I can click the 'cancel' button, and the UI reacts (the message above the barber pole changes to
"Canceling") but LiveCode doesn't, and I can't figure out where I'd see in code that the
user is pressing it. (On the other hand I also can't use command-period to halt
the<cough>buggy</cough> script, presumably because the 'printing in progress' dialog
catches the keyboard event.)
Mark,
Thanks for responding. I don't think I can post my script - it's currently a
hideous mess of fragments and bits (because of course I never have bugs in my
code once I move beyond that stage!).
But essentially it does 'open printing with dialog', then goes into a big loop
in which it executes various 'print card from ... into rect' and 'print break'
commands; finally it executes 'close printing'.
Immediately after the call to 'open printing with dialog', my code can check
whether the the user clicked 'cancel' on that. But from then until 'close
printing', there's a printing progress dialog up, on which the user can click
'cancel'; but I can't see a way to find out that they've clicked it; meanwhile
because the dialog is there, they can't interact with my stack, so I can't
give them any way to cancel the job.
Do you have a way to discover that the user has clicked cancel?
TIA,
Ben
