Main UI Freezes on QFileDilog is up

[navi1084]

I further noticed that, since i am drawing image too, the data's will not update() if i call update(). But if i call repaint() all the data's in the controls, as well as image in the widget is updated.

Can you please tell me which function is blocking from drawing(calling paintEvent()) when modal dialog is executed on the top of main UI.

You are working on Windows? According to docs:

On Windows the dialog will spin a blocking modal event loop that will not dispatch any QTimers,

Is there anyway to avoiding the freeze????

If it really is this problem, you might want to instantiate and configure your file dialog 'manually' and not use the convenient static function.
