Modify Knob From App Designer
显示 更早的评论
How can I modify the Knob from code-wiew in the App Designer through a callback, for example I would like to set the fixed values of the knob only multiples of 2 (example: 2 ^ 1, 2 ^ 2, 2 ^ 3, 2 ^ 4) and the space between them without changing their numerical value.

Sossio - I suspect that you will want to create a discrete uiknob. Perhaps something like the following will do
fig = uifigure;
kb = uiknob(fig, 'discrete');
kb.Items = split(num2str(2.^[1:4]));
kb.ItemsData = {2 4 8 16};
The above simplifies (somewhat) what you want to do as you would want to access the kb via the App object (I'm guessing) in whatever callback you wish to make this change.

I have to do the same thing with the slider, is it possible with the same code?

Perhaps https://www.mathworks.com/matlabcentral/answers/446323-how-to-enable-snap-to-tick-for-a-slider-in-app-designer will provide an idea of what you can do.
