New messages creation is simply a matter of popping up a dialog and selecting
the desired syntax and message. On initialization, all mandatory fields are
created and the complete message structure is displayed in a tree format.
Each field can then be selected and its desired value set. The value entry
mechanism will change depending on the ASN.1 type selected.
The field's name, type, ASN.1 type and value are displayed. The maximum and
minimum limits are also displayed.
For deeply nested messages a display of the fields parents are also shown to
ease navigation through the message.
A find function is available to quickly select desired fields within the
message. Fields with unconfigured values can also be found in this way.
