/** * @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: *

var trigger = new Ext.form.TriggerField();
trigger.onTriggerClick = myTriggerFn;
trigger.applyToMarkup('my-field');
* * 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 */ Ext.form.TriggerField = Ext.extend(Ext.form.TextField, {
