Each qooxdoo object has a hash code. You can retrieve it like so:
var txtName = new qx.ui.form.TextField();
var txtNameHash = txtName.toHashCode();
The hash codes and widgets are stored in a registry, so you can retrieve the
widget later with:
txtName = qx.core.ObjectRegistry.fromHashCode(txtHashName);
Now the question is, why do you need to do that? If you're going to be
storing the hash code (e.g., txtNameHash) someplace, why can't you instead
store the widget reference itself (e.g., txtName) there, and avoid the
dereference to retrieve the widget reference?
