The attached boo file shows you how you'd construct such a widget fairly
easily. Beware the particulars of needing a GdkWindow to get coordinates
from (thus the EventBox), as well as all the grabbing stuff for the
popup/popdown methods.

import System
import Gtk from 'gtk-sharp'
import Gdk from 'gdk-sharp'
class WindowToggleButton (VBox):
root_box as HBox
real_box as EventBox
fake_box as HBox
button as ToggleButton
popdown_window as Gtk.Window
datetime as System.DateTime = System.DateTime.Now
cal as Calendar
def constructor ():
root_box = HBox ()
real_box = EventBox ()
button = ToggleButton (datetime.ToString ())
button.Toggled += on_toggled
real_box.Add (button)
root_box.PackStart (real_box, true, true, 0)
PackStart (root_box, false, false, 0)
# Create our new window
popdown_window = Gtk.Window (Gtk.WindowType.Popup)
# Create our calendar widget, and hook up to the interesting
key/button events
cal = Calendar ()
cal.KeyPressEvent += def (o, args as KeyPressEventArgs):
if args.Event.Key in (Gdk.Key.Return, Gdk.Key.Escape):
popdown ()
cal.ButtonPressEvent += def (o, args as ButtonPressEventArgs):
if args.Event.Type == EventType.TwoButtonPress:
popdown ()
popdown_window.Add (cal)
private def on_toggled (o, e as EventArgs):
if button.Active:
popup ();
else:
popdown ();
private def popup ():
cal.Date = datetime
x as int
y as int
real_box.GdkWindow.GetOrigin (x, y)
popdown_window.Move (x, y)
popdown_window.ShowAll ()
# Grab foo for stealing the keyboard/input focus
Gdk.Pointer.Grab (popdown_window.GdkWindow, true,
Gdk.EventMask.ButtonPressMask |

Gtk.Global.CurrentEventTime);
Gtk.Grab.Add (popdown_window)

# Undo our grab foo
Gtk.Grab.Remove (popdown_window)

Gdk.Pointer.Ungrab (Gtk.Global.CurrentEventTime);
button.Active = false
