file and dir lists in an other window?

[A Dark Elf <drow DarkElf net>]

I want to take the dir_list and file_list of the file selection widget and
add them to an other window. I've tried the following code but it doesn't
work. I can't seem to remove the 2 widgets from their parents to be able
to add them to my frame:


project_struct = gtk_file_selection_new("PROJECT STRUCT");

gtk_container_remove(GTK_CONTAINER(GTK_FILE_SELECTION(project_struct)->dir_list->parent),
GTK_WIDGET(GTK_FILE_SELECTION(project_struct)->dir_list));

gtk_container_remove(GTK_CONTAINER(GTK_FILE_SELECTION(project_struct)->file_list->parent),
GTK_WIDGET(GTK_FILE_SELECTION(project_struct)->file_list));

gtk_box_pack_start(GTK_BOX(vbox),
GTK_FILE_SELECTION(project_struct)->dir_list, TRUE, TRUE, 0);

gtk_box_pack_start(GTK_BOX(vbox),
GTK_FILE_SELECTION(project_struct)->file_list, TRUE, TRUE, 0);

gtk_signal_connect (GTK_OBJECT(GTK_FILE_SELECTION(project_struct)->file_list),
 "select_row", GTK_SIGNAL_FUNC(CB_project_click), project_struct);

gtk_widget_show(GTK_FILE_SELECTION(project_struct)->dir_list);
gtk_widget_show(GTK_FILE_SELECTION(project_struct)->file_list);


I get these errors:

Gtk-CRITICAL **: file gtkwidget.c: line 3300 (gtk_widget_set_parent):
assertion `GTK_IS_WIDGET (widget)' failed.

Gtk-WARNING **: invalid cast from `(unknown)' to `GtkObject'

Gtk-CRITICAL **: file gtkwidget.c: line 1642 (gtk_widget_realize):
