/**
 * @class Ext.calendar.EventEditForm
 * @extends Ext.form.FormPanel
 * <p>A custom form used for detailed editing of events.</p>
 * <p>This is pretty much a standard form that is simply pre-configured for the options needed by the
 * calendar components. It is also configured to automatically bind records of type {@link Ext.calendar.EventRecord}
 * to and from the form.</p>
 * <p>This form also provides custom events specific to the calendar so that other calendar components can be easily
 * notified when an event has been edited via this component.</p>
 * <p>The default configs are as follows:</p><pre><code>
    labelWidth: 65,
    title: 'Event Form',
    titleTextAdd: 'Add Event',
    titleTextEdit: 'Edit Event',
    bodyStyle: 'background:transparent;padding:20px 20px 10px;',
    border: false,
    buttonAlign: 'center',
    autoHeight: true,
    cls: 'ext-evt-edit-form',
</code></pre>
 * @constructor
 * @param {Object} config The config object
