public class PClip

extends PPath

PClip is a simple node that applies a clip before rendering or picking its children. PClip is a subclass of PPath, the clip applies is the GeneralPath wrapped by its super class. See piccolo/examples ClipExample.

Method Detail

computeFullBounds

public PBounds computeFullBounds(PBounds dstBounds)

Description copied from class: PNode

Compute and return the full bounds of this node. If the dstBounds parameter is not null then it will be used to return the results instead of creating a new PBounds.

Overrides:

computeFullBounds in class PNode

Parameters:

dstBounds - if not null the new bounds will be stored here

Returns:

the full bounds in the parent coordinate system of this node

repaintFrom

public void repaintFrom(PBounds localBounds,
                        PNode childOrThis)

Description copied from class: PNode

Pass the given repaint request up the tree, so that any cameras can invalidate that region on their associated canvas.

Overrides:

repaintFrom in class PNode

Parameters:

localBounds - the bounds to repaint

childOrThis - if childOrThis does not equal this then this nodes transform will be applied to the localBounds param

paint

protected void paint(PPaintContext paintContext)

Description copied from class: PNode

Paint this node behind any of its children nodes. Subclasses that define a different appearance should override this method and paint themselves there.

Overrides:

paint in class PPath

paintAfterChildren

protected void paintAfterChildren(PPaintContext paintContext)

Description copied from class: PNode

Subclasses that wish to do additional painting after their children are painted should override this method and do that painting here.

Overrides:

paintAfterChildren in class PNode

Parameters:

paintContext - the paint context to sue for painting after the children are painted

fullPick

public boolean fullPick(PPickPath pickPath)

Description copied from class: PNode

Try to pick this node and all of its descendents. Most subclasses should not need to override this method. Instead they should override pick or pickAfterChildren.

Overrides:

fullPick in class PNode

Parameters:

pickPath - the pick path to add the node to if its picked

Returns:

true if this node or one of its descendents was picked.
