Constructor Summary

ZSwing(ZCanvas zbc, javax.swing.JComponent component)
Constructs a new visual component wrapper for the Swing component and adds the Swing component to the SwingWrapper component of the ZCanvas

Method Summary

void	computeBounds() Sets the Swing component's bounds to its preferred bounds unless it already is set to its preferred size.
javax.swing.JComponent	getComponent() Returns the Swing component that this visual component wraps
void	paint(java.awt.Graphics2D g2) Forwards the paint request to the Swing component to paint normally
void	paintAsGreek(java.awt.Graphics2D g2) Paints the Swing component as greek.
void	render(ZRenderContext renderContext) Determines if the Swing component should be rendered normally or as a filled rectangle (Greek?).
void	repaint(ZBounds repaintBounds) Repaint's the specified portion of this visual component Note that the input parameter may be modified as a result of this call.

Field Detail

renderCutoff

protected float renderCutoff

The cutoff at which the Swing component is rendered greek

VISUAL_COMPONENT_KEY

public static final java.lang.String VISUAL_COMPONENT_KEY

Used as a hashtable key for this object in the Swing component's client properties.

Constructor Detail

ZSwing

public ZSwing(ZCanvas zbc,
              javax.swing.JComponent component)

Constructs a new visual component wrapper for the Swing component and adds the Swing component to the SwingWrapper component of the ZCanvas

Parameters:

zbc - The ZCanvas to which the Swing component will be added

component - The swing component to be wrapped

Method Detail

render

public void render(ZRenderContext renderContext)

Determines if the Swing component should be rendered normally or as a filled rectangle (Greek?).

The transform, clip, and composite will be set appropriately when this object is rendered. It is up to this object to restore the transform, clip, and composite of the Graphics2D if this node changes any of them. However, the color, font, and stroke are unspecified by Jazz. This object should set those things if they are used, but they do not need to be restored.

Overrides:

render in class ZVisualComponent

Parameters:

renderContext - Contains information about current render.

paintAsGreek

public void paintAsGreek(java.awt.Graphics2D g2)

Paints the Swing component as greek.

Parameters:

g2 - The graphics used to render the filled rectangle

paint

public void paint(java.awt.Graphics2D g2)

Forwards the paint request to the Swing component to paint normally

Overrides:

paint in class ZVisualComponent

Parameters:

g2 - The graphics this visual component should pass to the Swing component

repaint

public void repaint(ZBounds repaintBounds)

Repaint's the specified portion of this visual component Note that the input parameter may be modified as a result of this call.

Overrides:

repaint in class ZVisualComponent

Parameters:

repaintBounds - The bounding box to repaint within this component

computeBounds

public void computeBounds()

Sets the Swing component's bounds to its preferred bounds unless it already is set to its preferred size. Also updates the visual components copy of these bounds

Overrides:

computeBounds in class ZSceneGraphObject

getComponent

public javax.swing.JComponent getComponent()

Returns the Swing component that this visual component wraps

Returns:

The Swing component that this visual component wraps
