wxVariant list used to translate between list of property child values and composite value string now maps values by names instead of labels. Naturally this means properties can no longer have empty name (this change allows using identical labels under same parent property. Ported from wxpropgrid SVN trunk)

Naturally, wxStringProperty is a property class. Only the first function argument (label)
is mandatory. Second one, name, defaults to label and, third, the initial value, to
default value. If constant wxPG_LABEL is used as the name argument, then the label is
automatically used as a name as well (this is more efficient than manually
defining both as the same). Empty name is also allowed, but in this case the
property cannot be accessed by its name. Note that all property class constructors have
quite similar constructor argument list.
automatically used as a name as well (this is more efficient than manually defining both
as the same). Use of empty name is discouraged and will sometimes result in run-time error.
Note that all property class constructors have quite similar constructor argument list.
To demonstrate other common property classes, here's another code snippet:
