Eclipse Draw2d
3.3

org.eclipse.draw2d
Class Polyline

java.lang.Object
  extended by

org.eclipse.draw2d.Figure
      extended by

org.eclipse.draw2d.Shape
          extended by

org.eclipse.draw2d.AbstractPointListShape
              extended by
org.eclipse.draw2d.Polyline
All Implemented Interfaces:
IFigure
Direct Known Subclasses:
Polygon, PolylineConnection, PolylineDecoration

public class Polyline
extends AbstractPointListShape

Renders a PointList as a series of line segments. A Polyline figure should be positioned by manipulating its points, NOT by calling Figure.setBounds(Rectangle).

A polyline's bounds will be calculated automatically based on its PointList. The bounds will be the smallest Rectangle large enough to render the line properly. Children should not be added to a Polyline and will not affect the bounds calculation.

Constructor Detail

Polyline

public Polyline()
Method Detail

containsPoint

public boolean containsPoint(int x,
                             int y)
Description copied from interface: IFigure
Returns true if the point (x, y) is contained within this IFigure's bounds.

Specified by:
containsPoint in interface IFigure
Overrides:
containsPoint in class AbstractPointListShape
See Also:
IFigure.containsPoint(int, int)

shapeContainsPoint

protected boolean shapeContainsPoint(int x,
                                     int y)
Description copied from class: AbstractPointListShape
Returns true if the point (x, y) is contained within this figure.

Specified by:
shapeContainsPoint in class AbstractPointListShape
Parameters:
x - The X coordinate
y - The Y coordinate
Returns:
true if the point (x,y) is contained in this figure

fillShape

protected void fillShape(
Graphics g)
Null implementation for a line.

Specified by:
fillShape in class Shape
Parameters:
g - the graphics object
See Also:
Shape.fillShape(Graphics)

getBounds

public 
Rectangle getBounds()
Description copied from class: Figure
Returns the smallest rectangle completely enclosing the figure. Implementors may return the Rectangle by reference. For this reason, callers of this method must not modify the returned Rectangle.

Specified by:
getBounds in interface IFigure
Overrides:
getBounds in class Figure
Returns:
The bounds of this Figure
See Also:
IFigure.getBounds()

isOpaque

public boolean isOpaque()
Description copied from interface: IFigure
Returns true if this IFigure is opaque.

Specified by:
isOpaque in interface IFigure
Overrides:
isOpaque in class Figure
Returns:
false because Polyline's aren't filled
See Also:
IFigure.isOpaque()

outlineShape

protected void outlineShape(
Graphics g)
Description copied from class: Shape
Outlines this shape using the foreground color.

Specified by:
outlineShape in class Shape
Parameters:
g - the graphics object
See Also:
Shape.outlineShape(Graphics)

primTranslate

public void primTranslate(int x,
                          int y)
Description copied from class: Figure
Translates this Figure's bounds, without firing a move.

Overrides:
primTranslate in class Figure
Parameters:
x - The amount to translate horizontally
y - The amount to translate vertically
See Also:
Figure.primTranslate(int, int)

removeAllPoints

public void removeAllPoints()

Shape.setLineWidth(int)

setPoints

public void setPoints(

Sets the list of points to be used by this polyline connection. Removes any previously existing points. The polyline will hold onto the given list by reference.

Overrides:
setPoints in class AbstractPointListShape
Parameters:
points - new set of points

2.0

setTolerance

public void setTolerance(int tolerance)
