Example 6 with ITreeNode

use of org.eclipse.scout.rt.client.ui.basic.tree.ITreeNode in project scout.rt by eclipse.

the class JsonTree method putChildNodeIndex.

/**
 * If the given node has a parent node, the value for the property "childNodeIndex" is calculated and added to the
 * given JSON object.
 * <p>
 * Note that the calculated value may differ from the model's {@link ITreeNode#getChildNodeIndex()} value! This is
 * because not all model nodes are sent to the UI. The calculated value only counts nodes sent to the UI, e.g. a node
 * with childNodeIndex=50 may result in "childNodeIndex: 3" if 47 of the preceding nodes are filtered.
