Block a signal for a hierarchy of widget

[Emmanuel Pacaud <emmanuel gnome org>]

Hi,

Is there a way to unblock/block the emission of signals for a hierarchy 
of widgets ?

The reason I'm asking is because of this sort of code I'm using:

https://github.com/AravisProject/aravis/blob/master/viewer/arvviewer.c#L588

It is not very convenient and error prone to register every connected 
signals and block/unblock them when one want to update some widgets 
programmatically.

        Cheers,

                Emmanuel.
