Yeah, the list already has a parent - the 'fixed'.

Subject: Problems in attaching GtkScrolledWindow to GtkList 


Hi
I am doing a project that involves the use of GtkList.
I am trying to attach scroll bars to the lists but am not very successful.
I then tried to do a simple program to see where I was going wrong ..... The program ran .. but I got this error on the console

Gtk-CRITICAL **: file gtkscrolledwindow.c: line 951 (gtk_scrolled_window_add_with_viewport): assertion `child->parent == NULL' failed.

Any Idea what is going wrong here?

Thanks in advance
David

The code is as follows:

  gtk_widget_ref (fixed1);
