First, please use the right tag to mark your code.
Second, in your code you have pointers like dlg and dialog, I suspect this is an error rewriting your code for your post. What happens if you call exec on the dialog?

How do i call the exec on the dialog?? Not able to figure it out.

You can use follow:

or

Sory i mean:

Doesn’t calling exec() on a QDialog (-subclass) always result in a modal dialog? The setModel(true) call seems superfluous to me. You need to call show() if you want the dialog to pop up non-modally.

Andre is right. exec() on a dialog always shows it application model (default) or window modal. A call to setModel is not necessary.

Thanks, I’ll remember.
