[PyQt] Delete a Laytou

[starglider develop]

Hi,
I have a QMainWindow with a main Vertical Layout and  3 HLayouts and several
Widgets in every layout,
but the program needs to remove all the layouts to create another one with a
widget.
How can I remove the original layouts? I was unable to find an answer in the
internet.

Thank you in advance for your help.

Regards
