Dual/multi monitor support?

[markdarb]

Hi,

Is it possible to see/change which screen a window is displayed on in multi-monitor setups? I'd like to be able to do this for both fullscreen and normal windows.

The functions gtk_window_set_screen() and gtk_window_get_screen() listed at http://library.gnome.org/devel/gtk/unstable/GtkWindow.html are the sort of thing I'm looking for, but I haven't been able to find anything along those lines implemented in Gtk#.

Many thanks,
Mark.

If by *screen* you mean *monitor* and you hav a single *sceen* splitted
on 2 *monitors*, you can do this:

//This will tell you on which monitor your window is on
Gdk.Screen screen = this.Screen;
int monitor = screen.GetMonitorAtWindow (parent.GdkWindow);

//Now, you can move it at will using Move (x, y), and it's easy to get
one monitor Bounds with:
Gdk.Rectangle bounds = screen.GetMonitorGeometry (monitor);

More info on
http://www.go-mono.com/docs/index.aspx?link=T%3aGdk.Screen%2f*

hot it helps

Hi,

Thanks for your helpful replies. They've set me on the right track
nicely (and of course reminded me of the difference between a screen
and a monitor).

Mark.
