- All Implemented Interfaces:
- TextPainter
- Direct Known Subclasses:
- ConcreteTextPainter, StrokingTextPainter
- public abstract class BasicTextPainter

selectAt
public Mark selectAt(double x,
double y,
java.text.AttributedCharacterIterator aci,
TextNode node,
GraphicsNodeRenderContext context)
- Given an X, y coordinate,
AttributedCharacterIterator, and GraphicsNodeRenderContext,
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
- Following copied from interface:
org.apache.batik.gvt.TextPainter
- Parameters:
x
- the x coordinate, in the text layout's coordinate system,
of the selection event.y
- the y coordinate, in the text layout's coordinate system,
of the selection event.aci
- the AttributedCharacterIterator describing the textcontext
- the GraphicsNodeRenderContext to use when doing text layout.- Returns:
- an instance of Mark which encapsulates the state necessary to
implement hit testing and text selection.
selectTo
public Mark selectTo(double x,
double y,
Mark beginMark,
java.text.AttributedCharacterIterator aci,
TextNode node,
GraphicsNodeRenderContext context)
- Given an X, y coordinate, starting Mark,
AttributedCharacterIterator, and GraphicsNodeRenderContext,
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
- Following copied from interface:
org.apache.batik.gvt.TextPainter

of the selection event.aci
- the AttributedCharacterIterator describing the textcontext
- the GraphicsNodeRenderContext to use when doing text layout.- Returns:
- an instance of Mark which encapsulates the state necessary to
implement hit testing and text selection.
selectAll
public Mark selectAll(double x,
double y,
java.text.AttributedCharacterIterator aci,
TextNode node,
GraphicsNodeRenderContext context)
- Select the entire contents of an
AttributedCharacterIterator, and
return a Mark which encapsulates that selection action.
- Specified by:

of the selection event.aci
- the AttributedCharacterIterator describing the textcontext
- the GraphicsNodeRenderContext to use when doing text layout.- Returns:
- an instance of Mark which encapsulates the state necessary to
implement hit testing and text selection.
getBounds
public java.awt.geom.Rectangle2D getBounds(TextNode node,
java.awt.font.FontRenderContext frc)
