Re: "within graphic" question
I’ve had this problem before and solved it with a work-around/hack using the
intersect of 2 graphics with small alpha values.

Re: "within graphic" question
If you're willing to do something "hackish", you could do this: on mouseDown lock screen show grc "mygraphic" put within(grc "mygraphic",the clickloc) hide grc "mygraphic" unlock screen end mouseDown :D Ken > On Feb 22, 2021, at 1:49 PM, jbv via use-livecode > wrote: > > Hi list, > > I have a graphic made of a list of points.

I missed the part where you described your graphic. My solution will only work
on a graphic that is a rectangle.

Since the properties of the arc is available even if it is invisible, this will
work though:
on mouseDown
put isWithin("myGraphic",the clickLoc)
end mouseDown
function isWithin pGraphic pClickLoc
if pClickLoc is within the rect of grc pGraphic then
return true
else
return false
end if
end isWithin

Re: "within graphic" question
Would it work in your case if you left the graphic visible and set the blendLevel to 99? be well, randy > On Feb 22, 2021, at 2:14 PM, Richard Gaskin via use-livecode > wrote: > > jbv wrote: >> I have a graphic made of a list of points.
