re: re: How do I use the fullscreen in a Gtkmm app?

Thanks so much, Carlos.  This was exactly what I needed.

In Gtkmm:
Gtk::Window has the methods fullscreen and unfullscreen.  Perfect.

Rather than using a bool of my own to track the state, I did what the docs
on fullscreen() suggested and set a function to be signaled when the windows
state changed.

LXMainWindow::LXMainWindow()
{
<snip>
    m_bFullScreen = false;
    signal_window_state_event().connect(sigc::mem_fun(*this,
&LXMainWindow::OnWindowStateEvent));
}

void LXMainWindow::ToggleFullScreen()
{ // Toggle fullscreen mode off and on.
    if (m_bFullScreen))
        unfullscreen();
    else
        fullscreen();
}

bool LXMainWindow::OnWindowStateEvent(
    GdkEventWindowState* pEvent) // [in] from system -- has flags of current
state
{
    m_bFullScreen = (pEvent->new_window_state &
GDK_WINDOW_STATE_FULLSCREEN);

    return true; // we want to keep getting this signal
}

Thanks again.  Happy coding!
