Here is something I don't understand:
qx.Class.include(qx.ui.form.List,qx.io.databinding.MDataManager);
for (var i in qx.ui.form.List)
qx.core.Log.error(i + ": " + qx.ui.form.List[i]);
I get the following list:
$$original: function () { <snip/>}
classname: qx.ui.form.List
name: anonymous
basename: List
toString: function () { return "[Class " + this.classname + "]"; }
prototype: [object qx.ui.form.List]
superclass: [Class qx.ui.layout.VerticalBoxLayout]
constructor: [Class qx.ui.form.List]
$$destructor: function () { this._disposeObjects("_manager"); }
$$properties: [object Object]
$$includes: [Mixin qx.io.databinding.MDataManager]
$$flatIncludes: [Mixin qx.io.databinding.MDataManager]
I am always amazed and surprised once I dive into the internals of
qooxdoo... where are all the getter and setter methods here? why don't
they show up if I do a "for (.. in..)" loop?
