VR
- The visual root node of the UI toolkit, e.g. javafx.scene.Node in
case of JavaFX.public class DetachFromContentAnchorageOperation<VR> extends AbstractOperation implements ITransactionalOperation
DetachFromContentAnchorageOperation
uses the IContentPart
API to detach an anchored from the given anchorage.Constructor and Description |
---|
DetachFromContentAnchorageOperation(IContentPart<VR,? extends VR> anchored,
java.lang.Object contentAnchorage,
java.lang.String role)
Creates a new
DetachFromContentAnchorageOperation to detach the
given anchored IContentPart from the given
contentAnchorage under the specified role, so that it will
not be returned by subsequent calls to
IContentPart.getContentAnchoragesUnmodifiable() . |
