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