Hello!
Thanks for your reply.
New text (with const Cairo = imports.cairo ):
const Cairo = imports.cairo;
const Gtk = imports.gi.Gtk;
const Gdk = imports.gi.Gdk;
function draw(obj, event) {
let cr = Gdk.cairo_create(obj.window);
}
Gtk.init(null, null);
let win = new Gtk.Window({type: Gtk.WindowType.TOPLEVEL, title: "Test"});
win.connect("destroy", Gtk.main_quit);
let da = new Gtk.DrawingArea();
da.connect("expose_event", draw);
win.add(da);
win.show_all();
Gtk.main();
Result is the same
JS ERROR: !!! Exception was: Error: No exception was set, but object
construction failed somehow
JS ERROR: !!! lineNumber = '0'
JS ERROR: !!! fileName = 'gjs_throw'
JS ERROR: !!! message = 'No exception was set, but object
construction failed somehow'
JS ERROR: !!! stack = 'Error("No exception was set, but object
construction failed somehow")@:0
("No exception was set, but object construction failed
somehow")@gjs_throw:0
@:0
draw([object _private_Gtk_DrawingArea],[object
_private_Gdk_Event])@test.js:6
Error("Chained exception")@:0
("Chained exception")@gjs_throw:0
'
I did not compile packages. I used Mandriva's repository.
With best regards, Youry Harchenko.

Did you compile gjs with cairo support?
As a way of debugging, try adding let cairo = imports.cairo; before
importing Gtk and see if anything
changes.
