gtk2/gtk/gtkfilechooserbutton.c
Matthias Clasen a811584d01 Use the new file DND api. 
2004-10-22  Matthias Clasen  <mclasen@redhat.com>

	* gtk/gtkfilechooserbutton.c (gtk_file_chooser_button_drag_data_received)
	(gtk_file_chooser_button_init): Use the new file DND api.

	* gtk/gtkdnd.h:
	* gtk/gtkdnd.c (gtk_drag_dest_add_uri_targets)
	(gtk_drag_source_add_uri_targets):

	* gtk/gtkselection.h:
	* gtk/gtkselection.c (gtk_target_list_add_uri_targets):
	(gtk_selection_data_set_uris):
	(gtk_selection_data_get_uris): New functions to allow
	handling file DND "without knowing jack shit".

	* configure.in: Bump glib requirement to 2.5.4.

	* gtk/gtkfilechooserdefault.c (shortcuts_drop_uris): Use
	g_uri_list_extract_uris().
