Qt + DirectFB not working window drag
-
Hello.
I using Qt embedded 4.8.6 with DirectFB 1.2.8.
I write simple code like below.
#include <QApplication> #include <QMainWindow> int main(int argc, char** argv) { QApplication app(argc, argv); QMainWindow win; win.show(); return app.exec(); }
When I grab window's title bar and drag using my mouse device(for windows move),
my display showing below linked image.https://drive.google.com/file/d/0B8Wbvmr8DTE2MmdiZlVGU3k1eWdEZWNEOVhmbmhZTjBjWUtN/view?usp=sharing
What is wrong?
Thank you.

I found solution and comment for other person.
When I set 'bg-color' to 'transparent(0x00000000)' in .directfbrc,
DFB don't update framebuffer.So, I set bg-color to 'magenta color(0x00FF00FFFF)' in .directfbrc,
and I set colorkey to my framebuffer, it works fine.
