[ruby-gnome-users-en] Gtk::Widget.remove

[Matthias V. <mat...@ya...>]

Hi,

I try to build a window, with changeable content. To achieve this,
I have defined some widgets that are made visible inside a container
- each at a time. Assume this:

predefined_widget1 = ...
predefined_widget2 = ...
window = Gtk::Window.new(Gtk::WINDOW_TOPLEVEL)
window.add(predefined1)
window.show

later I will do that:

window.delete(predefined1)
window.add(predefined2)

Now, the gtk object predefined1 is destroyed, what is really not
intended, because it shall be possible to add predefined1 to window
again - what is not possible.

This situation works in C only, if I ref (gtk_widget_ref) predefined1
before delete - but there is no pendant in ruby-gtk.
Because I have a valid ruby-reference, this is not really straight.

Do I make something wrong?
Gets every gtk-object destroyed, while its ruby wrapper is finalized?
- then a simple ref, before delete is a fast solution.

Best regards,
Matthias
