If you mean that the property doesn't show up in the .glade file: it
does. If you fire up glade3, add the custom widget to it and save the
file the custom property is there, and with the correct value.

However when loading the file at runtime with libglade the property
isn't set. The widget is instantiated, the property is there, but the
value is not set to what is in the .glade file. This is where the
glade_register_custom_prop function comes in: it calls a custom function
whenever the given GType/property name is found.
