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:
//////////////////////////////////////////////////////////////////////////////////////////////////
GtkWidget * create_window1 (void)

(GTK_WINDOW_TOPLEVEL);
gtk_object_set_data (GTK_OBJECT (window1), "window1", window1); gtk_window_set_title (GTK_WINDOW (window1), "window1"); fixed1 = gtk_fixed_new ();
gtk_widget_ref (fixed1); gtk_object_set_data_full (GTK_OBJECT (window1), "fixed1", fixed1, (GtkDestroyNotify) gtk_widget_unref); gtk_widget_show (fixed1); gtk_container_add (GTK_CONTAINER (window1), fixed1); list2 = gtk_list_new ();
