How to Disable Button in Dialog Box

Hello

btnOpt_1 = 'Collect new data';
btnOpt_2 = 'Use saved data';

answer = questdlg('Please choose data source :' , 'FilterWheel' , btnOpt_1 , btnOpt_2 , btnOpt_2);

I want my btnOpt_1 to be Disabled (grayed-out). How can this be done?

THANK YOU!

You cannot disable a button using questdlg function. The only thing you can do is to remove the option.

If you do want a grayed-out button, build your own GUI, I can help you if you need help on this point, just ask in comment.

That would be great. Could you show me how to prepare a simple question box with 2 buttons, where I can enable/disable the buttons.

THANKS!!!

What is your MATLAB release ? If R2016a or older you have to use GUIDE components (figure), otherwise go for App Designer components (uifigure).

R2015a.

could you send me the code for GUIDE components?

[Arthur Roué]

If you launch GUIDE (write guide in command window), one of the template is a modal question dialog box.

You can start with this example, and correct the code as you wish.
