I do not know how to do this. I have an AreaPane which has a ChildPaneStyle of Tab which has 2 tabs in. That works well. Now I want to add another controlPane in the same Areapane but dock to the top. I could not seem to find a way to do that. I tried to change the ChildPaneStyle to horizontal split but it applies to all controlPanes in the areapane and got rid of my original tabs. Any hints?
I figured it out. I can use DockableGroupPane to acheive this.
