+<code>this.getBubbleTarget()</code> if present. There is no implementation in the Observable base class.</p>
+<p>This is commonly used by Ext.Components to bubble events to owner Containers. See <a href="output/Ext.Component.getBubbleTarget.html" ext:cls="Ext.Component.getBubbleTarget">Ext.Component.getBubbleTarget</a>. 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.</p>
+<p>Example:</p><pre><code>Ext.override(Ext.form.Field, {
+ <i>// Add functionality to Field's initComponent to enable the change event to bubble</i>
+ initComponent : Ext.form.Field.prototype.initComponent.createSequence(<b>function</b>() {
+ this.enableBubble(<em>'change'</em>);
+ }),
+
+ <i>// We know that we want Field's events to bubble directly to the FormPanel.</i>
+ getBubbleTarget : <b>function</b>() {
+ <b>if</b> (!this.formPanel) {
+ this.formPanel = this.findParentByType(<em>'form'</em>);
+ }
+ <b>return</b> this.formPanel;
