Hi, i am doing a simple GUI now. i don't know how to detect cancel button or cross button is pressed by user for inputdlg , i only know how to do it in questdlg,

eg. ~strcmpi(handles.quest,'OK')

Thanks a lot.

You could do this by checking whether the output of the function is empty:

answer = inputdlg('enter your name');
user_cancelled = isempty(answer);

will it still work, because i set a default value for the input. What i want is to use the default value when i press cancel button or close the input dialog. If i click the OK button, the value(either default value or entered value) will be used.
