questdlg

Hi, I'm using questdlg command for asking whether to continue or stop the process. However I don't know how to specify the stop command

here is my code

selection = questdlg('1% Breakthrough has not reached','Continue?','Yes','No','Yes');

>>switch selection,
>>case 'Yes'
>>%let the program run, I leave it blank so it does nothing and continue to run
>>case 'No'
>>%how to stop the function ---> ?
>>end

FYI,I'm calling the function through GUI and the above code is not in the GUI m-files i.e. it's inside the function which is called from GUI. Thank you.

Generally speaking, you would

return

in the function. You might want to explicitly set some output variables before returning.

Inserting a "return" belongs to "Jedi tricks".

How is this function running? Does it just take a while? Is it in a while-loop? If it operated by a timer?

If it's operated by a timer this problem is very easy since you can just stop the timer. Else we have to know more about the function.

Here's code snippet I often start with:

message = sprintf('Do you want to continue');
button = questdlg(message, 'Continue?', 'Yes', 'No', 'Yes');
drawnow;  % Refresh screen to get rid of dialog box remnants.
if strcmpi(button, 'No')
   return; % or break or continue, whatever you need.
end
