Tengo un PyQT aplicación con una barra de herramientas, un conjunto de botones, y una fila inferior de botones adicionales. Me gustaría añadir un editor de texto debajo de la fila inferior que el usuario puede ocultar o mostrar. Me gustaría que el TextEdit para extender la parte inferior cuando se muestra, pero, cuando el usuario se esconde, me gustaría que la parte inferior quitar sin afectar la altura, anchura o tamaño de cualquier otro de los botones. Imagino que sólo toma un par de tijeras para el TextEdit sección cuando el usuario lo oculta, pero, a continuación, pegar la espalda cuando el usuario lo quiere de vuelta. Esto es incluso posible hacer en PyQt? Lo más cercano que he encontrado es la aplicación por debajo de la cual cambia el tamaño de todos los botones.
