QListWidget painting issue

**guilugi** · 13th April 2007, 15:08

Okay, here is an example I just wrote, I can reproduce my bug with it.

It is an imageviewer based on a qtreeview to browse local disks, and a listwidget to display thumbnails.

I'm using a QThread subclass dedicated to process the thumbnails smoothly (in fact, I use magick code, but here, I made an ugly Qt version

) : it emits a signal once an image is ready, and the corresponding item is being updated.

Here, I can easily reproduce the bug on any directory that contain images...
Randomly, the app crashes, because I don't handle really well the thread (I made it really quickly) : it crashes sometimes when you change directory while the thread is processing..)

Hope some of you can confirm the visual issue ONLY

Guilugi.

Sorry, no luck. The attached screenshot was taken with Qt 4.2.3 on X11.

Ok, thanks...It must really be my distrib...I'm checkin on Win32 right now.

EDIT : I just compiled this example with Qt 4.2.3 on my WinXP computer, it's also quite messy.

I'm posting to Trolltech ;-)

Thanks for your help Jpn

Okay, this issue will probably be rejected by Trolltech..

I just purged all my Debian Qt4 packages, and compiled my own 4.3.0 version, and it's much much better, this particular issue has disappeared
