public class GFEllipseDecoration

Constructor Details

GFEllipseDecoration

public GFEllipseDecoration(IPictogramElementDelegate pictogramElementDelegate,
 GraphicsAlgorithm graphicsAlgorithm)

Creates a new GFEllipseDecoration.

Parameters:

pictogramElementDelegate - The PictogramElementDelegate which provides the GraphicsAlgorithm.

graphicsAlgorithm - The GraphicsAlgorithm which provides the values to paint this Shape.

Method Details

getInitialTouchPoint

protected org.eclipse.draw2d.geometry.Point getInitialTouchPoint()

Returns the initial touch-point of the decorator-shape. This is the point of the decorator-shape inside the initial-bounds (see GFAbstractRotatableDecoration.getInitialBounds()), which shall touch the decorated figure at the decorator-location (see GFAbstractRotatableDecoration.getDecoratorLocation(). It is called "inital" because it is the point before translation/rotation.

In caes of this Ellipse the point (0, getInitialBounds().height / 2) is returned.

Specified by:

getInitialTouchPoint in class GFAbstractRotatableDecoration

Returns:

The initial touch-point of the decorator-shape.

containsPointInInitialFigure

public boolean containsPointInInitialFigure(int x,
 int y)

Returns true, if the given point is contained inside this ellipse. This implementation overwrites the super-implementation, which only checks if the point is in the rectangular bounds.

Overrides:

containsPointInInitialFigure in class GFAbstractRotatableDecoration

Parameters:

x - The x-coordinate of the point to check.

y - The y-coordinate of the point to check.

Returns:

true, if the given point is contained inside this ellipse.

createPath

protected org.eclipse.swt.graphics.Path createPath(org.eclipse.draw2d.geometry.Rectangle outerBounds,
 org.eclipse.draw2d.Graphics graphics,
 boolean isFill)

Returns the Path specifying an ellipse for the given outer bounds. It does not differentiate between a fill Path and an outline Path.

Specified by:

createPath in class GFAbstractShape

Parameters:

outerBounds - The outer bounds which shall contain the Path. They are calculated from the bounds of this figure by GFFigureUtil.getAdjustedRectangle(Rectangle, double, int) . Note, that those outline-bounds are just a suggestion which works fine for many cases.

graphics - The Graphics on which the outline Path shall be painted. It can be used to react on Graphics specific values, like the zoom-level of the Graphics.

isFill - if true, the Path is used for filling the Shape, otherwise for outlining the Shape.

Returns:

The Path specifying an ellipse for the given outer bounds.
