 |
|
Hi all,
I've tried to find the answer to this through google, but haven't had
any success. Anyway, I have a experiment almost done which presents a
random stimulus at the top of the screen with 3 different response
option available. I'm trying to get the paintbox to display a new
randomly drawn stimulus using the code I have that is triggered by the
onpaint event for the paintbox. So far, I've been unsuccessful. I've
solved the errors with the following code:
FTrial.PaintBox1.Canvas.Create;
but I don't think that'll shoot off my stimulus-drawing code. Any ideas
on how I can do it?
Josh

If you don't _think_ it will repaint the paintbox, what error did you
solve?
Try Invalidate.
Groetjes,
