Log Message:

Changes to facilitate setting openvrml-player's location entry after
the world has been loaded.

Significantly, access to the GIOChannel used by the GtkVrmlBrowser
(i.e., the request channel) needed to be made thread-safe.
Accordingly, all access to the request channel now goes through the
function openvrml_xembed::write_request_chars.

+ 	Changes to facilitate setting openvrml-player's location entry
+ 	after the world has been loaded.
+ 
+ 	Significantly, access to the GIOChannel used by the
+ 	GtkVrmlBrowser (i.e., the request channel) needed to be made
+ 	thread-safe.  Accordingly, all access to the request channel now
+ 	goes through the function openvrml_xembed::write_request_chars.
+ 
+ 	* doc/openvrml-xembed.texi: Documented browser-event and world-url
+ 	requests; and add-browser-event-listener,
+ 	remove-browser-event-listener, and get-world-url commands.
+ 	* src/openvrml-player/Makefile.am (AM_CPPFLAGS): -I flags for
+ 	libopenvrml headers.  player.cpp now uses
+ 	openvrml::browser_event::type_id enumerants.
+ 	* src/openvrml-player/player.cpp
+ 	(main(int, char *[])): Factored subprocess spawning to
+ 	spawn_openvrml_xembed; made location_entry a global variable.
+ 	(get_openvrml_xembed_cmd(gint &, gchar ** &)): Get the program
+ 	name--and any user-supplied arguments--for openvrml-xembed.  The
+ 	result is an argument vector to accommodate any user-supplied
+ 	arguments in the OPENVRML_XEMBED environment variable.
+ 	(spawn_openvrml_xembed(GdkNativeWindow, gint &, gint &)): Spawn
+ 	the openvrml-xembed subprocess.
+ 	(set_locationentry_text(const gchar *)): Set the text for the
+ 	location text entry.
+ 	(openvrml_player_request_data_available(GIOChannel *,
+ 	GIOCondition, gpointer)): Added support for browser-event and
+ 	world-url requests.
+ 	* src/openvrml-xembed/Makefile.am (noinst_HEADERS): Added
+ 	request_channel.h.
+ 	* src/openvrml-xembed/gtkvrmlbrowser.cpp
+ 	(resource_fetcher): Removed request_channel_ member; removed
+ 	constructor definition (use compiler-generated default
+ 	constructor).  Removed write_request_chars member function.
+ 	(redraw_listener): Renamed browser_listener class.
+ 	(event_func_listener): openvrml::browser_listener implementation
+ 	for handling listeners registered with
+ 	gtk_vrml_browser_add_listener.
+ 	(GtkGLViewer): Added friend functions
+ 	gtk_vrml_browser_get_world_url, gtk_vrml_browser_add_listener, and
+ 	gtk_vrml_browser_remove_listener.  Added member
+ 	event_func_listener_map_.
+ 	(gtk_vrml_browser_new()): Removed GIOChannel argument.
+ 	(gtk_vrml_browser_get_world_url(GtkVrmlBrowser *)): Get the URL of
+ 	the currentl loaded world.
+ 	(gtk_vrml_browser_add_listener(GtkVrmlBrowser *,
+ 	GtkVrmlBrowserEventFunc, gpointer)): Add a browser event callback.
+ 	(gtk_vrml_browser_remove_listener(GtkVrmlBrowser *, gulong)):
+ 	Remove a browser event callback.
+ 	(resource_fetcher::do_get_resource(const std::string &)): Send
+ 	request using openvrml_xembed::write_request_chars.
+ 	* src/openvrml-xembed/gtkvrmlbrowser.h
+ 	(GtkVrmlBrowserEvent): Added enumeration.
+ 	(GtkVrmlBrowserEventFunc): Type of callback function used with
+ 	gtk_vrml_browser_add_listener.
+ 	(gtk_vrml_browser_new()): Removed GIOChannel argument.
+ 	(gtk_vrml_browser_get_world_url(GtkVrmlBrowser *)): Added
+ 	function.
+ 	(gtk_vrml_browser_add_listener(GtkVrmlBrowser *,
+ 	GtkVrmlBrowserEventFunc, gpointer)): Added function.
+ 	(gtk_vrml_browser_remove_listener(GtkVrmlBrowser *, gulong)):
+ 	Added function.
+ 	* src/openvrml-xembed/main.cpp
+ 	(event_listener_id_map): Maps a listener identifier from the host
+ 	application (i.e., from the add-browser-event-listener command) to
+ 	the corresponding listener identifier gotten from the
+ 	GtkVrmlBrowser.
+ 	(command_istream_reader::operator()() const): Handle
+ 	add-browser-event-listener, remove-browser-event-listener, and
+ 	get-world-url commands.
+ 	(openvrml_xembed_browser_event_func(GtkVrmlBrowser *,
+ 	GtkVrmlBrowserEvent, gpointer)): GtkVrmlBrowser event listener
+ 	callback function.  Sends browser-event via the request channel.
+ 	(openvrml_xembed::write_request_chars(const gchar *, gssize,
+ 	gsize*)): Lock the request_channel's mutex and write a request to
+ 	be consumed by the host application.
+ 	* src/openvrml-xembed/request_channel.h: Added file.  Declaration
+ 	of openvrml_xembed::write_request_chars.
