How to set min and max size to SplitLayoutPanel

[BM]

I have following view using UIBinder.

<g:SplitLayoutPanel height="100%">

<g:west size="225.0">

  <g:SimpleLayoutPanel ui:field="adminMenu"/>

</g:west>

<g:center>

  <g:SimpleLayoutPanel ui:field="contentAreaContainer" addStyleNames="contentArea" />

</g:center>

</g:SplitLayoutPanel>

How do I assign a minimum size and maximum size to this spit layout panel that way I can drag only to a certain size left and right?
