      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 .

                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 ?

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

                    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

                      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

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