The control displays an object containing a hierarchical list of static items (nodes), such as the headings in a document, the entries in an index, or the files and directories on a disk.
Each node consists of a label and an optional image, where each node can have a list of subitems associated with it. By selecting the tree structure, the user can expand or collapse the associated list of subitems.
R:BASE command syntax can be stored or referenced within the item properties to accomplish a task. The control is ideal for designing menu-driven applications.
The Tree View control now supports the ability to search the nodes for text. This functionality is beneficial to the users where a Tree View contains many nodes with several levels. Pressing [Ctrl] +[F] will display the following search dialog.
The PROPERTY command FINDNODE parameter has also been introduced to allow searching with the command syntax.
Example:
PROPERTY TreeViewControl FINDNODE 'Analysis'
Popup Menu support has been implemented for Tree View and DB Tree View controls, to offer a right click popup menu to run procedures. In the menu item's EEP, use the SelectedID property to capture the right-clicked menu item:
GETPROPERTY DBTreeView1 SelectedID vNodeID
