The simplest and most with-the-grain way to do it is to use the messages
the engine is already providing.
So rather than write this:
on resizeStack pWidth,pHeight
myUpdateGeometry
dispatch "refreshChart" to group "netWorthChart"
--pass resizeStack
end resizeStack
... you could write this:
on resizeStack pWidth,pHeight
myUpdateGeometry
set the rect of grp "netWorthChart" to the rect of me
--- ...or whatever rect is desired
end resizeStack
The in the "netWorthChart" group you can trap the resizeControl message:
on resizeControl
refreshChart
end resizeControl
In very old versions of LC (> 4 years old) the resizeControl message was
only sent to objects when they were resized interactively by the user
manipulating the selection handles with the pointer tool.
With the advent of custom controls this was changes some time in the v5
series so that a group can receive the resizeControl message ANY time
it's resized, whether interactively or via script.
Apparently this powerful change to the resizeControl message hasn't made
its way into that Dictionary entry yet, so I just filed a report for that:
