Como pongo las pestañas en sentido vertical???

si alguien sabe de eso pues me podria decir???

he navegado un poco y solo he encontrado a otros preguntando lo mismo y otros mas aconsejando hacer una clase heredada de component y calcular todo manualmente

Tambien he leido un omentario de alguien que escudriño en el codigo y dijo que era imposible, que eso es problema de el estilo que se le aplica a la ventana , ya saben el metal … algo
no se si sea util esa info
