# Notification implementation for Windows

Notification implementation for Windows.
Current state (2018/05/01 ELL):
 - I can't get pywin32 to work in msys2 (the platform used for this python3/gtk3 installer)
   so existing code using COM doesn't work.
 - Gio.Notification is not implemented on windows yet.
   see https://bugzilla.gnome.org/show_bug.cgi?id=776583
 - Gtk.StatusIcon with a context works but is deprecated. Showing a balloon using set_tooltip_markup
   doesn't work.
   See https://github.com/afiskon/py-gtk-example
 - in-app notifications using an overlay are pleasing to the eye, but don't solve the problem
   see https://stackoverflow.com/questions/45431512/gtk-in-app-notifications-api-referece
 - hexchat have implemented a solid c++ solution.
   See https://github.com/hexchat/hexchat/tree/master/src/fe-gtk/notifications
I've chosen to implement a cheap workaround using gtk.MessageDialog because
Gio.Notification will likely be implemented in 6 months-1 year
