Class AbstractHidingBehavior

java.lang.Object

org.eclipse.gef4.mvc.behaviors.AbstractBehavior<javafx.scene.Node>

org.eclipse.gef4.zest.fx.behaviors.AbstractHidingBehavior

All Implemented Interfaces:

IActivatable, IAdaptable.Bound<IVisualPart<javafx.scene.Node,? extends javafx.scene.Node>>, IPropertyChangeNotifier, IBehavior<javafx.scene.Node>

Direct Known Subclasses:

EdgeHidingBehavior, EdgeLabelHidingBehavior

public abstract class AbstractHidingBehavior
extends AbstractBehavior<javafx.scene.Node>

The AbstractHidingBehavior registers listeners on the HidingModel upon activation. When the HidingModel changes, the hidden status of the host is determined. If the hidden status of the host changed, either hide() or show() will be called, respectively. By default, the host's visual's visibility and mouse-transparency are changed depending on the hidden status.

determineHiddenStatus

protected abstract boolean determineHiddenStatus()

Returns true if the host is currently hidden. Otherwise, returns false.

Returns:

true if the host is currently hidden, otherwise false.

getHidingModel

protected HidingModel getHidingModel()

Returns the HidingModel that is installed on the IViewer of the host.

Returns:

The HidingModel that is installed on the IViewer of the host.

hide

protected void hide()

Hides the host. By default, the host's visual's visibility will be set to false and its mouse-transparency will be set to true.

isHidden

protected boolean isHidden()

Returns true if the host is currently considered to be hidden. Otherwise, returns false.

Returns:

true if the host is currently considered to be hidden, otherwise false.

onHidingModelChange
