Sets whether page contents are complete.

This will make assistant update the buttons state to be able to continue the task.

Since gtkmm 2.10:

Parameters:

	page	A page of assistant.
	complete	The completeness status of the page.

void Gtk::Assistant::set_page_header_image	(	const Widget&	page,
		const Glib::RefPtr< Gdk::Pixbuf >&	pixbuf

Parameters:

	page	A page of assistant.
	pixbuf	The new header image page.

void Gtk::Assistant::set_page_title	(	const Widget&	page,
		const Glib::ustring &	title

	title	The new title for page.

void Gtk::Assistant::set_page_type	(	const Widget&	page,
		AssistantPageType	type

	type	The new type for page.

Glib::SignalProxy0< void > Gtk::Assistant::signal_apply ( )

Prototype:: void on_my_apply()

Glib::SignalProxy0< void > Gtk::Assistant::signal_cancel ( )

Prototype:: void on_my_cancel()

Glib::SignalProxy0< void > Gtk::Assistant::signal_close ( )

Prototype:: void on_my_close()

Glib::SignalProxy1< void,Gtk::Widget* > Gtk::Assistant::signal_prepare ( )

Prototype:: void on_my_prepare(Gtk::Widget* page)

void Gtk::Assistant::update_buttons_state ( )

Forces assistant to recompute the buttons state.

GTK+ automatically takes care of this in most situations, e.g. when the user goes to a different page, or when the visibility or completeness of a page changes.

One situation where it can be necessary to call this function is when changing a value on the current page affects the future page flow of the assistant.
