Class Overview

Motif rendition of the tree component.

The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. A future release of Swing will provide support for long term persistence.

protected TreeCellRenderer	currentCellRenderer	Renderer that is being used to do the actual cell drawing.
protected int	depthOffset	How much the depth should be offset to properly calculate x locations.
protected Hashtable<TreePath, Boolean>	drawingCache	Used for minimizing the drawing of vertical lines.
protected Component	editingComponent	When editing, this will be the Component that is doing the actual editing.
protected TreePath	editingPath	Path that is being edited.
protected int	editingRow	Row that is being edited.
protected boolean	editorHasDifferentSize	Set to true if the editor has a different size than the renderer.

Public Constructors

public MotifTreeUI ()

creates a UI object to represent a Motif Tree widget

Public Methods

public TreeCellRenderer createDefaultCellRenderer ()

Returns the default cell renderer that is used to do the stamping of each node.

public static ComponentUI createUI (JComponent x)

public void installUI (JComponent c)

Configures the specified component appropriate for the look and feel. This method is invoked when the ComponentUI instance is being installed as the UI delegate on the specified component. This method should completely configure the component for the look and feel, including the following:

Install any default property values for color, fonts, borders, icons, opacity, etc. on the component. Whenever possible, property values initialized by the client program should not be overridden.
Install a LayoutManager on the component if necessary.
Create/add any required sub-components to the component.
Create/install event listeners on the component.
Create/install a PropertyChangeListener on the component in order to detect and respond to component property changes appropriately.
Install keyboard UI (mnemonics, traversal, etc.) on the component.
Initialize any appropriate instance data.

Parameters

c	the component where this UI delegate is being installed

Protected Methods

protected void paintHorizontalLine (Graphics g, JComponent c, int y, int left, int right)

Paints a horizontal line.

protected void paintVerticalLine (Graphics g, JComponent c, int x, int top, int bottom)

Paints a vertical line.
