Yes, you can set the value using myproperty_tree:set_text(somestring) For example: myproperty_tree:set_text(string.format("myproperty: 0x%02X", someval)) See Section 11.7.1.4 of the Wireshark Developer's Guide[1]. - Chris [1]: https://www.wireshark.org/docs/wsdg_html_chunked/lua_module_Tree.html#lua_class_TreeItem From: Wireshark-users [mailto:wireshark-users-bounces () wireshark org] On Behalf Of Pawlowsky, Marc Sent: Wednesday, September 19, 2018 9:46 AM To: wireshark-users () wireshark org<mailto:wireshark-users () wireshark org> Subject: [Wireshark-users] LUA set value for treeitem Is there a way to set the value for a treeitem after the tree item has been created? The problem: I am writing a X.409 based decoder (similar ASN.1). I have a property stored as an integer to decode. I come up with a tree like: n Myproperty o X.409 Integer ? Tag ? Length ? Value The length of the value field is variable. I have a protofield for all treeitems. For my property I am currently using pf_myproperty = ProtoField.uint8("myprop.myproperty ", "myproperty", base.HEX) I create the myproperty treeitem first, then drill down and create the treeitems underneath it. To prevent the protofield from decoding nonsense I am setting the value explicitly local myproperty_tree = tree:add(pf_myproperty, buffer(offset), 0) After all the tree items are created I can set the length using myproperty_tree::set_len(len) Is there a way I can set the value after creation? I want to be able to filter on myproperty. Something like myprop.myproperty==0xFF I cannot find anything in https://www.wireshark.org/docs/wsdg_html_chunked/lua_module_Tree.html Thanks Marc CONFIDENTIALITY NOTICE: This message is the property of International Game Technology PLC and/or its subsidiaries and may contain proprietary, confidential or trade secret information.
