Syntax

on openDrop
  ...
end openDrop

Explanation

This message is sent the first time the user picks up something in another window (or possibly even another application) and dragged it over a window in SuperCard. You can e.g. examinee the dragged data and cache information about it.

You can then use that information in mouseDrop/mouseDropEnter/mouseDropLeave and clean it up when you get the corresponding closeDrop message.
