Tengo un formulario personalizado con algunos de validación.
Uno de estos validación es si el valor de atributo es NULO. El valor de NULL representación en el QGIS es float de acuerdo a la Configuración->Opciones.
Cómo comprobar si el valor en el QLineEdit es NULA de acuerdo con el QGIS valor NULO?
Cuando sé de QGIS representación sin problemas, pero si alguien los cambios de este parámetro... oh, oh!
Im trate de esta manera:

Veo que esto de Nathan post pero no puedo poner en práctica.
