whether it is added successfully

addSelectionPaths

boolean addSelectionPaths(int[][] paths)
Adds paths to the current selection. If any of the paths in paths are not currently in the selection the TreeDataListeners are notified. This has no effect if paths is null.

paths - the new paths to add to the current selection

whether it is added successfully

removeSelectionPath

boolean removeSelectionPath(int[] path)
Removes path from the selection. If path is in the selection The TreeDataListeners are notified. This has no effect if path is null.
