MatLab GUI Question: Make non-editable textboxes

Hi guys,

I have a test GUI code below (from a .m file which I got when I used the GUIDE wizard). Is there a way to make the textbox on the right be a "non-editable" field, and just be a field where I am able to output a value and not allow user to edit it?

Thank you

function varargout = TestInterface(varargin)
% TESTINTERFACE Application M-file for TestInterface.fig
%   TESTINTERFACE, by itself, creates a new TESTINTERFACE or raises the existing
%   singleton*.
%
%   H = TESTINTERFACE returns the handle to a new TESTINTERFACE or the handle to
%   the existing singleton*.
%
%   TESTINTERFACE('CALLBACK',hObject,eventData,handles,...) calls the local
%   function named CALLBACK in TESTINTERFACE.M with the given input arguments.
%
%   TESTINTERFACE('Property','Value',...) creates a new TESTINTERFACE or raises the
%   existing singleton*.  Starting from the left, property value pairs are
%   applied to the GUI before two_axes_OpeningFunction gets called.  An
%   unrecognized property name or invalid value makes property application
%   stop.  All inputs are passed to TestInterface_OpeningFcn via varargin.
%
%   *See GUI Options - GUI allows only one instance to run (singleton).

Yes, if you set a uicontrol('Style','text') to 'Enable', 'disable' then it will remain but will not be editable.
