> Hi John,
Thanks. I can't follow all of what you said, but i get the idea.
Is there any way to achieve my purpose without the property_change() method?
The Gtk.Window().get_window() returns an object of type
gi.types.gtk.gdk.X11window. Can i do something with that?
I tried to get_properties() on it, but i had to pass an argument and could
not introspect to find out which, and i don't know if the set_property()
method would help.
Or is there a non-Gtk way to address X and reserve screen space?
Thanks
Benjamin

PyGI has removed .attributes, so the replacement to get the GdkWindow)
would be get_widget_get_window() or Gtk.Widget.get_window() from g-i.
However, property_change is annotated with (skip) in the bindings
because of the nature of the data argument - unsigned char * + length
but callers should explicitly cast other property types (that are
greater than sizeof(char)).
Its a bit of an ugly C-api, and I played with the annotations a bit. The
best g-i could do was only accept n-values between 0 - 255 and format=8.
Based on the large amount of c-code in the pygtk override for this
function, I think it might be easier to just add multiple functions to
gdk3 to replace this one
property_change_8(... const guint8 *data ...)
property_change_16(... const guint16 *data ...)
property_change_32(... const guint32 *data ...)
I suggest filing a bug with gtk.
