getHost

public AbstractFXSegmentHandlePart<javafx.scene.Node> getHost()

Description copied from interface: IPolicy

Returns the host of this IPolicy, i.e. the IVisualPart this IPolicy is attached to.

Specified by:

getHost in interface IPolicy<javafx.scene.Node>

Overrides:

getHost in class AbstractPolicy<javafx.scene.Node>

Returns:

The host of this IPolicy.

getScaleRelocatePolicy

protected FXScaleRelocatePolicy getScaleRelocatePolicy(IContentPart<javafx.scene.Node,? extends javafx.scene.Node> part)
