This script seems to work with adequate performance:
on mousemove mh,mv
if the hilite of btn "constrain" is true then
if mh <= the left of fld "container" then
set the screenmouseloc to the globalloc of (the left of fld
"container", mv)
end if
if mh >= the right of fld "container" then
set the screenmouseloc to the globalloc of (the right of fld
"container", mv)
end if
if mv <= the top of fld "container" then
set the screenmouseloc to the globalloc of (mh,the top of fld
"container")
end if
if mv >= the bottom of fld "container" then
set the screenmouseloc to the globalloc of (mh,the bottom of fld
"container")
end if
end if
end mousemove
Note two things:
1) The button "Constrain" needs to be within the field "Container" or you'll
never be able to get out. :-)
2) It is possible to move the mouse out of the rect for brief moments, but
then it pops back into the rectangle. I'm assuming it's a function of
slipping out between a mousemove scan.
