hi, when i execute my app designer script by 1 click its doing well.

but when i spam the button or just double clicking it, it's execute the callback multiple times or maybe sometimes causing a error for running more that once the callback code.

my question is if there is something to ignore this multiple click on the button and execute the callback function just once.

thanks.

Is the user supposed to click that button only once during the entire run time of the app?

If so you can add a line of code to disable the button just after it is pushed, before the rest of the code of the callback:

function PushButtonPushed(app, event)
    app.PushButton.enable = 'off' 
    % Other stuff
end

Then, whenever you want to bring it back to life just set the flag to on.

hi thanks for answering.

i already try your suggestion, the problem is when im like spamming the button, the button not disable himself that fast and he still have a lot of calls to the callback function

is there any wat to cancel the calls for the callback after one click?
