title: Single- and Multi-line Edit Controls
body: <p>I'm writing a GUI in GUIDE but when I open it and when I perform an action I keep getting this warning:</p>
  
  <pre><code>Warning: Single line Edit Controls can not have multi-line text 
  &gt; In openfig at 135
    In gui_mainfcn&gt;local_openfig at 286
    In gui_mainfcn at 234
    In Var_final at 42 
  Warning: Single line Edit Controls can not have multi-line text 
  Warning: Single line Edit Controls can not have multi-line text 
  </code></pre>
  
  <p>Is it a problem? I've read you need to set the <code>Max</code> value to 2, but the warnings seem to persist.</p>
  
  <p>What can I do?</p>
