Dear All,

I have two buttons, each associated with a function callback. When the 1st button is pressed, the code enters a while loop to update a global property. How do I interupt the while loop and exit function 1, when and only when button 2 with its function XButtonPushed(app, event) get activated? In other answers, introducing a small pause or drawnow() should do it (verified that button 1 callback is interruptible, 'on'), but that method is not specific to a certain button (XButtonPushed(app, event)), any button would lead to interruption. How do a specifically instruct 1st callback about a specific button2?

Something like

loopy = true;

while loopy ==true

% do smth

if % button2 pushed,

loopy = false;

continue

end

I tried

if XButtonPushed(app, event) ..., but I get an error about too many output arguments for XButtonPushed.

Thank you,
