Problem with function waitforbuttonpress

Hi,

I wrote a code which includes a function 'waitforbuttonpress'. The problem is sometimes (not always), it shows me an error code

    waitforbuttonpress exit because target figure has been deleted

How do I fix this issue?

Hi Min,

Can you please check if the figure corresponding to the callback exist at the time the error comes? This usually happens when the callback is made and the figure corresponding to it was deleted somehow before that.

Thanks

Nikhil
