public class JCLineStyle
extends JCStyle
JCLineStyle controls how a line is drawn. It stores the line pattern and line width, and then draws lines accordingly.

Properties

Name Method
Pattern The Pattern property dictates the pattern used to draw a line. Valid values include JCLineStyle.NONE, JCLineStyle.SOLID, JCLineStyle.LONG_DASH, JCLineStyle.SHORT_DASH, JCLineStyle.LSL_DASH and JCLineStyle.DASH_DOT. Note: Since Java does not support line patterns, this property is currently not supported. The default value is JCLineStyle.SOLID.
Width The Width property controls the line width. Note: Since Java only supports width-1 lines, this property is currently not supported. The default value is 1.
Color The Color property determines the color used to draw a line. The default value is generated.

Constructor Index

o JCLineStyle(int, Color, int)
Constructor for line style objects.

Method Index

o draw(Graphics, int, int, int, int)
Draws a line between two points according to the properties of the JCLineStyle instance.
o getColor()
Gets the Color property of JCLineStyle, which determines the color used to draw the line.
o getPattern()
Gets the Pattern property, which dictates the pattern used to draw a line.
o getWidth()
Gets the Width property, which controls line width.
o makeDefault(JCChart)
Creates a default line style
o setColor(Color)
Sets the Color property of JCLineStyle, which determines the color used to draw the line.
o setPattern(int)
Sets the Pattern property, which dictates the pattern used to draw a line.
o setWidth(int)
Sets the Width property, which controls line width.

Constructors

o JCLineStyle 
 public JCLineStyle(int w,
                    Color c,
                    int p)
Constructor for line style objects.

Parameters:
w - line width
c - line color
p - line pattern. One of NONE, SOLID, LONG_DASH, LSL_DASH or DASH_DOT.

Methods

o makeDefault 
 public static JCLineStyle makeDefault(JCChart c)
Creates a default line style

Returns:
JCLineStyle object with default width, color and pattern. The defaults are cycled, so consecutive calls will return different line styles.
o draw 
 public void draw(Graphics gc,
                  int x1,
                  int y1,
                  int x2,
                  int y2)
Draws a line between two points according to the properties of the JCLineStyle instance.

Parameters:
gr - graphics context to use for drawing.
x1 - x value of first point (in pixels)
y1 - y value of first point (in pixels)
x2 - x value of second point (in pixels)
y2 - y value of second point (in pixels)
o getPattern 
 public int getPattern()
Gets the Pattern property, which dictates the pattern used to draw a line.

Returns:
one of NONE, SOLID, LONG_DASH, SHORT_DASH, LSL_DASH or DASH_DOT
o setPattern 
 public synchronized void setPattern(int p)
Sets the Pattern property, which dictates the pattern used to draw a line.

Parameters:
p - one of NONE, SOLID, LONG_DASH, SHORT_DASH, LSL_DASH or DASH_DOT
Throws: IllegalArgumentException
If the patter is not one of NONE, SOLID, LONG_DASH, SHORT_DASH, LSL_DASH or DASH_DOT.
o getWidth 
 public int getWidth()
Gets the Width property, which controls line width.

Returns:
positive integer representing line width
o setWidth 
 public synchronized void setWidth(int w)
Sets the Width property, which controls line width.

Parameters:
w - positive integer representing line width
o getColor 
 public Color getColor()
Gets the Color property of JCLineStyle, which determines the color used to draw the line.

Returns:
AWT Color class representing the color to be used to draw the lines. If null, the current color of the Graphics object is used.
o setColor 
 public synchronized void setColor(Color clr)
Sets the Color property of JCLineStyle, which determines the color used to draw the line.

Parameters:
clr - AWT Color class representing the color to be used to draw the lines. If null, the current color of the Graphics object is used.
