Hi,

Please provide the code reproducing the problem.

Note that it is impossible. It depends on 3rd party libs and it's also closed source because it belogns to the company where I work.

Don't worry about it, I will debug the application deeply.

Thanks,

I don't want the code of your program. I want you to write (from scratch) a short program (30 lines of code max) that will contain only the code necessary to reproduce the problem. Writing such a test case is very often enough to pinpoint and fix the problem on your own.

Hi,

Thanks Wysota,

It seems to not be the QLabel update to produce the crash. The problem in other pice of code that I'm searching for. Commenting some lines of my code it seems to not crash so now I need to find, into a lot of code, where I'm doing something wrong.

I've tryied to update a QLabel with a signal emmited from a thread in a little test and it works perfectly.

Thanks,

That test proves nothing really (the fact it didn't crash when you tested it doesn't mean it won't crash at all). But I can tell you this is correct - as long as you use signals and slots and thread affinity of objects involved is correct, it will work properly
