I am currently creating a GUI for an application and I want to make it frameless and add the minimize and close buttons myself. What I want to achieve can be seen in this answer:
The window structure I want to achieve
Since the GUI structure that I have in mind is really complex I really need that I have to use Qt Designer. Is there a way to achieve what is done in the answer above in the Qt Designer?
One way to achieve this is to create your application window as usual in Qt Designer, load the .ui file in the python via uic.loadUi and add it to the layout of box.contentWidget() instead of the edit in the linked example.
