Hello all, I am trying to impliment a GUI for my Calculator program. I have the GUI fully laid out and I am attempting to get my Label to update when I push a button. I am currently trying to get it to work by creating a call back for my button, lets call it Button_1, the button is supposed to set the value of the Label to 1. Any help would be much appriciated, I do not know where to start.

Set the string property in the button callback:
function button1_Callback(hObject, eventdata, handles)
handles.Label.String = '1'; % Whatever

assign a tag to your label, which I assume is a text graphic object.
txt1.Tag = 'label1';
label1.String = 'whateverValue';
