Is there an easy way to amend the display text for an item inserted in a
tree with proto_tree_add_item(). Like proto_item_append_text() but I
need to insert text into or in front of the existing text. For example,
if I want to display an array of items that all use the same hfindex.
In the following example, the "user" comes from hf[] and the following
name is the value.
User: Bob
User: Tom
User: Fred
I want to insert an index to the view so it would look like
User[0]: Bob
User[1]: Tom
User[2]: Fred
Unfortunately, there's currently no way to do that - and there's no
proto_tree_add_item_format() for that; you could use the other
proto_tree_add_XXX_format() routines.
This sort of thing is - "arrays" or sequences of entries of the same
type - is, I suspect, common enough that we might want to have a
mechanism to add an item and have a "subscript" added to it.
That might be a variant of the proto_tree_add_XXX routines that takes a
subscript value, and adds the subscript value after the field name - for
example, proto_tree_add_XXX_array_element() or
proto_tree_add_XXX_sequence_element().
If we did that, would we want the format of the subscript to be wired in
(e.g., "Field[n]" or "Field n"), would we want it to be a property of
the field (in the hf[] entry), or would we want it to be an additional
argument to the proto_tree_add_XXX_... routine?
I thought that if I put sprintf context into the hf[] data like
"User[%d]",
No, that's just a field name.
