Thanks I got the button pretty much how I want it.
But I cannot for the life of me get the dataBrowser to expand to the
left(Horizontal).
I want the dataBrowser to be at the top of the window and expand to the
left when the window is maximized.
I have it in a dataSource and Vpanel as i want to line things up
verticaly.Also have tried a Hpanel without luck, but I cannot figure out
how to get it to expand to the left.

I tried following the example project you sent, but couldn't get my
dataBrowser to expand left, it will only expand down.

How did you get the 'txtWindowLister' and the 'txtDTWatcherEvents' to
expand to the left??
