Configuring static tree navigation panels
As a child of the rtvLayout element, you can specify one or more rtvTreePanel elements. An rtvTreePanel element creates a panel that contains a static navigation tree. The navigation tree assumes there is a panel in the center region that was created with the rtvDisplayPanel element. The static navigation tree sends its navigation commands to this center panel.
There are two ways to create a tree-driven, multi-panel application: the static tree navigation panel and the tree control. Use a static tree navigation panel when you know the specific sources that are to populate the tree and they remain constant for the life of the application. For example, if you know all the displays that compose your application and the static representation of a tree will be used only for navigating those displays the static tree navigation panel is suitable, as well as easier to configure.
Use the tree control when the number of tree nodes, leaves, labels, or icons changes during the lifetime of the application. Data can be provided that will change the nodes and leaves of the tree and also change the label and icon representation on the tree with dynamic data. See Using tree controls in panel displays.
Use the following attributes to specify the location of a static tree navigation panel:
*region - Specify the position of the panel as west, east, center, north, or south. The default is center.
*width - Specify the width of the panel in pixels. The default is 125.
