Storing Images for use by Custom Controls

[Bob Sneidar]

No sooner said than done. Keep in mind this method depends on four things: 

1. Your main group consists of a number of child groups composed of three controls: a button, an icon image and a disabledIcon image
2. Your button names begin with "btn" and your images begin with "img" eg. "btnNew"
3. Your "icon" images are named like your buttons, excluding the first three characters eg. "imgNew"
4. Your "disabledIcon" images are named like your buttons, excluding the first three characters, and ending in "Disabled" eg. "imgNewDisabled"

on newBackground
   put the childcontrolNames of me into tGroupList
   
   repeat for each line tGroup in tGroupList
      put the childControlNames of group tGroup into tControlList
      filter tControlList with "btn*"
      
      repeat for each line tButtonName in tControlList
         put char 4 to -1 of tButtonName into tControlName
         put "img" & tControlName into tEnabledImage
         put "img" & tControlName into tDisabledImage
         set the icon of button tButtonName to the short id of image tEnabledImage
         set the disabledIcon of button tButtonName to the short id of image tDisabledImage
      end repeat
   end repeat
   pass newBackground
end newBackground

As you can see I have named all my icons in such a way so as to reflect the name of the button itself. If you do that, this could be made into a generic handler that would work for any group with buttons next to their icon images, and you wouldn't need to use literals.
