Class SimpleLinePainter

java.lang.Object
oracle.javatools.editor.highlight.SimpleLinePainter

All Implemented Interfaces:

UnderlinePainter

Direct Known Subclasses:

DottedLinePainter, ZigZagLinePainter

public class SimpleLinePainter

extends java.lang.Object

implements UnderlinePainter

The SimpleLinePainter is an implementation of the UnderlinePainter which paints a straight underline or separator of a given thickness.

Field Summary

protected int	_thickness The thickness of the line to paint.
protected int	_underlineType The type of underline, such as TYPE_UNDERLINE or TYPE_SEPARATOR.
static int	MAX_THICKNESS The maximum thickness that can be specified to the line painter.

Fields inherited from interface oracle.javatools.editor.highlight.UnderlinePainter

TYPE_SEPARATOR, TYPE_STRIKETHRU, TYPE_UNDERLINE

Constructor Summary

SimpleLinePainter(int thickness, int underlineType)
Constructs a new SimpleLinePainter of the specified thickness.

Method Summary

int	getUnderlineType() Fetch the type of underline, such as TYPE_SEPARATOR.
protected int	getYPos(int yTop, int yBaseline, int descent) Utility routine to calculate the appropriate y position to start painting downwards from, based on the requested paint position (from baseline or from bottom), and the yBaseline coordinate and the descent.)
void	paintUnderline(java.awt.Graphics graphics, java.awt.Color color, int xPos, int width, int yTop, int yBaseline, int descent) Paints the underline using this implementation of the UnderlinePainter.

Constant Field Values

_thickness

protected final int _thickness

The thickness of the line to paint.

_underlineType

protected final int _underlineType

The type of underline, such as TYPE_UNDERLINE or TYPE_SEPARATOR.

Constructor Detail

SimpleLinePainter

public SimpleLinePainter(int thickness,
                         int underlineType)

Constructs a new SimpleLinePainter of the specified thickness. Any thickness greater than MAX_THICKNESS will be automatically reduced. The type of underline indicates where the underline will be painted.

Parameters:

thickness - the thickness of the line to paint

underlineType - the type of underline, such as TYPE_SEPARATOR

Method Detail

getYPos

protected int getYPos(int yTop,
                      int yBaseline,
                      int descent)

Utility routine to calculate the appropriate y position to start painting downwards from, based on the requested paint position (from baseline or from bottom), and the yBaseline coordinate and the descent.)

Parameters:

yBaseline - the y position of the baseline

descent - the descent of the text below the baseline

paintUnderline

public void paintUnderline(java.awt.Graphics graphics,
                           java.awt.Color color,
                           int xPos,
                           int width,
                           int yTop,
                           int yBaseline,
                           int descent)

Paints the underline using this implementation of the UnderlinePainter.

Specified by:

paintUnderline in interface UnderlinePainter

Parameters:

graphics - the graphics context to paint into

color - the color to use for painting the underline

xPos - the x position to start painting from

width - the width of the underline to paint

yTop - the y position of the top of the text

yBaseline - the y position of the baseline of the text we are drawing an underline for

descent - the descent of the font the text was drawn with

getUnderlineType

public int getUnderlineType()

Fetch the type of underline, such as TYPE_SEPARATOR.

Specified by:

getUnderlineType in interface UnderlinePainter

Returns:

the underline type
