@xtype

Synopsis:

@xtype name

Documents xtype of the class.

Example:

/**
 * @class Ext.grid.Panel
 * The grid of data.
 * @xtype grid
 */

Writing @xtype grid is shorthand for @alias widget.grid. See @alias for details.

Auto-detection

This tag is auto-detected when class comment is right above Ext.define which contains xtype:. The following code is equivalent of the above one:

/**
 * The grid of data.
 */
Ext.define("Ext.grid.Panel", {
    xtype: "grid",
});

Otherwise the auto-detection behaves just like with @alternateClassName tag.
