linking function and GUI

Hi all

I want to run a function by clicking a push button and display comment of that function in a text box.How can I do that?

I used set(handles.t1,'String','comment') in that function, but matlab returned error "??? Undefined variable "handles" or class "handles.t1"."

handles = guidata(gcf);

Or, alternately, pass handles in to the function in the callback:

..., 'Callback', {@YourFunction,handles}, ...

and adjust the arguments of YourFunction to receive handles .
