commit 450a9f90b4a7f6c00e9aebd9fa84f9a0d7723cd3
Author: Michael Natterer <mitch gimp org>
Date: Tue Aug 6 12:17:27 2019 +0200
libgimp: add a GimpPDB class and subclass GimpProcedure as GimpPDBProcedure
The idea is that we already have a GimpProcedure object in libgimp
which has name, help, blurb, arguments, return values and everything,
so we really don't need a parallel API to query PDB procedures for
their properties.
- make run() a virtual function of GimpProcedure
- move GIMP_PDB_ERROR to GimpPDB
- GimpPDBProcedure is a trivial subblass which populates
GimpProcedure's members by querying the PDB.
- make "plug-in", "procedure-type" and "name" construct-only
properties of GimpProcedure.
This is all work in progress.
