Is there a specific function forcing user to select a particular option?
显示 更早的评论
Hi,
I want to force user to select a particular option in a console program.
For example, the script might ask which pet does the user have and force him to type cat, dog, bird or other. Is there a specific function for this? Such as:
a_fancy_function('Which pet do you have? (cat, dog, bird, other)', 'cat','dog','bird','other');
Thank you.

It is the only graphics function that I can think of that is simulated as text when there is no graphics. An oddity that is easily forgotten.

Hi,
no, for a console program there is no function for this. You will need to use the function input and verify what has been typed by the user (in a while loop with e.g. three attempts at most).
For a non console program you can use listdlg.

you can use
i= menu(' Which Pet do You Have?','cat','dog','bird','other');
Which results in a pop up menu with options which returns the values for i as
i=1 if cat is selected.. i=2 if dog is selected.. i=3 if bird is selected.. 1=4 for other ..

This works differently on a console program, as it does not pop-up if there are no graphics. It will, however, happen to work, as menu() detects the lack of graphics and uses a text prompt instead. This is as shown in example 2 of the documentation for menu(), as I indicated in my answer.

Yeah, i fully agree with you. I tried out in console program and found not working. Thanks for the information.
