1  Programación / Scripting / [SOLUCIONADO]WebKit Python PyQt4 en: 28 Febrero 2011, 20:02 pm

Hola a todos. Tengo un problemita, quiero hacer una app que pueda cargar varias paginas, la idea es que cargue una pagina en esta ventana de webkit, y al pasar un tiempo determinado por ejemplo 5 min o 10 seg lo que sea, cargue otra, el problema es que si yo hago un metodo que cargue varias paginas, solo veo cargarse la ultima que pongo, no las anteriores, esto me suena a un problema de eventos pero no he encontrado la info que necesito en internet. Espero que alguien me pueda ayudar, dejo el codigo aquí.

Muchas gracias
