add_approver_filter_vardict

Register a new channel class as Approver.

ApproverChannelFilter. The add_dispatch_operation virtual method will be called whenever a new channel's properties match the ones in filter.

This method may only be called before register is called, and may only be called on objects whose class implements add_dispatch_operation.

If the variant is floating (see g_variant_ref_sink), ownership will be taken. See add_observer_filter_vardict for more details.

Parameters:

this	a client
filter	a variant of type VARDICT
