/**
 * @deprecated 5.0
 * Provides a convenient wrapper for TextFields that adds a clickable trigger button.
 * (looks like a combobox by default).
 *
 * As of Ext JS 5.0 this class has been deprecated.  It is recommended to use a
 * {@link Ext.form.field.Text Text Field} with the {@link Ext.form.field.Text#triggers
 * triggers} config instead.  This class is provided for compatibility reasons but is
 * not used internally by the framework.
