Re: To grab or not to grab

[Matt Denton]

Hi Geoff,

Whoops! Yes bad form, I usually (truly!) use this non-event hogging form (Old HC habits die hard you know...); I guess I was being a lazy typist as I was really looking for an answer on how to drag an object from within a group and have it crop at the boundaries without using the 'grab' form.

Geoff, any clues how I might get an object to stay within the rect of its contained group? I tested the form below (my original code was similar to this) but it doesn't work,

Cheers,

You'd be better off doing something like:

local tDragging -- are we currently dragging?

on mouseDown
   -- check the target here to see if it's what you want
   put true into tDragging
end mouseDown

on mouseMove
   if not tDragging then exit mouseMove
   --move the objects here
end mouseMove

on mouseUp
   put false into tDragging
end mouseUp

on mouseRelease
   put false into tDragging
end mouseRelease

on mouseDown
  if the optionKey is down then
    repeat until the mouse is up
      set the loc of me to the mouseLoc
    end repeat
  else grab me
end mouseDown
