Constructor Summary
`ImageNode()` Constructs a new empty `ImageNode`.

Method Summary
`boolean`	`contains(Point2D p)` Returns true if the specified Point2D is inside the boundary of this node, false otherwise.
`boolean`	`getHitCheckChildren()`
`GraphicsNode`	`getImage()` Returns the graphics node that represents the image.
`Rectangle2D`	`getPrimitiveBounds()` Returns the bounds of the area covered by this node's primitive paint.
`GraphicsNode`	`nodeHitAt(Point2D p)` Returns the GraphicsNode containing point p if this node or one of its children is sensitive to mouse events at p.
`void`	`paint(Graphics2D g2d)` Paints this node.
`void`	`setHitCheckChildren(boolean hitCheckChildren)` If hitCheckChildren is true then nodeHitAt will return child nodes of this image.
`void`	`setImage(GraphicsNode newImage)` Sets the graphics node that represents the image.
`void`	`setVisible(boolean isVisible)` Sets if this node is visible or not depending on the specified value.

Field Detail

hitCheckChildren

protected boolean hitCheckChildren

Constructor Detail

ImageNode

public ImageNode()

Constructs a new empty ImageNode.

Method Detail

setVisible

public void setVisible(boolean isVisible)

Description copied from class: CompositeGraphicsNode

Sets if this node is visible or not depending on the specified value. Don't fire a graphicsNodeChange event because this doesn't really effect us (it effects our children through CSS inheritence).

Specified by:: setVisible in interface GraphicsNode
Overrides:: setVisible in class CompositeGraphicsNode

Parameters:: isVisible - If true this node is visible

getPrimitiveBounds

public Rectangle2D getPrimitiveBounds()

Description copied from class: CompositeGraphicsNode

Returns the bounds of the area covered by this node's primitive paint.

Specified by:: getPrimitiveBounds in interface GraphicsNode
Overrides:: getPrimitiveBounds in class CompositeGraphicsNode

setHitCheckChildren

public void setHitCheckChildren(boolean hitCheckChildren)

If hitCheckChildren is true then nodeHitAt will return child nodes of this image. Otherwise it will only return this node (if the point is in the image).

getHitCheckChildren

public boolean getHitCheckChildren()

paint

public void paint(Graphics2D g2d)

Paints this node.

Specified by:: paint in interface GraphicsNode
Overrides:: paint in class AbstractGraphicsNode

Parameters:: g2d - the Graphics2D to use

contains

public boolean contains(Point2D p)

Returns true if the specified Point2D is inside the boundary of this node, false otherwise.

Specified by:: contains in interface GraphicsNode
Overrides:: contains in class CompositeGraphicsNode

Parameters:: p - the specified Point2D in the user space

nodeHitAt

public GraphicsNode nodeHitAt(Point2D p)

Returns the GraphicsNode containing point p if this node or one of its children is sensitive to mouse events at p.

Specified by:: nodeHitAt in interface GraphicsNode
Overrides:: nodeHitAt in class CompositeGraphicsNode

Parameters:: p - the specified Point2D in the user space

setImage

public void setImage(GraphicsNode newImage)

Sets the graphics node that represents the image.

Parameters:: newImage - the new graphics node that represents the image

getImage

public GraphicsNode getImage()

Returns the graphics node that represents the image.
