Class SimpleLinePainter
java.lang.Object
oracle.javatools.editor.underline.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 of a given thickness.
Field Summary |
protected boolean |
fromBaseline
Whether the line is painted from the baseline (extending downwards for thickness) or from the descent below the baseline (extending upwards for thickness.) |
static int |
MAX_THICKNESS
The maximum thickness that can be specified to the line painter. |
protected int |
thickness
The thickness of the line to paint. |
Constructor Summary |
SimpleLinePainter(int thickness, boolean fromBaseline)
Constructs a new SimpleLinePainter of the specified thickness. |
Method Summary |
protected int |
getYPos(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 yBaseline, int descent)
Paints the underline using this implementation of the UnderlinePainter . |

MAX_THICKNESS
public static final int MAX_THICKNESS
- The maximum thickness that can be specified to the line painter.
- See Also:
- Constant Field Values
thickness
protected final int thickness
- The thickness of the line to paint.
fromBaseline
protected final boolean fromBaseline
- Whether the line is painted from the baseline (extending downwards for thickness) or from the descent below the baseline (extending upwards for thickness.)
SimpleLinePainter
public SimpleLinePainter(int thickness,
boolean fromBaseline)
- Constructs a new
SimpleLinePainter
of the specified thickness. Any thickness greater than MAX_THICKNESS will be automatically reduced. If fromBaseline is true, the line is painted from the baseline (downwards for thickness) or from the descent below the baseline (extending upwards for thickness.)
- Parameters:
thickness
- the thickness of the line to paint
fromBaseline
- true if the underline extends from the baseline
getYPos
protected int getYPos(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 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
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
