- * @class Ext.form.TriggerField
- * @extends Ext.form.TextField
- * Provides a convenient wrapper for TextFields that adds a clickable trigger button (looks like a combobox by default).
- * The trigger has no default action, so you must assign a function to implement the trigger click handler by
- * overriding {@link #onTriggerClick}. You can create a TriggerField directly, as it renders exactly like a combobox
- * for which you can provide a custom implementation. For example:
- * <pre><code>
-var trigger = new Ext.form.TriggerField();
-trigger.onTriggerClick = myTriggerFn;
-trigger.applyToMarkup('my-field');
-</code></pre>
- *
- * However, in general you will most likely want to use TriggerField as the base class for a reusable component.
- * {@link Ext.form.DateField} and {@link Ext.form.ComboBox} are perfect examples of this.
- *
- * @constructor
- * Create a new TriggerField.
- * @param {Object} config Configuration options (valid {@Ext.form.TextField} config options will also be applied
- * to the base TextField)
- * @xtype trigger
