Specified by:

addAttributeComponent in interface GraphElementComponentInterface

Parameters:

attr - the attribute that is registered as being able to be displayed.

ac - the component that will be used to display the attribute.

addDependentComponent

public void addDependentComponent(GraphElementComponent comp)

Adds a GraphElementComponent to the list of dependent GraphElementComponents. These will nearly always be EdgeComponents that are dependent on their source or target nodes.

Specified by:

addDependentComponent in interface GraphElementComponentInterface

Parameters:

comp - the GraphElementComponent that is added to the list of dependent components.

getDependentGraphElementComponents

public List<GraphElementComponent> getDependentGraphElementComponents()

attributeChanged

public void attributeChanged(Attribute attr)
                      throws ShapeNotFoundException

Called when an attribute of the GraphElement represented by this component has changed.

Specified by:

attributeChanged in interface GraffitiViewComponent

Specified by:

attributeChanged in interface GraphElementComponentInterface

Parameters:

attr - the attribute that has triggered the event.

Throws:

ShapeNotFoundException - DOCUMENT ME!

clearDependentComponentList

public void clearDependentComponentList()

Removes a GraphElementComponent from the list of dependent GraphElementComponents.

Specified by:

Overrides the original method to deal with zoomable containers It will not call the original repaint, which will call the repaintmanager with unzoomed coordinates and local coordinates relativ to this graphcomponent so x and y are always 0 to create the correct repaint region we call the parent frame with new coordinates, which regard the zoom the parent will then call its repaintmanager, which will have then the correct coordinates to paint. This component will then be repainted, because it falls in the clipping bounds with regard to the current zoom

Overrides:
