I have this exact same problem in Gaupol, where I have a notebook, which contains scrolled windows and inside tree views. I have looked for the cause, but haven't found it. The vague warning doesn't tell which widget is the problem and I haven't found any solution via calling the implied gtk_widget_get_preferred_width/height().
The only thing I have learned is that the amount of those error messages depends on the amount of rows in the tree view. If I have one row, I get one error message, if a thousand rows, maybe twenty error messages. Other than that it's mystery. I don't see any actual problems, but I too would like to get rid of all that junk in the console. -- Osmo Salomaa <otsal...@iki.fi> _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
