You can group fields in whatever way makes sense for your protocol, it doesn't always have to be flat or a "real" field (or a "real" structure). I would think that you would just call proto_tree_add_subtree() and pass it the title of <svec-list> or <request-list>. You may have to call proto_item_set_len later on the proto_item* populated by proto_tree_add_subtree() so that the bytes are correctly highlighted. -----Original Message----- From: Simon Zhong <szhong.jnpr () gmail com> To: wireshark-dev <wireshark-dev () wireshark org> Sent: Tue, Sep 30, 2014 8:59 am Subject: [Wireshark-dev] 'Virtual' subtree Hi, I'm working on PCEP dissector, I'm wonder if it's possible to create a 'virtual' subtree. The format of a message is as follows: <PCReq Message>::= <Common Header> [<svec-list>] <request-list> where: <svec-list>::=<SVEC>[<svec-list>] <request-list>::=<request>[<request-list>] <request>::= <RP> <END-POINTS> [<LSPA>] [<BANDWIDTH>] [<metric-list>] [<RRO>[<BANDWIDTH>]] [<IRO>] [<LOAD-BALANCING>] ... As you can see there's no real field called <svec-list> or <request-list>, it's just set of some other real fields. But I believe it will be more clear if we can present these real fields under a 'virtual' subtree, instead of presenting them flatly. Is there any way to do this? Thanks. /Simon ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
