* XObject
* Yet another attempt to create a usable object construction library for seed..
* Xyz.init(); // create and show.
*
*
- * use XObject.debug = 1 to turn on debugging
*
- * If XObjectBase/[xns]/[xtype].js exists, it will use this to override properties..
+ * @arg xtype {String|Function} constructor or string.
+ * @arg id {String} (optional) id for registry
+ * @arg xns {String|Object} (optional) namespace eg. Gtk or 'Gtk' - used with xtype.
+ * @arg items {Array} (optional) list of child elements which will be constructed.. using XObject
+ * @arg listeners {Object} (optional) map Gobject signals to functions
+ * @arg pack {Function|String|Array} (optional) how this object gets added to it's parent
+ * @arg el {Object} (optional) premade GObject
+ *
+ * --- needs a xdebug option!
*
*
* He's some questions.
+ * - should we generate ID's for all elements? (if so we probably need to garbage collect)
* - should we have a special property to use as the constructor / gobject.properties rather
* than sending all basic types to this?
*
- * @cfg xtype {String|Function} constructor or string.
- * @cfg id {String} (optional) id for registry
- * @cfg xns {String|Object} (optional) namespace eg. Gtk or 'Gtk' - used with xtype.
- * @cfg items {Array} (optional) list of child elements which will be constructed.. using XObject
- * @cfg listeners {Object} (optional) map Gobject signals to functions
- * @cfg pack {Function|String|Array} (optional) how this object gets added to it's parent
- * @cfg el {Object} (optional) premade GObject
