Method Detail

computeFullBounds

public PBounds computeFullBounds(PBounds dstBounds)

Computes the full bounds and stores them in dstBounds, if dstBounds is null, create a new Bounds and returns it.

Overrides:

computeFullBounds in class PNode

Parameters:

dstBounds - output parameter where computed bounds will be stored

Returns:

the computed full bounds

repaintFrom

public void repaintFrom(PBounds localBounds,
               PNode childOrThis)

Callback that receives notification of repaint requests from nodes in this node's tree.

Overrides:

repaintFrom in class PNode

Parameters:

localBounds - region in local coordinations the needs repainting

childOrThis - the node that emitted the repaint notification

paint

protected void paint(PPaintContext paintContext)

Paint's this node as a solid rectangle if paint is provided, clipping appropriately.

Overrides:

paint in class PPath

Parameters:

paintContext - context into which this node will be painted

paintAfterChildren

protected void paintAfterChildren(PPaintContext paintContext)

Paints a border around this node if it has a stroke and stroke paint provided.

Overrides:

paintAfterChildren in class PNode

Parameters:

paintContext - context into which the border will be drawn

fullPick

public boolean fullPick(PPickPath pickPath)

Try to pick this node and all of its descendants if they are visible in the clipping region.

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 descendants was picked.
