Description Lukasz Wojtylak 2004-02-09 00:17:42 UTC

Version:           3.0.0 (using KDE KDE 3.2.0)
Installed from:    Compiled From Sources
Compiler:          gcc-3.3.1 
OS:          Linux

When "combobox effect" is set to "animate" in the control center, toolbar
combo views don't popup their drop-down lists (thus appearing to be  empty). If I comment out UI effect test (file lib/widgets/qcomboview.cpp, lines 780--791), leaving lb->show() only, everything's ok. I have Qt (3.2.1) compiled with effects enabled (without QT_NO_EFFECTS flag) and all other drop-down lists in all combo boxes in Qt and KDE applications work as expected.

KDevelop ??????

Comment 2 Lukasz Wojtylak 2004-02-09 20:44:18 UTC

Yes, KDevelop. It applies to a special widget class KDevelop maintains for itself, declared in kdevelop-3.0.0/lib/widgets/qcomboview.h, defined in kdevelop-3.0.0/lib/widgets/qcomboview.cpp. All stock Qt and KDE widgets work OK for me.

Comment 3 Alexander Dymo 2004-02-09 23:43:22 UTC

Confirmed. Sacu, maybe this is the problem you had with comboview?

Comment 4 Alexander Dymo 2004-02-09 23:57:31 UTC

CVS commit by dymo: 

Disabled combo box animation because this doesn't work anymore.

Hi Alexander, that's exactly my problem. And it seems solved for me too, now :-)

Thanks Lukasz! You don't imagine how many hours i already spend on looking qcomboview.cpp up and down searching for this problem :-)

Cheers Sascha

Comment 6 Lukasz Wojtylak 2004-02-10 11:33:32 UTC

I can imagine, since my first hypothesis was the combos aren't filled up at all and I spent the whole Sunday afternoon to discover the real source of the problem.
