MacOS: clipboard never emits owner change signal
the quartz implementation of GdkClipboard does not emit any signal when the clipboard changes
As a matter of fact the implementation is empty:
void
_gtk_clipboard_handle_event (GdkEventOwnerChange *event)
{
}
I am guessing this is a 'know-issue', but it is probably worth having an issue trying to document the current limitations and challenges. At the moment I did not find much information on what is "todo" and what is "not done because it is not possible at all"
