add_handler_filter_vardict

Register a new channel class as Handler.

HandlerChannelFilter. The handle_channels 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 handle_channels.

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
