getTargetPart

public static <T extends IPolicy<javafx.scene.Node>> IVisualPart<javafx.scene.Node,? extends javafx.scene.Node> getTargetPart(java.util.Collection<IViewer<javafx.scene.Node>> viewers,
                                                                                                                              javafx.scene.Node visual,
                                                                                                                              java.lang.Class<T> supportedPolicy,
                                                                                                                              boolean searchHierarchy)

Returns the first IVisualPart in the given list of viewers, for which both of the following properties hold:

1. Supports the specified policy (which may be null).
2. Provides a visual that belongs to the parent hierarchy of the given visual.

When no policy is specified (i.e. it is null), the first visual part that controls a visual in the hierarchy is returned. When the searchHierarchy is set to false only the first visual part is considered.

Parameters:

viewers - Collection of all IViewers.

visual - Node visual that received an event.

supportedPolicy - Class of the IPolicy which has to be supported by the target part. May be null to indicate that the target part does not have to support a specific policy.

searchHierarchy - If set to true, the full visual part hierarchy will be searched, otherwise, the direct target part alone is considered.

Returns:

The first suitable target part, or null if no suitable target part can be found.
