Hi Kenneth,

hmm, I guess that the idea is that user plugins that don't care about
gd.wasCanceled() should also not get the macro interrupted if the user
presses <cancel>.
I fear, however, that plugins that allow the user to press <cancel>, but
to not terminate in that case, will use gd.wasCanceled() anyhow, to
determine whether they should process the dialog input or not.

If you use a dialog in a *macro*, Dialog.show() will check for
gd.wasCanceled(). E.g in the following macro
   Dialog.create("test dialog");
   Dialog.show();
   print("dialog done");
you won't get the 'dialog done' output if the user has pressed <cancel>.

Michael
