A Model dialog causes a qgraphicsscene to paint in the background

[keksi venksi]

When I open a model dialog above the qgraphicsscene , If the focus is on the dialog the qgraphicsscene is painting unwantedly . Also when I resize the dialog , it also causes the qgraphicsscene to paint unwantedly (means whenever I do any operations in the dialog , the scene is painting something at the background ... like rendering the scene ).
Can anyone tell on how to find out the cause for the scene painting and to avoid it .... ?
Replies are highly appreciated :)

Hi
People will :) But can be in different time zones from you
so please allow 24 hours before bumping the post.

In the meantime you can enhance your post with
platform + Qt version.

Also please show the code to display the dialog.

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.

@SGaist

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 ?
