BorderPanel

A controller that hosts up to 5 other controllers in a "border" layout.

Here's an example:

Controller: BorderPanel

  WestView:
    DisplayLabel: Navigation
    Controller: BorderPanel
      Width: 155
      Collapsible: True
      Border: True
      Split: True
      NorthView:
        Controller: HtmlPanel
          Split: False
          Html: <p><img src="%IMAGE(kitto_logo_150)%" width="150" height="47"></img></p>
      CenterView:
        Controller: TreePanel
          TreeView: MainMenu

  CenterView:
    Controller: TabPanel
      Border: True
      SubViews:
        View: Girls
        View: Dolls

  NorthView:
    Controller: ToolBar
      TreeView: MainMenu

  SouthView:
    Controller: StatusBar
      Text: <p>User: %Auth:UserName%</p>

And here's the result:

As you can see in the WestView above, each sub-controller can in turn host other controllers, and so on. You can try to "comment" (just add a leading dot or otherwise alter the name) the NorthView and see what happens.
