I did some more experimenting and ended up using a Border component. However,
how do I set the value of something that is in a border? I tried treating it
like any other component eg:
((Border) getBorder()).setSearchText(getSearchText())
but it didn't work. I think the Border component is treated a little
differently to vanilla components?
