¿Qué evento puede desencadenar a GetFocus de un control WX.Checklist?

Question

Estoy tratando de usar el enfoque de un control de la lista de verificación para proporcionar información al usuario para ayudarlos en su selección.Puedo auto.list.getfocus en un evento de un artículo de verificación, pero parece que no puede obtener el enfoque fuera de un elemento de verificación. Mi objetivo es tener la pestaña de usuario a través de la lista y, a medida que el enfoque de la lista cambia los mensajes de la barra de estado, la información de la barra de estado de la fila centrada para que el usuario esté informado.La selección de Oncheckitem se utiliza para desencadenar otra acción. ¿Alguien puede darme alguna dirección? Gracias

Aquí está el código que estoy usando:

Bueno, puede haberlo descubierto. El siguiente código, cuando se agrega a la clase de LiChLiSpannel permitirá identificar el elemento seleccionado.Supongo que el control de la lista debe ser instanciado antes de poder usar el método GetSelectectEm (), ya que requiere un WX.ID para enlazar el evento.Añadí esto después de rellenar la lista Configuración del panel Sizer

            # bind selected event to selected row
    wx.EVT_LIST_ITEM_SELECTED(self,self.list.GetId(), self.OnSelectItem)


def OnSelectItem(self, index):
    print 'Selected item index=',self.list.GetFocusedItem()
    msg='Selected item index='+str(self.list.GetFocusedItem())
    Publisher().sendMessage(('change_statusbar'), msg) # Communication with Main Frame
