Still experiencing problems with QListWidget (QTableWidget also) and Qt4.2.x...
I hope this will be corrected with Qt 4.3.
Here's a bug that appear when I refresh my view (simple QListWidget in IconMode), labels layout is quite messy...as the screenshot show :)
Any of you experienced that ?
It occurs on Linux, I'll have to check on Windows too.

Could you provide a minimal compilable example reproducing the problem? ;)
Is there anything "custom" involved or are those plain QListWidgetItems?
Yes, I will post it tomorrow...
In fact, those items correspond to the images contained in a directory...
1) I create & add all the items with a unique default pixmap.
2) In a separate thread, I have an ImageMagick module that process thumbnails (it allows me to support a lot of formats :) ), and I emit a reference of the thumbnail once it's ready.
I also add the thumbnail in a custom cache file.
3) I update the corresponding item with this new thumbnail.
The bug always appears when I "refresh" the view (clear()+ reloading of images, fast via cache), except when I set setUniformSizes(true).
Unfortunately (and logically), this last option provoke new issues when I have thumbnails of various sizes.
Thanks for replying ;)

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 :p ) : 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 :D

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

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 ;)
