this.getBubbleTarget() if present... Enables events fired by this Observable to bubble up an owner hierarchy by calling
this.getBubbleTarget() if present. There is no implementation in the Observable base class.
This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component.getBubbleTarget. The default
implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to
access the required target more quickly.
Example: Ext.override(Ext.form.Field, {
-// Add functionality to Field's initComponent to enable the change event to bubble
- initComponent: Ext.form.Field.prototype.initComponent.createSequence(function() {
- this.enableBubble('change');
