Migrating Python plug-in from Gimp 2.10

[nerudaj]

2) you can generate you own complete dialog. AFAIK you can add GimpUI elements in a regular pyGTK script.

3) see 2)

Thanks for your response. I didn't realize I can just ignore ProcedureDialog and create my own window with Gtk. If anybody else stumbles upon this thread, here's a minimal Python plugin that opens its own window:

Code:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

import gi
gi.require_version('Gimp', '3.0')
from gi.repository import Gimp
gi.require_version('GimpUi', '3.0')
from gi.repository import GimpUi
from gi.repository import GObject
from gi.repository import GLib
from gi.repository import Gtk
from gi.repository import Gegl
import sys
#import pygtk
#import gtk
