Yes i know :D,, excuse me for the late reply by the way...
anyways, something was just bugging out.. because even if i added the image in the ui designer, it would show it in the designer... but as soon as i compiled and ran the program, the background would be gone...
which is really weird, because if the designer shows the background image correctly, then that means the url and everything is correct...
and even after that, i run the program and the background is just gone... like some kind of dark magic
