fired.
Parameters:
l - Listener to add |
| collapseAll | | void collapseAll()(Code) | | Collapses all nodes of the tree.
|
| collapseNode | | void collapseNode(TreeNode node)(Code) | | Collapses the given node.
Parameters:
node - Node to collapse |
| expandAll | | void expandAll()(Code) | | Expands all nodes of the tree.
|
| expandNode | | void expandNode(TreeNode node)(Code) | | Expands the given node.
Parameters:
node - Node to expand |
| getSelectedNodes | | Collection getSelectedNodes()(Code) | | Returns the collection of all selected nodes.
The collection of selected nodes |
| isAllowSelectMultiple | | boolean isAllowSelectMultiple()(Code) | | Returns whether multiple nodes can be selected.
True if mutliple nodes can be selected |
| isNodeExpanded | | boolean isNodeExpanded(TreeNode node)(Code) | | Returns true if the given node is expanded.
Parameters:
node - The node to inspect True if the node is expanded |
| isNodeSelected | | boolean isNodeSelected(TreeNode node)(Code) | | Returns true if the given node is selected, false otherwise.

node - The node to inspect True if the node is selected |
| removeTreeStateListener | | void removeTreeStateListener(ITreeStateListener l)(Code) | | Removes a tree state listener.
Parameters:
l - The listener to remove |
| selectNode | | void selectNode(TreeNode node, boolean selected)(Code) | | Marks given node as selected (or unselected) according to the selected
value.
If tree is in single selection mode and a new node is selected, old node
is automatically unselected (and the event is fired on listeners).
