Re: [API 2.4] Tooltip position

[Yann Leydier <yann leydier info>]

(question at the bottom)

Replying to my own question for people who might have the same problem 
in the future:

1) set a custom tooltip window "tipwin"
2) in bool on_query_tooltip(int x, int y, bool keyboard_tooltip, const 
Glib::RefPtr<Gtk::Tooltip>& tooltip) :
int rx, ry;
text_view.get_window(Gtk::TEXT_WINDOW_WIDGET)->get_root_coords(x, y, rx, 
ry); // this can work with the Gdk::Window of any widget
tipwin.move(rx, ry);
3) if you change the content of your tooltip, you might want to call 
tipwin.resize(1, 1) to fit the window to its content.

When setting a custom tooltip window, it seems that the argument tooltip 
is not added to the window and therefore is useless.

When not setting a custom tooltip window, the get_tooltip_window() 
method always return NULL, whereas the doc tells "This can be the 
GtkWindow created by default".
Is this a bug or a mistake in the doc ?
