How to set the BG color of qMainWindow

[summit]

Currently i am setting the color of the QMainWindow using this line of code.

      w.setStyleSheet("QMainWindow {background: 'lightgrey';}");

How can i set the color by RGB values like (255 , 255 ,255)

Hi,

You can use rgb(255, 255, 255). There's an example here in the documentation.
