First of all, I think you should use a togglebutton, as with a pushbutton the edit box would go invisible as soon as you let go of the mouse button.
for the button callback:
if get(hObject,'Value')
set(handles.editTag,'Visible','On')
else
set(handles.editTag,'Visible','Off')
end
Where editTag is the Tag of your edit button (The default is edit1)
