Storing Images for use by Custom Controls

[Simon Knight]

Well I tried using custom props but did not get very far with them.  My solution is to add the image files to the group and hide them behind other controls.  I have added the attached handler that sets the button icons to the values of the images in the group.  The handler should be called when the original control is duplicated but.  

I used the array to ensure that the handler only finds images that are part of the group:

on newgroup
   -- set the icons for the buttons
  
   --build an array of refs to images in the group
   repeat with x=1 to the number of images of me
      put the ID of image x into tID
      put the short name of image x into tName
      put tID into ImageA[tName]
   end repeat
   
   --now set the icons
   set the icon of button "add" of me to ImageA["imgPlus"]
   set the icon of button "SortA" of me to ImageA["imgSort"]
   set the icon of button "Delete" of me to ImageA["imgBin"]
   
   set the icon of button "SortB" of me to ImageA["imgSort"]
   set the icon of button "Remove" of me to ImageA["imgLeftArrow"]
   set the icon of button "Use" of me to ImageA["imgLeftArrow"]   
end newgroup
