How to give parent window?

With normal messageboxes you can give it a parent window and the messagebox will stick to the parent at the top. With the current code it goes to the middle. How can I allow the program to not be frozen and stay to the top middle of the window?

Uhh, looks like I missed this issue. It's not possible at the moment, but I'll check it out at some point.

@Moosems maybe you can remove this line:

dialog.wait_window()
