* A layout that will give one of it's components as much space as possible,

* will in effect be given a fixed sized space, while the space given to the
* expanded component will grow/shrink to fill the rest of the space available -
* for instance when re-sizing the window.
*
* Note that this layout is 100% in both directions by default ({link
* {@link #setSizeFull()}). Remember to set the units if you want to specify a
* fixed size. If the layout fails to show up, check that the parent layout is
* actually giving some space.
