Re: [ruby-gnome2-devel-en] Trying to get xid on gtk3 (3.1.1)

[cedlemo <ce...@gm...>]

Hi John,

It seems that it is not yet supported in the Gdk gem. Maybe we will just 
have to create a GObjectIntrospection
loader for GdkX11.


grep get_xid /usr/share/gir-1.0/*

/usr/share/gir-1.0/GdkX11-2.0.gir:    <function name="x11_drawable_get_xid"
/usr/share/gir-1.0/GdkX11-2.0.gir: c:identifier="gdk_x11_drawable_get_xid">
/usr/share/gir-1.0/GdkX11-3.0.gir:      <method name="get_xid" 
c:identifier="gdk_x11_window_get_xid">
/usr/share/gir-1.0/Wnck-3.0.gir:      <method name="get_xid" 
c:identifier="wnck_application_get_xid">
/usr/share/gir-1.0/Wnck-3.0.gir:      <method name="get_xid" 
c:identifier="wnck_window_get_xid">


Could you open an issue in github :
