Class GFPolygon

  • All Implemented Interfaces:
    org.eclipse.draw2d.IFigure, org.eclipse.gef.handles.HandleBounds, IVisualStateChangeListener, IVisualStateHolder
    Direct Known Subclasses:
    GFPolygonDecoration

    public class GFPolygon
    extends GFPolyline
    A Graphiti Polygon Figure. Most functionality is handled in the super-class. This class only has to define the outline-path and fill-path for the figure-specific painting.

      • GFPolygon

        public GFPolygon​(IPictogramElementDelegate pictogramElementDelegate,
                         GraphicsAlgorithm graphicsAlgorithm)
        Creates a new GFPolygon.
        Parameters:
        pictogramElementDelegate - The PictogramElementDelegate which provides the GraphicsAlgorithm.
        graphicsAlgorithm - The GraphicsAlgorithm which provides the values to paint this Shape.

      • containsPointInFigure

        public boolean containsPointInFigure​(int x,
                                             int y)
        Returns true, if the given point is contained in this Polygon. This is the case if
        • The point is located in the Polygon
        • The point is contained in a child of this Shape
        Overrides:
        containsPointInFigure in class GFPolyline
        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 in this Polygon.

      • createPath

        protected org.eclipse.swt.graphics.Path createPath​(org.eclipse.draw2d.geometry.Rectangle outerBoundss,
                                                           org.eclipse.draw2d.Graphics graphics,
                                                           boolean isFill)
        Returns the Path specifying a polygon for the adjusted point-list (see GFPolyline.getAdjustedPointList(PointList, double, double)) of this Shape. Note, that the outer bounds are ignored to calculate the Path, in contrast to most other Shapes. It does not differenciate between a fill Path and an outline Path.
        Overrides:
        createPath in class GFPolyline
        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 a polygon for the point-list of this Shape.
