<h2>7.5: Running it&nbsp;<a href="User_guide7.html"><img src="Images/uparrow.png" border="0" align="top" alt="Go back up one level"/></a></h2>
<p>When the main function is launched (click
<a href="matlab: p=pwd();cd(fullfile(layoutDocRoot,'Examples'));demoBrowser;cd(p)">here</a>)
it first creates the data, then the GUI, then updates the GUI using the data. At this point the
function exits and control is returned to the command prompt. Note, however,
that the GUI is still onscreen and will still respond to user interaction.</p>
<p>This works because the "shared" variables in the main function are not cleared when the
function exits. They are only cleared once the GUI is closed. This is a slightly
unusual, but very useful, feature of using nested functions for building
applications.</p>
<h3>For example:</h3>
<pre style="background-color: #eeeeff; margin-left: 20px; margin-right: 20px"><font color="#000011">&gt;&gt; demoBrowser</font></pre>
<p style="background-color: #ddddee; margin-left: 20px; margin-right: 20px"><font color="#000022"><center><img src="Images/demoBrowser4.png"/></center></font></p>
<p><small>(Full source code for this application is available here:
[ <a href="Examples/demoBrowser.m">view</a>
| <a href="matlab: edit(fullfile(layoutDocRoot,'Examples','demoBrowser.m'))">edit</a>
| <a href="matlab: p=pwd();cd(fullfile(layoutDocRoot,'Examples')); demoBrowser; cd(p)">run</a> ]
