I override Sheet.close in my Sheet dialog classes, so that I can take
appropriate action when they are closed or canceled, which happens outside
of my control when user presses Enter or Esc. When I run this in the
debugger, I can see that my close override gets called when the user presses
Esc (call from TerraSheetSkin.keyPressed), and then again when the
sheet-closing animation finishes
(from TerraSheetSkin$4.transitionCompleted). If I want to run some code
when the dialog closes, do I have to keep track of this myself and set a
flag or something? Or is there a better place I can hook into all the
places that terminate the dialog but get called only once?
