All Implemented Interfaces:

public class LinkPart
extends org.eclipse.gef.editparts.AbstractConnectionEditPart
implements PropertyChangeListener

proves the GEF editPart that manages the display of the connection lines between reference objects in the reference/annotation display. Model data for these is the Link object.

As well as tracking any change in the connections in the model, this code also tracks its Link's LOType for changes in associated Type, and changes in the current type's colour parameters.

Constructor Detail

LinkPart

public LinkPart(IHasConnectionLayer myRootPart,
                Link link)
Method Detail

getLink

public Link getLink()

createFigure

protected org.eclipse.draw2d.IFigure createFigure()

createEditPolicies

protected void createEditPolicies()

getTheConnectionLayer

protected org.eclipse.draw2d.ConnectionLayer getTheConnectionLayer()

activateFigure

protected void activateFigure()
Activates the Figure representing this connection object. This overrides the normal process to achieve the layering of the connections in the contained object, rather than at the very top.

See Also:
deactivate()

deactivateFigure

protected void deactivateFigure()
Deactivates the Figure representing this, by removing it from the connection layer, and resetting the source and target connections to null.


activate

public void activate()
Upon activation, attach to the model element as a property change listener.

Specified by:
activate in interface org.eclipse.gef.EditPart

deactivate

public void deactivate()
Upon deactivation, detach from the model element as a property change listener.

Specified by:
deactivate in interface org.eclipse.gef.EditPart

propertyChange

public void propertyChange(PropertyChangeEvent arg0)
Specified by:
propertyChange in interface PropertyChangeListener
