Inhibit mouse Events possible?

[Mark Schonewille]

Hi Bill,

If you like your own approach, just do what you think is best. I 
discourage such brute force approaches however, because if something 
goes wrong, the only way for the user to get out of the trap is to 
restart the software. My example can be adjusted fairly easily to 
provide a way out:

local lBusy,lSecs
on mouseUp
    if lBusy is true and the optionKey is up then
       beep
       exit mouseUp
    else if lBusy is not true then
       put true into lBusy
       put the seconds into lSecs
       repeat forever with messages
          // some long task here
          if the seconds - lSecs > 5 then exit repeat
          wait 0 millisecs with messages
          if the optionKey is down then exit mouseUp
       end repeat
       put false into lBusy
    else if the optionKey is down then
      put false into lBusy
      // enable disabled controls if any
    end if
end mouseUp

I have multiple buttons on the screen and they each call a number of handlers. I just thought there might be a command to disable mouse messages.

>>> Is it possible to inhibit mouse events? Some of the operations that are initiated by a mouse click require a bit of time and I don’t want the user to be able to click around until each operation is finished. One approach would be to put a transparent rectangle over the stack and not pass events, but I wonder if there is a more direct way.
