[Mono-devel-list] Serializing widgets with C#

You could use [Serializable] in your class and implements ISerialiable.

So, you are not going to serialize all the widgets, instead you are
going to serialize the info needed to build it again (implementing
GetObjectData and a constructor defined in ISerializable).

in GetObjectData you are going to tell to the serialization engine
what info do you need to save, for example the text for labels, or
buttons, etc.

In the constructor you'll read the data that the serialization engine
gives you, and it'll be your responsability to bouild all the widgets

I hope that this could be useful.
