In my decoder, I have registered a uint preference using: prefs_register_uint_preference(...)
On the GUI it works fine, but it allows "-1" to be input, which Wireshark converts to 4294967295.
I could apply a limit in my decoder, but that would be hidden from the user.
How can I either:
1. Force the GUI to only take unsigned numbers (which it should do, being an uint type)
or
2. Register the preference with a range (i.e. 0 to 100 inclusive) for the GUI to implement.
Thanks for any help.
