Class GFEllipseDecoration

  • All Implemented Interfaces:
    org.eclipse.draw2d.IFigure, org.eclipse.draw2d.RotatableDecoration, org.eclipse.gef.handles.HandleBounds, IVisualStateChangeListener, IVisualStateHolder

    public class GFEllipseDecoration
    extends GFAbstractRotatableDecoration
    implements org.eclipse.draw2d.RotatableDecoration
    A Graphiti Ellipse Rotatable Decoration. Most functionality is handled in the super-class. This class only has to define the path and the touch-point for the figure-specific painting.

                                   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.

      • 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.
