Method Detail

activate

public void activate()

Specified by:

activate in interface CanvasView

Overrides:

activate in class SwingView

clean

public void clean()

Description copied from interface: CanvasView

Cleans up this view. This method should be called when a view is deactivated. The view can be reused later, by invalidating it.

Specified by:

clean in interface CanvasView

Overrides:

clean in class SwingView

getLayoutEngine

public GraphLayoutEngine getLayoutEngine()

getNewInstance

public CanvasView getNewInstance(GraphCanvas canvas)

Specified by:

getNewInstance in interface CanvasView

Overrides:

getNewInstance in class AbstractView

invalidate

public void invalidate()

Description copied from interface: CanvasView

Forces the view to reevaluate its internal state. This method is called whenever the structure of the graph changes

Specified by:

invalidate in interface CanvasView

Overrides:

invalidate in class AbstractView

invalidate

public void invalidate(boolean ignoreOld)

isEditable

public boolean isEditable()

reLayout

public void reLayout()

Specified by:

reLayout in interface CanvasView

Overrides:

reLayout in class AbstractView

setLayoutEngine

public void setLayoutEngine(GraphLayoutEngine layoutEngine)

setCenter

public void setCenter(Component component,
                      Point p)

getCenter

public Point getCenter(Component component)

setEdgeCoords
