8 Programming a GUIDE GUI
The following figure shows properties of a push button in the GUID E
Property Inspector prior to saving the GUI. GUIDE set the
Tag property
to
pushbutton1. Before saving the G U I, Callback property displays as
%automatic, indicating that GUIDE will generate a name for it when you
save the GUI.
Note If you change the string %automatic before saving the GUI, GUIDE
does not automatically add a callback for that component or menu item. It is
up to you to provide a callback yourself. That callback has to be the same as
the string you enter.
