GtkEntry does not seem to emit "notify::text-length"
GTK 4.0.3 or 4.1.1
When porting some code from GTK 3 to GTK 4, a line of the type
g_object_bind_property (entry, "text-length", button, "sensitive", G_BINDING_SYNC_CREATE);
no longer works. By connecting a handler instead, I don't see any trace of a signal being sent.
For the moment, I took this as a replacement:
g_object_bind_property (gtk_entry_get_buffer (entry), "length", button, "sensitive", G_BINDING_SYNC_CREATE);
which works fine.
