Description

The BonoboUIComponent is the client side portion of the UI merging scheme. It should be implemented by any component that wishes to merge menus / UI. The Component object is neccessary to receive notifications from the associated BonoboUIContainer. Notifications come in two forms - verbs and events. Verbs have an associated ( non translated ) name that is used to match them with callbacks. Events have an associated ( non translated ) id that does the same thing. Events pass a state string. Events are used for eg. toggle buttons, Verbs are used for eg. Menu items.

Mostly you don't need to bother with creating your own BonoboUIComponent, if you implement a Control eg. a BonoboUIComponent is created at Control construction time and can be accessed thus:

Example 1. Using the UI Component associated with a control

/*
 * For the format of the XML see bonobo/doc/xml-ui.txt
 * For a standard template to base your UI on see bonobo/doc/std-ui.xml
 */
const char my_ui_elements [] =
	">placeholder name=\"FileOps\"<"
	"	>menuitem name=\"Foo\" verb=\"FileFoo\" _label=\"Foo!\""
	"	 _tip=\"do some foo thing\"/<"
	">/placeholder<";

static void
control_activate_cb (BonoboControl *object,
                     gboolean       state,
 		     gpointer       user_data)
{
	BonoboUIComponent *ui_component;

	/* Get UIComponent from control */
	ui_component = bonobo_control_get_ui_component (control);

	if (state) /* Activate */
		bonobo_ui_component_set_translate (
			ui_component, "/menu/File", my_ui_elements, NULL);

	else /* De-activate */
		bonobo_ui_component_unset_container (ui_component);
}

static void
verb_foo_cb (BonoboUIComponent *ui_container,
             gpointer           user_data,
	     const              char *cname)
{
	BonoboControl *control = user_data;

	g_print ("FileFoo !\n");
}

static BonoboUIVerb my_ui_verbs[] = {
	BONOBO_UI_VERB ("FileFoo", verb_foo_cb),
	BONOBO_UI_VERB_END
};

BonoboObject *
create_ui_control (void)
{
	BonoboControl     *control;
	BonoboUIComponent *ui_component;
	GtkWidget         *widget;

	control = bonobo_control_new ((widget = gtk_widget_new_label ("Hello World")));

	/* Automaticaly associate the remote UIContainer for us on activate */
	bonobo_control_set_automerge (control, TRUE);

	ui_component = bonobo_control_get_ui_component (control);

	/* Register the verbs with the UI Component */
	bonobo_ui_component_add_verb_list_with_data (
		ui_component, my_ui_verbs, control);

	gtk_signal_connect (GTK_OBJECT (control), "activate",
	                    GTK_SIGNAL_FUNC (control_activate_cb), NULL);
	gtk_widget_show (widget);

	return BONOBO_OBJECT (control);
}
    

This sets up the UI, associates a 'FileFoo' verb with a callback, and on control activation merges the UI elements into a standard path in the file menu.

There are several standard placeholders that it is important for containers to implement, basing your UI on the doc/std-ui.xml is a very good starting point. Also in the above example the _label and _tip are not cmd / widget separated - for more information read doc/ui-xml.txt.

Most applications will should not use the BonoboUIComponent in this way, there is a bonobo_ui_util_set_ui that does the translation, help menu build, insertion etc. from an installed XML file. The above example is complete except for translation, which is extremely important. Here is a better activate function:

Example 2. A better way to create your UI

static void
control_activate_cb (BonoboControl *object,
                     gboolean       state,
		     gpointer       user_data)
{
	BonoboUIComponent *ui_component;

	/* Get UIComponent from control */
	ui_component = bonobo_control_get_ui_component (control);

	if (state) /* Activate */
		/*
		 * Use a helper function to setup your UI from a file:
		 */
		bonobo_ui_util_set_ui (
			ui_component, MY_COMPILE_TIME_PREFIX,
			"GNOME_MyApp.ui", "my-app");
	else /* De-activate */
		bonobo_ui_component_unset_container (ui_component);
}
    

In this example "GNOME_MyApp.ui" is the correctly namespaced UI xml filename, ( see doc/NAMESPACE to register your name ), and "my-app" is the gnome application name, from which a path to your installed help files can be deduced.
