It's a fairly subtle one. You need to understand that the typical use of QScrollArea is for displaying a large widget in a scrollable area; it assumes that the widget that you give it (via setWidget) will have a size already. Refer to the QScrollArea documentation[1] to see what I mean. To overcome the problem, you can tell the scroll area that it should resize its widget to fill up the available space itself by using the setWidgetResizable function. Therefore, adding the following line after you create the dialog will make things work: self.scrollArea.setWidgetResizable(True) You can also get rid of the scroll area if you don't need it and just call setCentralWidget on your groupDialog class. You could also have done away with the main window altogether and set mainwindow = GroupDialog() in your main block.
