Description

Program SAPSIMPLE_TREE_CONTROL_DEMO demonstrates how to use a simple treen control (class CL_GUI_SIMPLE_TREE).

A node of a simple tree control consists of a folder or leaf symbol and a text. Each node is described by the ABAP Dictionary structure TREEV_NODE. To use this structure, you must define a second structure of your own in which you include TREEV_NODE and define a field called 'TEXT'.

Events

The box on the right-hand side of the screen displays events as they occur. The following events can be triggered in the demonstration:

node double click

Double-click on a node.

expand no children

It is possible to make a node display a plus sign in its folder symbol even though it has no child nodes (EXPANDER field set in TREEV_NODE). If the user clicks one of these nodes, the event EXPAND_NC is triggered. In the example, the node "Child1" has this attribute. The program reacts to the event by passing two new nodes to the control (New1 and New2).
