the GUI classes (TGxxx) can not yet be streamed to file
(their ClassDef's specify still 0 as version id). To be able to
stream the rest of the class containing TGxxx object mark them
as non-streamable, e.g.:
class bla : public TObject {
private:
TGTextBuffer *TBxmin; //! do not stream
...
};
Note the ! in the comment field.
In the (near) future I plan to give the GUI classes streaming capabilities
since some people asked for the feature to be able to store GUI setups to
file.
Cheers, Fons.
