The explorer-style (or tree) applet presents hierarchically structured information in an expandable tree control. The tree control is displayed in a frame on the left side of the applet content area. Detailed information for a selected tree node is displayed in the details applet in a frame to the right. The separate vertical frames allow the contents of the tree applet to be scrolled independently from the details applet. This is important because tree structures can typically grow very large in length and width.
A tree control can have repository tree nodes and field values as elements in the tree. The term "tree item" refers to a tree element regardless of its type. A repository tree node is called a "tree node."
Each tree item is indented to place the text at the correct indent level relative to the root, and to display the expand/collapse button, the text of the item, and the hyperlinks. The indentation is accomplished using a series of GIF images, or just white spaces (when in text-only mode). The expand/collapse button and the item are displayed using images (or just text, in text-only mode). The list applet associated with the currently selected tree node is displayed as part of the view.
Iterates over each visible item in the tree control in a top-down, "depth-first" fashion. This tag is used to display tree nodes and field values. If "count" is not specified, the tag iterates over all nodes in the tree.
Provides a placeholder for a GIF image corresponding to a tree item's current indentation level. At each level, SWE determines which GIF file to use in the
Provides a placeholder for an item in the tree. A tree item can be a repository tree node or a field value. The display name is printed if the tree item is a tree node. Otherwise, the field value is generated. The expand/collapse button, the item's icon, and the links are also parts of a tree item. Depending on the configuration file settings, the expand/collapse button is shown as either a GIF image or text. The expand/collapse button is only shown for tree items with child items. There are two links associated with each item. There is a link for the expand/collapse button to expand or collapse the item and a link for the item image for selecting the item (or for going to next or previous workset). The item selection allows the user to access the list applet associated with the tree node. This tag should use
