Constraining window dimensions proportionally while resizing

[BNig]

Hi Devin,

I am with Roger on this.

here is a little code snippet that does constrain the aspect after resizing

-----------------------------------------------------------
on resizeStack pNewWidth, pNewHeight, pOldWidth, pOldHeight
   
   -- block repeat loop if you want to have all the changes occur after last
resize, kind of animation
   repeat for each line aMessage in the pendingMessages
      if aMessage contains "adjustRatio" then cancel item 1 of aMessage
   end repeat
   
   send "adJustRatio pNewWidth, pNewHeight, pOldWidth, pOldHeight" to me in
0 milliseconds
end resizeStack

on adJustRatio pNewWidth, pNewHeight, pOldWidth, pOldHeight
   put round (pNewWidth / 2) into tNewHeight
   put the rect of me into tRect
   put item 2 of tRect + tNewHeight into item 4 of tRect
   set the rect of me to tRect
end adJustRatio
-----------------------------------------------------------
