Glib::ListHandler uses a type traits class. It's a second template
argument with a default value. The default type traits class is not
suitable for your case, even though it might be considered the most
elementary case: Convert a std::vector<T*> to GList with T* elements.
First decide if you will use GdaServerOperationCreateTableArg pointers
directly in libgdamm, or if you want to to wrap them in a
Gda::ServerOperationCreateTableArg class. Then make a type traits class
suitable for either std::vector<GdaServerOperationCreateTableArg*> or
std::vector<Gda::ServerOperationCreateTableArg>. You can find some
examples of type traits classes in glibmm/gio/src/resolver.ccg,
gtkmm/gtk/src/iconview.hg, gtkmm/gtk/src/papersize.hg.
RefPtr is not useful here. It contains a pointer to a C++ object with
reference() and unreference() methods.

Dear Kjell.
I tried your suggestions and some problems are gone. However, I see
some type conversion issue. It looks like
_GdaServerOperationCreateTableArg type is not visible. I tried using
RefPtr instead of plain pointers - same effect. I attached g++ output
and patch. Thanks for any comments.

hi,
I found some mistakes in my code and fixed them. However, I can't
figure out where is the problem. I included new patch for my
changes as
well as log from the compiler. Could someone take a look?
Thanks.
The description of gda_server_operation_prepare_create_table() says
that
the "arguments" parameter is a list of
GdaServerOperationCreateTableArg,
but if you look at the code in gda-server-operation.c, you'll see
that
it's really a list of GdaServerOperationCreateTableArg*, i.e. a list
of
pointers. GdaServerOperationCreateTableArg is defined in
gda-server-operation.c, hidden from your code. You must use a
std::vector<GdaServerOperationCreateTableArg*>.
