you should write something like this

...
QPixmap pixmap(100, 100);
QPixmap icon("incon.png");
 
QRectF target(10.0, 20.0, 80.0, 60.0);
QRectF source(0.0, 0.0, 70.0, 40.0);
 
QPainter painter(&pixmap);
painter.drawPixmap(target, icon, source);
...

...
QPixmap pixmap(100, 100);
QPixmap icon("incon.png");

QRectF target(10.0, 20.0, 80.0, 60.0);
QRectF source(0.0, 0.0, 70.0, 40.0);

QPainter painter(&pixmap);
painter.drawPixmap(target, icon, source);
...

thanks for your reply


can i set actions for label to display that

Dont mistake me, but do you use Qt Assistant ? or see Qt Demos ?

As for your problem, you could use a QToolButtonor QPushButton, and set the icon when mouse is over it. You will need to subclass them, and as spirit said, override the mouse events.

If you are using label, you could make button as a child of label, and show/hide when the user hovers over a given area. For this too, you will need to subclass QLabel
