Method Detail

activate

public void activate()

Specified by:

activate in interface IActivatable

Overrides:

activate in class AbstractBehavior<javafx.scene.Node>

applyStaticLayout

protected void applyStaticLayout()

Performs one layout pass using the static layout algorithm that is configured for the layout context.

deactivate

public void deactivate()

Specified by:

deactivate in interface IActivatable

Overrides:

deactivate in class AbstractBehavior<javafx.scene.Node>

getHost

public GraphContentPart getHost()

Specified by:

getHost in interface IBehavior<javafx.scene.Node>

Overrides:

getHost in class AbstractBehavior<javafx.scene.Node>

getLayoutModel

protected LayoutModel getLayoutModel()

getNestingPart

protected NodeContentPart getNestingPart()

getViewportModel

protected ViewportModel getViewportModel()

onHostPropertyChange

protected void onHostPropertyChange(java.beans.PropertyChangeEvent evt)

onLayoutContextPropertyChange

protected void onLayoutContextPropertyChange(java.beans.PropertyChangeEvent evt)

Re-layout when certain properties of the LayoutContext change:

• static layout algorithm
• layout bounds

Parameters:

evt - A PropertyChangeEvent that was fired by the layout context.

onNestingVisualLayoutBoundsChange

protected void onNestingVisualLayoutBoundsChange(javafx.geometry.Bounds oldLayoutBounds,
                                                 javafx.geometry.Bounds newLayoutBounds)

Sets the layout bounds on the layout context for nested graphs.

Parameters:

oldLayoutBounds - The previous nesting node's bounds.

newLayoutBounds - The current nesting node's bounds.

onViewportModelPropertyChange

protected void onViewportModelPropertyChange(java.beans.PropertyChangeEvent evt)
