[Poppler-bugs] [Bug 94378] Implement digital signature support (qt frontends)

--- Comment #7 from Hanno Meyer-Thurow <h.mth at web.de> ---
There is one thing I just cannot wrap my head around/thinking to much:


Variant I: Do you want FormFieldSignature to return a SignatureValidationInfo
instance pointer, that the user has to delete?

Variant 2: Or should the FormFieldSignature instance manage the
SignatureValidationInfo instance, where the user gets a const instance pointer
(get and forget)?


If the SignatureValidationInfo class ever changes, application linked to old
ABI or mixing compiler ABI(name mangling), I question the proper
destruction[0][1].


Therefore I recommend variant II; expecting same c++ name mangling; keep it
simple.

How do you want it?
