What Geoff said.


Another way is:




on mouseMove
   if the mouseloc is within the rect of grc 1 then put the mouseColor
end mousemove


The "mouseColor" is a function that works only on the properties of the current mouseLoc. It has one advantage in that it can tell when the mouse is outside the rect, inside the rect, or inside an opaque graphic within that rect.

This works for graphics objects as well, as long as their opaque is true.

within(grc 1,the loc of btn 1) -- true if the point is within the actual
graphic, not just the rect.
