I'm looking to have a few checkboxex that change the possible values of a dropdown menu.

For instance:

If checkbox A is selected, then the dropdown options would be X,Y,Z

If Checkbox B is selected, then the dropdown options would be A,B,C

I'm looking to have a switch function power this process and would think that I could assign a value to the selection of each checkbox and have that execute the switch.

I don't know how to get the checkbox data (numerical value) to the dropdown function.

Any help would be great.

在 MATLAB Online 中打开

Try this:

% If checkbox A is selected, then the dropdown options would be X,Y,Z
if handles.checkboxA.Value
    handles.dropdown.String = {'X', 'Y', 'Z'};
end
% If Checkbox B is selected, then the dropdown options would be A,B,C
if handles.checkboxB.Value
    handles.dropdown.String = {'A', 'B', 'C'};
end
