prajna.viz.display.FillTreePane<N>

Type Parameters:

N - The node type for the tree

All Implemented Interfaces:

public class FillTreePane<N>
extends javax.swing.JPanel
implements TreeDisplay<N>

Implementation of a Tree display using rectangular tiles to represent each node. This tree display is roughly based upon the TreeMap displays from the University of Maryland.

The FillTreePane is a recursive container; child nodes are added as FillTreePanes to the parent pane. The direction of the grid (horizontal or vertical) alternates at each level.

Constructor Detail

FillTreePane

public FillTreePane(Tree<N> node)

Create a FillTreePane with the specified node as the root node for the pane, using a horizontal orientation.

Parameters:

node - the node to display

FillTreePane

public FillTreePane(Tree<N> node,
            boolean isHorizontal)

Create a FillTreePane with the specified node as the root node for the pane, and in the specified orientation.

Parameters:

node - the node to display

isHorizontal - true if the child nodes should be arranged in a horizontal arrangement, false otherwise.

Method Detail

addItemListener

public void addItemListener(java.awt.event.ItemListener listener)

Adds a listener which will receive any ItemSelected events. An ItemSelected event is generated whenever a node or edge is selected or deselected.

Specified by:

addItemListener in interface java.awt.ItemSelectable

Parameters:

listener - the ItemListener to receive node or edge selections

fireItemStateChanged

protected void fireItemStateChanged(java.awt.event.ItemEvent event)

Notifies all listeners that have registered interest for notification on this event type.

Parameters:

event - the ItemEvent object, indicating node/edge selection

getSelectedNode

public N getSelectedNode()

Get the currently selected node. Because of the recursive nature of the FillTreePane, this method will return null if the selected node is not this pane's root node or a child of the root node.

Specified by:

getSelectedNode in interface TreeDisplay<N>

Returns:

the selected node, or null

getSelectedObjects

public java.lang.Object[] getSelectedObjects()

Returns the selected items or null if no items are selected.

Specified by:

getSelectedObjects in interface java.awt.ItemSelectable

Returns:

the list of selected objects

getTree

public Tree<N> getTree()

Get the root of this FillTreePane. In this case, this method simply returns the node associated with this FillTreePane.

Specified by:

getTree in interface TreeDisplay<N>

Returns:

the root node of this FillTreePane

processMouseEvent

protected void processMouseEvent(java.awt.event.MouseEvent event)

Process a MouseEvent on this pane. This method is used to handle selection of the pane and child panes.

Overrides:

processMouseEvent in class javax.swing.JComponent

Parameters:

event - the MouseEvent to process.

removeItemListener

public void removeItemListener(java.awt.event.ItemListener listener)

Removes the ItemListener from the list of listeners receiving the node or edge selection events

Specified by:

removeItemListener in interface java.awt.ItemSelectable

Parameters:

listener - the ItemListener to remove

selectNode

public void selectNode(N node)

Set the selected node on the display. The selected node will be drawn with a highlight around it.

Specified by:

selectNode in interface TreeDisplay<N>

Parameters:

node - the node to select

setTree

public void setTree(Tree<N> newTree)

Set the root node for this FillTreePane. In this case, the display is regenerated with the new node and its children replacing the old one in the pane display

Specified by:

setTree in interface TreeDisplay<N>

Parameters:

newTree - the new root node for this Pane.

updateTree

public void updateTree()

Reload the tree model. This forces the FillTreePane to reload the tree, regenerating any new children which have been added to the tree display.

Specified by:

updateTree in interface TreeDisplay<N>
