All Implemented Interfaces:

org.eclipse.draw2d.IFigure, org.eclipse.draw2d.RotatableDecoration, org.eclipse.gef.handles.HandleBounds, IVisualStateChangeListener, IVisualStateHolder

Direct Known Subclasses:

GFEllipseDecoration

public abstract class GFAbstractRotatableDecoration
extends GFAbstractShape
implements org.eclipse.draw2d.RotatableDecoration

This class is an abstract super-class for all RotatableDecorations in Graphiti. The main idea is, that the outline and fill-area of a RotatableDecoration is defined by a Path. Sub-classes usually only have to implement the abstract methods GFAbstractShape.createPath(Rectangle, Graphics, boolean) and getInitialTouchPoint().

Constructor Detail

GFAbstractRotatableDecoration

public GFAbstractRotatableDecoration(IPictogramElementDelegate pictogramElementDelegate,
                                     GraphicsAlgorithm graphicsAlgorithm)

Creates a new GFAbstractRotatableDecoration.

Parameters:

pictogramElementDelegate - The PictogramElementDelegate which provides the GraphicsAlgorithm.

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

Method Detail

setLocation

public void setLocation(org.eclipse.draw2d.geometry.Point p)

Sets the decorator-location.

Specified by:

setLocation in interface org.eclipse.draw2d.IFigure

Specified by:

setLocation in interface org.eclipse.draw2d.RotatableDecoration

Overrides:

setLocation in class org.eclipse.draw2d.Figure

Parameters:

p - The decorator-location to set.

See Also:

getDecoratorLocation()

setReferencePoint

public void setReferencePoint(org.eclipse.draw2d.geometry.Point ref)

Sets the decorator-reference-point. Calls processRotatableDecorationValues() afterwards to initialize the rotated rectangle values.

Specified by:

setReferencePoint in interface org.eclipse.draw2d.RotatableDecoration

Parameters:

ref - The decorator-reference-point to set.

See Also:

getDecoratorReferencePoint()

getBounds

public org.eclipse.draw2d.geometry.Rectangle getBounds()

Returns the bounds of this decorator shape. This implementation bases on a rough calculation, which returns a bigger rectangle than necessary.

Specified by:

getBounds in interface org.eclipse.draw2d.IFigure

Overrides:

getBounds in class org.eclipse.draw2d.Figure

Returns:

The bounds of this decorator shape.

containsPointInFigure

public boolean containsPointInFigure(int x,
                                     int y)

Returns true, if the point is inside the translated/rotated rectangle. Specifics of the decorator Shape are ignored, but can be added by overwriting containsPointInInitialFigure(int, int).

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 Shape.

See Also:

GFAbstractShape.containsPoint(int, int)

containsPointInInitialFigure

public boolean containsPointInInitialFigure(int x,
                                            int y)

Returns true, if the point is inside the initial figure, meaning the figure in the getInitialBounds() before translation/rotation.

This implementation just returns true, but sub-classes can overwrite it to make decorator-shape specific checks.
