Transparent background with linuxfb
I'm trying to overlay animation with QT using linuxfb. I'd like to have it set up so that when QT redraws the image, it clears the background to Qt::transparent. Anything I have tried so far simply results in either a black or white rectangle, but not a "clear" one.
All QT has to do is write 0x00000000 to each pixel, but I can't quite seem to figure out how to make it do that. Any advice?
I can change the background color (setBackgroundBrush) to anything I want, but I can't make it transparent. What am I doing wrong?
I managed to set the background to transparent, but for some reason, QT never draws the background. Obiously this is terrible for animation. I want it to always draw the background, but draw a transparent background. Any ideas?
I have determind that this is NOT possible. It's a good idea to move to the eglfs or minimalegl platform.
