How can I fix this Layout Allignment?

[E-ray96]

Hey Guys,

As shown in the screenshot, you can see that I still have significant gaps at the indicated locations (red arrows) that I can't get rid of.

I positioned all QGroupBox widgets using the "Layout in a Grid" function. In the QGroupBox widget "Project Management," I additionally added a "TreeWidget" and a button.
I also positioned the QGroupBox widget "Project Management" and all its contents using the "Layout in a Grid" function.

Thank you in advance :)

@E-ray96 Add layout to your QGroupBox just like its documentation shows.
