Method Detail

isSameParent

protected boolean isSameParent(TreePath path1,
                               TreePath path2)

Checks whether two paths have the (immediate) parent. E.g., a.b.c.1 and a.b.c.2 have a.b.c as immediate parent (= true). But a.b.c.1 and a.b.d.2 have only a.b. as parent (= false).

Parameters:

path1 - the first path

path2 - the second path

Returns:

true if paths have the same immediate parent

getSelectionPaths

public TreePath[] getSelectionPaths()

Returns the paths in the selection. This will return null (or an empty array) if nothing is currently selected.

This implemention removes all selection paths that are not on the same level as the first one.

Specified by:

getSelectionPaths in interface TreeSelectionModel

Overrides:

getSelectionPaths in class DefaultTreeSelectionModel

Returns:

the selected paths
