[Qt-interest] Drawing A Disabled QLabel Without Graying It

[Nathan Carter]

Can you consider using a QStackedWidget?  Just put the widget on one  
pane, and put that pane on top when you want the widget "enabled"; put  
the image on the other pane, and put that pane on top when you want  
the widget "disabled".
