4 * trigger field - base class for combo..
9 * @class Roo.bootstrap.form.TriggerField
10 * @extends Roo.bootstrap.form.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:
16 var trigger = new Roo.bootstrap.form.TriggerField();
17 trigger.onTriggerClick = myTriggerFn;
18 trigger.applyTo('my-field');
21 * However, in general you will most likely want to use TriggerField as the base class for a reusable component.
22 * {@link Roo.bootstrap.form.DateField} and {@link Roo.bootstrap.form.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) BS3 only - carat fa name
28 * Create a new TriggerField.
29 * @param {Object} config Configuration options (valid {@Roo.bootstrap.form.Input} config options will also be applied
30 * to the base TextField)
32 Roo.bootstrap.form.TriggerField = function(config){
33 this.mimicing = false;
34 Roo.bootstrap.form.TriggerField.superclass.constructor.call(this, config);
37 Roo.extend(Roo.bootstrap.form.TriggerField, Roo.bootstrap.form.Input, {
39 * @cfg {String} triggerClass A CSS class to apply to the trigger
42 * @cfg {Boolean} hideTrigger True to hide the trigger element and display only the base text field (defaults to false)
47 * @cfg {Boolean} removable (true|false) special filter default false
