Brilliant - covers [nearly] all the essential points. Enough info so I could add a Quit menu action and change CSS text color on QMenu. Not only is this clearly presented in an orderly manner, there is very little fluff or diversion. Much appreciated - thank you. BTW icons on a toolbar might be an interesting addition.

Hi Hala
Can you make a tutorial on how to make our PYQT5 app responsive to different screen size?

[pdep]

Hmm - sorry to say I may have found an 'issue' - when part of text have a font size is increased and the file then saved, the increased [or decreased] font sizes are not preserved. They revert to a common fontesize. Any suggestions. please?

Thanks for the video! There is anyway or anywhere to know all possible styleSheet parameters for every widget in QtDesigner?

Which one will be better. Qt C++ or Qt with python.
