Sounds good -- I'm curious to see what you've done. I was wondering because it looked in your sample like you were using coordinates from your parent panel to calculate coordinates for your FC object -- that's a bit odd, as the point of FC is that your "natural" coordinates are independent of the pixel coords used to actually draw, and even those would be relative to the FC window itself, rather than the parent window. But maybe that was a quick sample to test with... -Chris > Thanks again. > > Saeed > > > On 31 December 2011 04:19, Chris Barker <[email protected]> wrote: >> >> Saeed, >> >> I took a look at your script: >> >> > I can't get the panel color to change in the canvas (in class AREA).
