Re: question about gtk_dialog (gtk2)

[Emmanuele Bassi <ebassi gmail com>]

You haven't specified which windowing system you're using.

If it's X11, then the position of a window is always the remit of the
window manager; the position set is a hint, which is taken into account by
the window manager itself, alongside the "this is a dialog" hint that
GtkDialog sets.

There's no toolkit-available way to say "set this window to be at the
center of the screen", unless you create a GTK_WINDOW_POPUP and thus ask
the window manager to *not* manage your window.

Ciao,
 Emmanuele.
