Event handling |
|
Tree component triggers the following types of the events.
| • | TreeBranchSelectedEvent - if user clicks on the branch of the tree. |
| • | TreeLeafBranchSelectedEvent - if user clicks on the leaf of the tree. |
| • | TreeBranchOpenedEvent - if user clicks on the image to open tree brach (used basicly to implement tree lazy loading). |
| • | TreeBranchClosedEvent - if user clicks on the image to close tree brach. |
These events can be easily handled by implementing TreeBranchSelectedListener, TreeLeafSelectedListener, TreeBranchOpenedListener and TreeBranchClosedListener listeners accordingly.
Note:
serverSideAction tag property must be set to true
treeBranchSelectedListener, treeLeafSelectedListener, treeBranchOpenedListener and treeBranchClosedListener tag properties must contain fully qualified listener class name.
