The AS400TreePane class represents a graphical user interface that presents a tree, where all information for the tree is gathered from the hierarchy of objects rooted at an AS/400 resource. You must explicitly call load() to load the information from the AS/400.
Most errors are reported as ErrorEvents rather than throwing exceptions. Users should listen for ErrorEvents in order to diagnose and recover from error conditions.
AS400TreePane objects generate the following events:
The following example creates a tree pane filled with the contents of a directory in the integrated file system of an AS/400.
// Set up the tree pane. AS400 system = new AS400 ("MySystem", "Userid", "Password"); VIFSDirectory directory = new VIFSDirectory (system, "/myDirectory"); AS400TreePane treePane = new AS400TreePane (directory); treePane.load ();
// Add the tree pane to a frame. JFrame frame = new JFrame ("My Window"); frame.getContentPane().add (treePane);
