Read access violation error

@Christian-Ehrlicher I use it, but Qt doesn't show me the line that was wrong. Let me show you an image:

[ivanicy]

@artwaw The problem is that I am not using this function. I think that Qt use it in background when I load the items

[Christian Ehrlicher]

Go up the stack until you see from where findItems() is called. Looks like an infinite loop.

[ivanicy]

@Christian-Ehrlicher I can't do that because Qt crashes and close.

[Christian Ehrlicher]

@ivanicy I don't understand. Why can't you go up in the stack trace to see where it crashes? Does the debugger crash?

[ivanicy]

@Christian-Ehrlicher When I try to scroll for the entries Qt doesn't respond and then close itself

[Christian Ehrlicher]

@ivanicy said in Read access violation error:

Qt doesn't respond

What do you mean with 'Qt' here? QtCreator? this is not Qt but an IDE...
I'm pretty sure you call findItems() somewhere in your code.

[ivanicy]

@Christian-Ehrlicher Yes, I mean Qt Creator and no, I don't call findItems anywhere. I don't know if QGraphicsScene use it when I call to the addItem function or something like that but I don't call it explicitly.

[Christian Ehrlicher]

You have no other chance to either reduce you code until it no longer crashes or write a minimal example to reproduce the problem. Also check if the stuff you pass to addItem() are valid.

@ivanicy You can also try to disable parts of your code until it stops crashing then you know roughly where it is. And if you use CVS like Git you can check the changes since last stable version.
