Hi all,
I'm a new guy of directfb, I use dfb+lite to
develop a programe UI.
There is a problem for me to change the opacity of
window by lite_set_window_opacity() function: if the
size of window is big(1024*768) and there are many
objects on window(LiteImage, LiteLabel..), it will
cost a long time(about 100 to 500 ms)for window change
opacity form liteFullWindowOpacity to
liteNoWindowOpacity, is ther any other method to
change window opacity more quickly?
Another question is how to move some objects on
window quickly? Now I destory original objects, change
them rect and new objects, it seems the efficiency of
movement is so bad, could you give me some advice?
Thank you!
yours zhan
