getTextLayoutFactory

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 java.awt.geom.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.
