Yesterday I tried to clear the content of a ComboBoxText instance. I assumed that I can do it with GtkEditable.setText(NULL) which seems to fail.
Questions: In Gtk.ComboBoxText, should GtkEditable be listed as an implemented interface? Only GtkCellEditable is listed. And is it expected that using setText() on a ComboBoxText instance with NULL for string parameter would crash? Well it is not advertised that it would work, for some other GTK functions NULL as agument work, so it took me some time to find the issue. No problem of course, I will pass an empty string.
