protected TextLayoutFactory getTextLayoutFactory()

selectAt

public Mark selectAt(double x,
                     double y,
                     TextNode node)
Given an X, y coordinate, AttributedCharacterIterator, return a Mark which encapsulates a "selection start" action. The standard order of method calls for selection is: selectAt(); [selectTo(),...], selectTo(); getSelection().

Specified by:
selectAt in interface TextPainter

selectTo

public Mark selectTo(double x,
                     double y,
                     Mark beginMark)
Given an X, y coordinate, starting Mark, AttributedCharacterIterator, return a Mark which encapsulates a "selection continued" action. The standard order of method calls for selection is: selectAt(); [selectTo(),...], selectTo(); getSelection().

Specified by:
selectTo in interface TextPainter

getGeometryBounds

public Rectangle2D getGeometryBounds(TextNode node)
Get a Rectangle2D in userspace coords which encloses the textnode glyphs just including the geometry info.

Specified by:
getGeometryBounds in interface TextPainter
Parameters:
node - the TextNode to measure

hitTest

protected abstract Mark hitTest(double x,
                                double y,
                                TextNode node)
Returns the mark for the specified parameters.
