How to select and move an image using 1 mouse click?

[Eric Chatonet]

Hi Ian,

Could this code snippet help you:
It's made to move a whole stack but you'll adapt it for an object.

local allowDrag -- variable declared outside any handler
---------------------------------
on mouseDown
   put the mouseH & comma & the mouseV into allowDrag
end mouseDown
---------------------------------
on mouseMove x,y
   if allowDrag is empty then exit mouseMove
   set topLeft of this stack to globalLoc(x - item 1 of allowDrag &  
comma & y - item 2 of allowDrag)
end mouseMove
---------------------------------
on mouseUp
   put empty into allowDrag
end mouseUp
---------------------------------
on mouseRelease
     put empty into allowDrag
end mouseRelease
---------------------------------
on mouseLeave
   put empty into allowDrag
end mouseLeave
