Hi,

A modal dialog doesn't block the painting from happening. If you move a modal dialog over any application, it is expected than what was under the dialog before you move the dialog appear properly after you moved it.

Hi,

Thanks for your reply . You are correct . It will paint but my problem is when ever we open a model dialog above the qgraphicsscene . At first everything looks fine . But when we resize the dialog unwantedly the scene flickers(Ab normal behavior ) .Also when ever the focus comes to dialog the scene's view portion width flickers .

How are you opening that dialog ?

Hi ,,,
"How are you opening that dialog ? "
there is a button above the qgraphicsscene if i click on it a normal slot will open the dialog (custom dialog) ... this is what the normal scenario ...

Is it ok or by which way you are asking ?

[SGaist]

I meant are you calling exec on your dialog or open ?

@SGaist

I'm calling it with show() functionality ...
I would like make a note such that our custom dialog is not like dialog kind of thing its a widget which will be shown as a dialog

[SGaist]

Ok, I just realized that I have misread something. What is your "model dialog" doing ?

I've understood that it was a modal dialog.

Yup its a modal dialog ... I have a lot of modal dialog in my app when ever some modal dialog has been opened or after opening the modal dialog if I do some operation in the dialog(Like FocusEvent is activated ) the QGraphicsScene flickers or it looks like scene rendering happens with some irregular value ...
Note : If I do something in the modal dialog it reflects some irregular behaviour with the QGraphicsScene

[SGaist]

Can you explain then how you are creating your modal dialog ?
