/**
* SECTION:hildon-edit-toolbar
* @short_description: Widget representing a toolbar for editing.
*
* The #HildonEditToolbar is a toolbar which contains a label and two
* buttons, one of them being an arrow pointing backwards.
*
* The label is a description of the action that the user is supposed
* to do. The button is to be pressed when the user completes the
* action. The arrow is used to go back to the previous view
* discarding any changes.
*
* Note that those widgets don't do anything themselves by default. To
* actually peform actions the developer must provide callbacks for
* them.
*
* <example>
* <title>HildonEditToolbar example</title>
* <programlisting>
* GtkWidget *window;
* GtkWidget *vbox;
* GtkWidget *toolbar;
* // Declare more widgets here ...
* <!-- -->
* window = hildon_stackable_window_new ();
* vbox = gtk_vbox_new (FALSE, 10);
* toolbar = hildon_edit_toolbar_new_with_text ("Choose items to delete", "Delete");
* // Create more widgets here ...
* <!-- -->
* gtk_container_add (GTK_CONTAINER (window), vbox);
* gtk_box_pack_start (GTK_BOX (vbox), toolbar, FALSE, FALSE, 0);
* // Pack more widgets here ...
* <!-- -->
* g_signal_connect (toolbar, "button-clicked", G_CALLBACK (delete_button_clicked), someparameter);
