I am looking for a function like 'Ctrl-C'

Hallo,

I have following problem:

I am working on the Appdesigner and I want to add a 'CancelButton'.

I have two buttons. The first button start a loop (function 'ButtonCallback') and the other button should terminate the execution of the function 'ButtonCallback'. I have already tried:

• exit()
• quite()
• return
• break

I am looking for a function like 'Ctrl-C'.

     set(handle.Button,'Interruptible','on');
     function ButtonCallback(app)
          for i = 1:N
             %statement
             pause(0.00001);
          end
     end

    function CancelButtonCallback(app)
          %Code to terminate the 'Button1Callback(app)' function
     end

thx

You could try using a Java Robot to send a Key Press and Key Release event. However, this is not recommended.

You should be creating your loop to sometimes check a flag indicating whether it is being asked to stop. The cancel button should set the flag.

I do not know enough about app designer to talk about how to create shared values for it.
