediatelly), but could not find why or where yet (must extend debug info in qtlcl first  so then I'll know more).

3.Don't expect fast fix since I don't have enough spare time to dig into (especially because I'm using PCLinuxOS under vmware so it isn't so fast).

4.In the meantime, use lazarus with original qt styles eg. -style plastique, or run qtconfig-qt4 and set default style for qt4 apps (then you can run lazarus from desktop via startlazarus).

ADDON: It doesn't crash when running via valgrind.I have problem with mentioned distribution since there's no debuginfo packages for qt and others, so cannot debug it properly.


zeljko:
At least got good gdb output (Fedora 13 KDE-4.4 with oxygen + Qt-4.7 build from koji.fedoraproject.org ).Don't know who's guilty in this case but qtlcl is definitely not , but think that qt-4.7 is buggy here, and I hope that 4.7.1 will fix this problem (maybe it's already fixed in qt-4.7.1 git repo).
NOTE that pure scrollbar on form crashes complete app.
