I'm new to Gtk. I tried to create a subclass of an HBox and add it to a window, but I get a GtkWarning telling me that the assertion `GTK_IS_WIDGET()' fails on the instance of my subclass.
For example: ===code=== from gtk import Window, HBox, WINDOW_TOPLEVEL, main class FooBox(HBox): def __init__(self): pass window = Window(WINDOW_TOPLEVEL) window.add(FooBox()) window.show_all() main() ===/code=== yields a warning at "window.add()", namely "GtkWarning: gtk_container_add: assertion `GTK_IS_WIDGET (widget)' failed". This causes the widget to not be displayed in the window. I don't really understand why this is; am I missing a method call? Thanks.
