What is the KOL equivalent for Application.OnIdle event?
I have a mck form, an imagelist and a paitbox. I have loaded a bitmap picturing a tennis ball.
How can i move the ball on the form"s surface, up and down, if i have no .OnIdle event?
Is there a secret windows message that i can track to get this kind ov eventloop ?

Thanks

RegisterIdleHandler, KOL 1.85+.

But it is possible (and better) to use in OnTimer: PaintBox1.Invalidate;

and move your balls in PaintBox1.OnPaint.

Or even more better to change ball position in OnTimer, and in OnPaint just repaint it.

It is better to use kol Thread object, you can reach maximum posibble redraw speed.
