Re: [evolution-patches] patch for 48998

Thank you, Michael

I think the function mail_account_gui_signal_connect is just ok.
If we move its content to the right place in mail_account_gui_setup, then this mail_account_gui_setup is too long and puzzled.
I use this function to complete this signal connect action and so I think it can be a separate module.

Other parts have been changed following your advices.
Please see if this one is ok.

Best Regards
Charles Zhang

Thanks Charles, this looks a lot better.

One small style thing - in the mail code we'd prefer you used function
calls directly rather than the signal connection macro, and i'm not sure
you really need mail_account_gui_signal_connect to be another function,
since its only ever called from mail_account_gui_setup anyway.

Thank you
       Following your advices, this time I have created some functions
on different object to complete encapsulating.
       And avoid unnecessary passing of toplevel widget.
       But I have to use connect serveral signals on some widget,
because these handlers need different data, so different arguments.
       Or should I alter the argement(i.e. pass a struct as argument)
of the very existing function? I think that can I be able to merge the
existing handler and the change signal handler together on the same
widget?
       Please spare some time to see if this patch meet us.
