9  * @class Roo.bootstrap.TriggerField
10  * @extends Roo.bootstrap.Input
11  * Provides a convenient wrapper for TextFields that adds a clickable trigger button (looks like a combobox by default).
12  * The trigger has no default action, so you must assign a function to implement the trigger click handler by
13  * overriding {@link #onTriggerClick}. You can create a TriggerField directly, as it renders exactly like a combobox
14  * for which you can provide a custom implementation.  For example:
15  * <pre><code>
16 var trigger = new Roo.bootstrap.TriggerField();
17 trigger.onTriggerClick = myTriggerFn;
18 trigger.applyTo('my-field');
19 </code></pre>
20  *
21  * However, in general you will most likely want to use TriggerField as the base class for a reusable component.
22  * {@link Roo.bootstrap.DateField} and {@link Roo.bootstrap.ComboBox} are perfect examples of this.
23  * @cfg {String} triggerClass An additional CSS class used to style the trigger button.  The trigger will always get the
24  * class 'x-form-trigger' by default and triggerClass will be <b>appended</b> if specified.
25  * @cfg {String} caret (search|calendar) a fontawesome for the trigger icon see http://fortawesome.github.io/Font-Awesome/icons/
26
27  * @constructor
28  * Create a new TriggerField.
29  * @param {Object} config Configuration options (valid {@Roo.bootstrap.Input} config options will also be applied
30  * to the base TextField)
