Flush / update GUIs in PyQt5 during debugging in PyCharm

[Mohsen Owzar]

Hi Guys
I've written a GUI using PyQt5 and in there I use StyleSheets (css) for the buttons and labels to change their background- and foreground-colors and their states as well.
Because my program doesn't function correctly, I try to debug it in my IDE (PyCharm).
The problem is that during debugging, when I change some attributes of a button or label, let say its background-color, I can not see this modification of the color until the whole method or function is completed.
I believe that I have seen somewhere during my searches and googling that one can flush or update the GUI after each step/action is done.
But until now I couldn't manage it and I don't know where I have to invoke flush/update command in PyCharm.
If anyone has done this before and knows about it, I would very appreciate seeing his solution.

Regards
Mohsen
