OutlineNode - Reference Documentation
The OutlineNode class provides functions to create an outline tree in the Smart Card Shell.
The Outline can be used to display hierarchical data. A tree consists of nodes represented by instances of the OutlineNode class. You can create nodes, add child nodes, remove nodes and control the behaviour of the tree using action listeners defined for user objects of nodes.
The appearance of a node can be changed dynamically. You can change the label, the icon and set a tool-tip text, which is displayed when the user moves the mouse over the node.
Using the setContextMenu method, you can add context menues to node, which are activated when the user clicks on the node with the right mouse button.
Any actions on the outline performed by the user are delegated to action listener methods implemented by the user object. These methods (expandListener(), collapseListener(), selectedListener() and actionListener()) are activated on their own threads, so long running actions are possible.

Constructor
Prototype
OutlineNode(String name)
OutlineNode(String name, boolean expandable)
Description
Create an OutlineNode object.
The OutlineNode class is not automatically defined and only available in the Smart Card Shell.
OutlineNode objects can receive expandListener(), collapseListener() selectedListener() and actionListener() events from the outline. If such methods are defined in user objects, then they overwrite the expandListener(), collapseListener(), selectedListener() or actionListener() in the OutlineNode object.
Arguments
| Type | Name | Description |
|---|---|---|
String
|
name | Name to show in tree view |
boolean
|
expandable | Show expander for node, even if the OutlineNode has no childs. |
Exceptions
| Name | Value | Description |
|---|---|---|
| GPError | GPError.INVALID_ARGUMENTS | Too many arguments given |
| GPError | GPError.INVALID_TYPE | On or more arguments are not of the expected type |
Example
cnt = 0;
defineClass("de.cardcontact.scdp.scsh3.OutlineNode");
OutlineNode.prototype.expandListener = function() {
print("expand called for " + this );
};
OutlineNode.prototype.selectedListener = function() {
print("selected called for " + this );
};
OutlineNode.prototype.collapseListener = function() {
print("collapse called for " + this );
};
OutlineNode.prototype.actionListener = function(name) {
print("action(" + name + ") called for " + this );
if (name == "add") {
var node = new OutlineNode("node" + cnt, true);
