Ah, y casi olvidaba: ese GRegex no se va a liberar solo
g_clear_pointer (&patt, g_regex_unref);Lo haces antes del return res;

Todos los
GtkWidgets heredan deGInitiallyUnowned, evitandote la necesidad de desreferenciarlos manualmente si los empacas dentro de otroGtkWidget, por lo que incluso podrías cambiar tu código a algo como esto:Nota: Vala tiene soporte de sintaxis para
GRegex😉Usa la señal
::notifyen lugar de::key-release-eventpara obtener un evento cada vez que la propiedad:textcambia, en lugar de obtener uno cada vez que el usuario suelta una teclaEs preferible trabajar con
GtkWidgeten lugar de clases más específicasEs más idiomático que devuelvas un
GtkWidget*en lugar de unGtkGrid*Mira también de informar a los OSK de que esas entradas son para contraseñas mediante la propiedad
