/**
|
* @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
|
