Get index of selected button in button toggle group

When using a ButtonGroup in AppDesigner it is not clear how to get the index of the selected button. The only available approach appears to be:

string_values = {h.Buttons.Text};
I = find(strcmp(h.SelectedObject.Text,string_values));

Is there anything more direct?

I don't think so, but I don't immediately see why you would want to assign numeric indices to the different buttons. Processing the selection would normally be done index-free using a switch...case

switch h.SelectedObject.Text

    case 'Button #1'

    case 'Button #2'

end

If you want to associate selections with numeric values, a slider or spinner would be a more appropriate component.

I still don't think this is the best way, but you can cycle through the buttons in the group with a for loop to check which index has a value of 1 for being pressed down

for i = 1:buttonGroupSize
    app.ButtonGroup.Buttons(i).Value
end
