Thank you for answering!

QAction is not a QWidget and has no palette.

You are right, I am a bad designer. These disabled options are risky to use
and I want the user specifically to enable them from Settings menu. That is
the reason. And I want the user to know that he can enable the item.  
If he clicks on a disabled item, he will get a message box explaining  
that he needs to activate the option.
