I'm working on seekbar. then I found out skipping repaint();
In on_timer() function , called window.RepaintRect() or window.Repaint(), but It didn't repaint in no burden program is running.
for checking, use code " bar.test = <value>; " in on_timer function, and reset variable " bar.test = 0;" in on_paint function.
next recursive on_timer function, check bar.test is empty with " if (bar.test) echo("error"); "
within playing a song, lots of error was printed in console.
there is other window.RepaintRect(..); code in on_playback_time function. but same results popped though make it comment.
Is this a bug? or miss something?
