Nested Class Summary

static class

CompositeHighlighter.HighlightingMode Local highlighting mode corresponding to each Element in the parent BranchElement being highlighted Global highlighting mode corresponding to the 8 outer control-points being highlighted

Field Summary

protected CompositeHighlighter.HighlightingMode

highlightingMode highlight mode (default to GLOBAL)

Fields inherited from class jpicedt.graphic.view.highlighter.DefaultHighlighter

bounds, element, factory, pointIndexIterator, ptBuffer, rectBuffer, shape

Constructor Summary

CompositeHighlighter(BranchElement e, DefaultHighlighterFactory f)
construct a new Highlighter for the given BranchElement.

Method Summary

BranchElement	getElement() returns the higlighted Element
CompositeHighlighter.HighlightingMode	getHighlightingMode() Return the current highlighting mode.
HitInfo	hitTest(PEMouseEvent e) Returns a HitInfo corresponding to the given mouse-event.
boolean	intersect(Rectangle2D r, ArrayList<Element> list) If this highligher intersects the given rectangle, add the associated BranchElement (or a child Element thereof if it's more appropriate) and returns true.
void	paint(Graphics2D g, Rectangle2D allocation, double scale) Render the Highlighter to the given graphic context.
void	setHighlightingMode(CompositeHighlighter.HighlightingMode mode) set the current highlighting mode ; this influences the way the Highligther is painted, but also the result returned by HitTest.
protected void	syncShape(double scale) Synchronize the array of "shapes" needed to paint this highlighter, with the model ;
void	toggleHighlightingMode() Toggle the current highlighting mode.

Constructor Detail

CompositeHighlighter

public CompositeHighlighter(BranchElement e,
                            DefaultHighlighterFactory f)

construct a new Highlighter for the given BranchElement.

Method Detail

getElement

public BranchElement getElement()

Description copied from interface: Highlighter

returns the higlighted Element

Specified by:

getElement in interface Highlighter

Overrides:

getElement in class DefaultHighlighter

Returns:

the higlighted Element.

setHighlightingMode

public void setHighlightingMode(CompositeHighlighter.HighlightingMode mode)

set the current highlighting mode ; this influences the way the Highligther is painted, but also the result returned by HitTest.

Parameters:

mode - either LOCAL_MODE or GLOBAL_MODE

getHighlightingMode

public CompositeHighlighter.HighlightingMode getHighlightingMode()

Return the current highlighting mode.

toggleHighlightingMode

public void toggleHighlightingMode()

Toggle the current highlighting mode.

syncShape

protected void syncShape(double scale)

Synchronize the array of "shapes" needed to paint this highlighter, with the model ;

Overrides:

syncShape in class DefaultHighlighter

Parameters:

scale - The current scale factor from-model-to-screen for the Graphics2D context ; this may be used to scale down line thickess, etc… so that e.g. barbells appear with the same size on the screen whatever the scale factor being set to the graphic context.

paint

public void paint(Graphics2D g,
                  Rectangle2D allocation,
                  double scale)

Render the Highlighter to the given graphic context.
In GLOBAL mode, only the 8 control-points are rendered, whereas in LOCAL mode, only children's highlighters are rendered.

Specified by:

paint in interface Highlighter

Overrides:

paint in class DefaultHighlighter

allocation - current clipping

scale - The current scale factor from-model-to-screen for the Graphics2D context ; this may be used to scale down line thickess, etc… so that e.g. barbells appear with the same size on the screen whatever the scale factor being set to the graphic context.

hitTest

public HitInfo hitTest(PEMouseEvent e)

Returns a HitInfo corresponding to the given mouse-event. In GLOBAL mode, hit test occurs on the 8 control-points and the highlighter's stroke, while in LOCAL mode, it occurs on the children's view and highlighter. Note that in the latter case, the returned HitInfo is the same as the one given by invoking hitTest() directly on the corresponding child (i.e., no HitInfo.Composite is returned whatsoever).

Specified by:

hitTest in interface Highlighter

Overrides:

hitTest in class DefaultHighlighter

Returns:

a HitInfo corresponding to the given mouse-event

intersect

public boolean intersect(Rectangle2D r,
                         ArrayList<Element> list)

If this highligher intersects the given rectangle, add the associated BranchElement (or a child Element thereof if it's more appropriate) and returns true.

Specified by:

intersect in interface Highlighter

Overrides:

intersect in class DefaultHighlighter
