[ Version ( since = "0.19.10" ) ]
public void add_approver_filter_vardict (Variant filter)
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.
