Python GTK3 inheritance -


How can I get GTK + 3 class in Python? I am trying to create a legacy class of Gtk.Application and what I have found is a segfault.

I have tried a lot of things, but with this I got a segfault: 

  class program (Gtk.Application): def __init __ (self): super () .__ init __ (self) ... PRG = Program.new ("APP_ID", flags)    "post-text" itemprop = "text"> 
 If I try my code snippet, I actually get:  
  traceback (most recent call final): In the file "pyclass.py", line 12, & lt; Module & gt; PRG = Program.new ("APP_ID", 0) Writing Error: Application Maker can not be used to create examples of a subclass program   
 Which is expected, since you call Python Using the code for  gtk_application_new ()  should try the  Program.new ()   
 python manufacturer form.   class program (Gtk.Application): def __init __ (self): Gtk.Application .__ init __ (auto, APPLICATION_ID = "org.example.Foo", flags = Gio.ApplicationFlags .FLAGS_NONE) PRG = Programs () sys.exit (prg.run (sys.argv));   
 This will actually warn you that you have not implemented the  GApplication :: activate  virtual function, which can be achieved by overriding the  do_activate  Virtual method in your  program  class:  
  class program (Gtk.Application): def __init __ (self): Gtk.Application .__ init __ (self, APPLICATION_ID = "org.example.Foo", flags = Gio.ApplicationFlags.FLAGS_NONE) Def do_activate (self): print ("active!")   
 this will print < code> active  Console, before leaving.
