I fear it's a bit more work than a week to do it properly. You can go
with logging the X ids from the application for now.

I don't know and I don't have the knowladge in this field but I think
it would be important to realize that this seems to be a major issue
for anyone who would like to do a black-box testing of the application.

I am not currently subscribed to the gtk devel list, so I don't intend
to discuss the advanced solution now.

The simple solution does not require any support though, though it is
custom to the application tested. The idea is, that for each widget in
the application that you need to manipulate from test suite, you add
code like:

$widget->signal_connect_after("realize", \&debug_realize, "widget-name")

and then the hook would be along the lines of:

sub debug_realize {
    my ($widget, $name) = @_;
    print STDERR $name . ':' . $widget->window->get_xid . "\n";

Now the test driver would read stderr of the application to find which
windows it should send the events to. You can only do it for widgets
that actually accept events -- things like labels and images don't have
their own windows. The get_xid method is for X. For Windows there should
be some other similar method.
