background for images with alpha channel
I’m making an image viewer, and i have made it shows animated images, but i can’t find the way to set the background for those that have an alpha channel. It’s easy to make it with static images, using qpainter, but i don’t know how to do it with animated images.
by the way, i’m learning both Qt and english, so please be patient :-P
So, I think Vass meant to overwrite paintEvent [doc.qt.nokia.com] and do the painting by yourselve instead of let QImageLabel do the painting for you.
Gerolf It seems to me what I with you said about different things. As I understand samkpo has movie with alpha channel, and He want set background under this movie. You said about animate background for something with use Qmovie.
But then you can just paint the background beffore drawing the move:
Or position a label or widget with the needed background exactly below the imageLabel. (so position one widget with setgeometry or make obne label a child of the other one). Or does QLabel not draw the movie with transparent background?
