It seems you use BASE_HEX_DEC for the field. If you use BASE_HEX it shoudl disply only hexadecimal variant.

Předmět: Re: [Wireshark-dev] Disectors & conversations



Thanks for the info.

I have yet another question.

Using the routine proto_tree_add_item() to add a signed value to the
Protocol tree displays the value in HEX (as expected) & a decimal value
in parens.  How can I prevent the decimal value from being displayed?
