Returns whether the given path is currently checked.

isPartiallyChecked

public boolean isPartiallyChecked(TreePath path)

toggleChecked

public void toggleChecked(int row)

getCheckedRows

public int[] getCheckedRows()

Returns all checked rows.

getCheckedPaths

public TreePath[] getCheckedPaths()

Returns all checked paths.
