[Gtk-sharp-list] using Gnome.About

[jeroen]

Hi,

It's normal for applications to only show 1 GnomeAbout dialog at a time.
So selecting Help->About again, show only raise an existing dialog.

In C, this is usually accomplished by adding a weak pointer to the about
GObject:

	g_object_add_weak_pointer (G_OBJECT (about), (gpointer *)&about);

The above call will set the about pointer to NULL when the GnomeAbout
instance is destroyed (?).

I haven't found a similar way to do this in Gtk# so far. The problem is
that once you have created a Gnome.About object, about.Visible will still
returns true even though the dialog has already been closed. The following
about.Show () call will throw a native exception.

What's the proper way of doing this in C#/Gtk#?

Thanks,

Jeroen
