The defaultValue of the property wrap is true (-> defined in
qx.ui.basic.Label). So for every property which is declared in the original
appearance (->"label") and NOT declared in the new appearance (->"link-ref")
the setAppearance-method will reset the property to its defaultValue. That's
why the property wrap is set to true, rather than using the value of the
appearance "label" or using the user value.
The reason for this behaviour is, that qooxdoo (in the 0.6.x codebase) is not
aware of multi-values for properties (qooxdoo 0.7 will support multi-values
for properties. So there will be no overwriting of user-values with
appearance values).
To start from zero it uses the defaultValue for all properties which are
defined in the original appearance, but not in the new one.

The appearance system looks for the original appearance for this widget. By
default the appearance for any label widget is "label". So this original
appearance is overwritten with the values from the new appearance. And again,
all properties which are declared in the original one and NOT in the new one
are falling back to default. To start from zero ;-)

You overwrite the old property with the property value of the new appearance
(if defined). The appearance are not merged, it's a selective overwriting of
property values defined in both appearances and a resetting of all properties
from the original appearance which have no counterpart in the new one.
I hope, now the appearance system has become a little bit clearer or did I
confuse you even more? ;-)
cheers,
Alex
