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

[Malyushytsky, Alex]

Or you probably can use QAbstractButton instead of QLabel.
In this case you create Icon from your pixmap for Disabled mode.

I've used it in such way to create custom pixmaps for disabled buttons, when automatically grayed icon is ugly.

Regards,

Alex.

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".
