Constructor and Description 

GlyphView.GlyphPainter() 
Modifier and Type  Method and Description 

abstract float 
getAscent(GlyphView v) 
abstract int 
getBoundedPosition(GlyphView v,
int p0,
float x,
float len)
Determines the model location that represents the
maximum advance that fits within the given span.

abstract float 
getDescent(GlyphView v) 
abstract float 
getHeight(GlyphView v) 
int 
getNextVisualPositionFrom(GlyphView v,
int pos,
Position.Bias b,
Shape a,
int direction,
Position.Bias[] biasRet)
Provides a way to determine the next visually represented model
location that one might place a caret.

GlyphView.GlyphPainter 
getPainter(GlyphView v,
int p0,
int p1)
Create a painter to use for the given GlyphView.

abstract float 
getSpan(GlyphView v,
int p0,
int p1,
TabExpander e,
float x)
Determine the span the glyphs given a start location
(for tab expansion).

abstract Shape 
modelToView(GlyphView v,
int pos,
Position.Bias bias,
Shape a)
Provides a mapping from the document model coordinate space
to the coordinate space of the view mapped to it.

abstract void 
paint(GlyphView v,
Graphics g,
Shape a,
int p0,
int p1)
Paint the glyphs representing the given range.

abstract int 
viewToModel(GlyphView v,
float x,
float y,
Shape a,
Position.Bias[] biasReturn)
Provides a mapping from the view coordinate space to the logical
coordinate space of the model.
