Method Detail

getModel

public DefaultTreeModel getModel()

Overrides:

getModel in class AbstractRearrangeableTreeModel

insertNodes

protected void insertNodes(TreePath pParentPath,
                           Collection<Object> pNodes,
                           int pIdx)

Description copied from class: AbstractRearrangeableTreeModel

Used by rearrangement methods to shuffle nodes around. If rearrangement methods are overridden, a blank implementation will suffice. Implementation may choose to ignore pIdx

Specified by:

insertNodes in class AbstractRearrangeableTreeModel

Parameters:

pParentPath - Path to parent of nodes to be inserted.

pNodes - Nodes to be appended (in order).

pIdx - Index of insertion. May be ignored if model wishes to impose its own node ordering strategy.

removeNodes

protected void removeNodes(TreePath pParentPath,
                           Map<Integer,Object> pNodes)

Description copied from class: AbstractRearrangeableTreeModel

Used by rearrangement methods to shuffle nodes around. If rearrangement methods are overridden, a blank implementation will suffice. pNodes is guaranteed to be sorted in such a way that ordered removal should succeed. That is, indices are in descending order.

Specified by:

removeNodes in class AbstractRearrangeableTreeModel

Parameters:

pParentPath - Path to parent of nodes to be inserted.

pNodes - Map from desired insertion index to node object.

main

public static void main(String[] pArgs)

Opens a window with sample tree and rearrangement buttons.
