I have a few questions about drawing on a window (form) using things like .line .circle etc....
1 - Is there anyway to get my lines, circles to show up on screen WITHOUT calling the .refresh function? Also on this line of though, anyway to STOP it from erasing the window when it updates, and only adding in the new lines I drew?
2 - How would I update ONLY a small portion of the screen ( clipping or something like that I think it is called ), when I call refresh, or some other function. Basically I need to update approx 100x100 pixels around the cursor, but right now when I call .refresh on the form, it updates the entire window, and this leads to massive flicker ( and CPU usage I would imagine ).
Thanks for any help
