All Implemented Interfaces:

com.globalmentor.beans.GenericPropertyChangeListener<java.lang.Object>, java.beans.PropertyChangeListener, java.util.EventListener

Enclosing class:

AbstractLayout<T extends Constraints>

protected class AbstractLayout.ConstraintsPropertyChangeListener
extends com.globalmentor.beans.AbstractGenericPropertyChangeListener<java.lang.Object>

A property change listener that listens for changes in a constraint object's properties and fires a layout constraints property change event in response. A LayoutConstraintsPropertyChangeEvent will be fired for each component associated with the constraints for which a property changed. Events are only fired for constraints of a type recognized by this layout.

Method Detail

propertyChange

public void propertyChange(com.globalmentor.beans.GenericPropertyChangeEvent<java.lang.Object> propertyChangeEvent)

Called when a bound property is changed. This implementation fires a LayoutConstraintsPropertyChangeEvent indicating the constraints and associated component.

Parameters:

propertyChangeEvent - An event object describing the event source, the property that has changed, and its old and new values.

refirePropertyChange

protected <V> void refirePropertyChange(Component component,
                                        T constraints,
                                        java.lang.String propertyName,
                                        V oldValue,
                                        V newValue)

Refires a constraint property change event for the layout in the form of a LayoutConstraintsPropertyChangeEvent.

Parameters:

component - The component for which a constraint value changed.

constraints - The constraints for which a value changed.

propertyName - The name of the property being changed.

oldValue - The old property value.

newValue - The new property value.
