title: Gwt VerticalPanel Cell Height
body: <p>I have a horizontalpanel with 3 verticalpanels inside.
  In the verticalpanels there are custom widgets</p>
  
  <p>I need all verticalpanels has the same height (even if they have different number of widgets inside) and a button in the empty space. </p>
  
  <p>So, I put all panels height = 100% and the buttons height = 100%.</p>
  
  <p>The problem is that the verticalpanel cells height are bigger than my widgets, so it left a space between all verticalpanels widgets.</p>
  
  <p><a href="http://dfg-ber1.appspot.com/" rel="nofollow noreferrer">Here is an example</a></p>
  
  <p>How can I adjust the verticalpanels cells height to my widgets height. My widgets are not images like in the example, so i can't know the widgets height.</p>
  
  <p>I have a lot of time in this problem, anyidea will help
  Thx!!!!</p>
