Wireshark · Wireshark-dev: Re: [Wireshark-dev] proto_tree_add_item() with range_string

["Anders Broman" <a.broman@xxxxxxxxx>]

Hi,
I had a brief look some time ago and it looked
To me like it would require new FT_x:s or
That the macros VAL and TFS would have to be changed to supply
the needed functions. Is there a better way to do it?

Hi,

Yeah, that would be nice, having stuff like this:

  static const range_string rs_value[] = {
    {  0, 49, "Little" },
    { 50, 99, "Some" },
    {100,199, "Considerable" },
    {200,255, "High" },
    {  0,  0, NULL }
  };

  proto_tree_add_item(tree, hf_proto_value, tvb, offset, 1, FALSE);

  static hf_register_info hf[] = {
    { &hf_proto_value,
      { "Value", "proto.value",
        FT_UINT8, BASE_DEC,
        RS(rs_value), 0x0,
        "How much is it worth", HFILL }}
  };

+ Frame
+ Ethernet II
+ IP
+ TCP
+ Proto
  Value: High (220)

That would require weaving in the range string handling along the types
where VALS() and TFS() handling applies (FT_*INT*, and FT_BOOLEAN).
epan/proto.c comes to mind.

Thanx,
Jaap
