Subject: Add API to check if an EphyEmbed has forms with user input in them.

2004-01-04  Christian Persch  <chpe@cvs.gnome.org>

	* embed/ephy-embed.c: (ephy_embed_has_modified_forms):
	* embed/ephy-embed.h:
	* embed/mozilla/EphyBrowser.cpp:
	* embed/mozilla/EphyBrowser.h:
	* embed/mozilla/mozilla-embed.cpp:

	Add API to check if an EphyEmbed has forms with user input in them.
	Currently it required one modified textarea, or two modified text
	fields.

	* src/ephy-notebook.c: (ephy_notebook_class_init),
	(close_button_clicked_cb):
	* src/ephy-notebook.h:
	* src/ephy-window.c: (confirm_close_with_modified_forms),
	(ephy_window_delete_event_cb), (tab_delete_cb), (setup_notebook),
	(ephy_window_init), (ephy_window_remove_tab):

	When closing a window or tab, check if there is unsubmitted user
	input in form fields, and if so, warn the user before closing.
	Fixes bug #119857.
