Hi and welcome to devnet,
In between you could use an image sharing site for that.
Anyway, some more information about your setup would be good. Like
For images of my bug : https://3dsystems.teamplatform.com/pages/94919?t=da2ssnhu4f0v
I use : Qt5.0.2 and compiler mingw47_32
I work on windows XP
The problem concern only QFrame, QSpinBox, QComboBox but doesn't affect QPushButton, QProgressBar, QToolBar and others of my Widget. Globaly all of my widget that i refresh cyclically.
It seems to be a problem of refresh or something like that but don't know exactly what ! Is there a memory or a stack that manage that can be full? Or a signal/slot that need to be disconned?
Thanks for for help SGaist
You could try to check your application with KDAB's GammaRay
Thanks i will try.
FYI It works perfectly on windows 7. But I need it on XP.
Thanks for your help
IIRC Xp is not anymore supported by Qt.
What is exactly IIRC?
If I Remember Correctly
IIRC = "If I recall correctly"
AFAIK XP is still supported, however the pre-built Qt Creator might not run on it
