Usar temas de GTK en las aplicaciones de TKinter. No requiere ttk y funciona en KDE.

Foto de Pantalla:

De fondo Gedit en Ubuntu, usando el tema Ambiance, arriba una ventana con similar tema pero en TK, a su lado una ventana TK por defecto.

El codigo de este ejemplo esta mas abajo (la foto no esta editada, no hay truco, funciona en KDE, o inclusive lo he hecho funcionar sin GTK instalado).

Comentario personal:

Es más bonito que TTK 🙂. Como sea, la idea es aprovechar que en Linux TODO es un archivo, la magia esta en parsear.

Me gusto esta idea de usar los temas de gtk en tkinter. Pero tener que especificar el estilo de cada widget es un poco tedioso :). Asi que a continuación va una variante de la receta.

Ventajas:

  • No es necesario especificar el estilo de cada widget al crearlos.

Desventajas:

  • Requiere PyGtk.
  • No funciona con ttk.

Probado con python 2.6 y PyGtk 2.17
