Hi fellow MATLAB users,
I have created a toggle button in a figure programmatically using uicontrol:
tb = uicontrol(gtfig, 'Style', 'togglebutton', 'String', 'Start/Stop', 'tag', 'togglebutton1', 'Position', [30 20 100 30])
How can I get its value after it's pressed? Apparently, the code:
button_state = get(hObject,'Value');
that is used in GUIDE can't be used here. Thank you for your help.

You need to set a callback function for the button if you want something to happen when it is pressed. For example:
% set callback fnuction
set(tb,'Callback',@fun1);
% example for callback function
function fun1(hObject,eventData)
button_state = get(hObject,'Value');
end

It doesn't return anything. Nothing happens when I click on it.
