I have some python2 code that I'im migrating to python3 as python2 will reach EOL soon. And in so doing I'm also migrating from gtk2 to gtk3 via GIR. However, I am unable to find any proper documentation on how to do so.

I have the following snippets in my code that I'd like to change:

pixbuf = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB,False,8,width,height)

pixbuf.get_from_drawable(
gtk.gdk.get_default_root_window(),
gtk.gdk.colormap_get_system(),
0,0,0,0,
width,height)

pixbuf.save(...)

gtk.gdk.screen_width()

gtk.gdk.screen_width()

I came across https://lazka.github.io/pgi-docs/ and https://developer.gnome.org/pygtk/stable/class-gdkpixbuf.html, but I'm kinda new to python and GTK and am not able to figure out the equivalent transformations

Any references to documentation would help too.

You will find the replacement class for GdkPixbuf here:

For the changes from GTK+ 2 to GTK+ 3, they are mostly documented in the C documentation, unless I overlooked something.

You'll find a tutorial on GTK+ 3 with python here:

  • sifting through all that definitely wasn't easy. But I managed to get it done once I realized The code snippets I used were basically taking a screenshot. Found that here: https://stackoverflow.com/questions/20816280/pygtk3-pygobject-to-create-screenshot. Thanks anyway – Rohit Sukumaran Feb 27 '19 at 06:35
  • Sorry, I thought that you knew you were taking a screenshot. That's basically what getting the root window and saving the pixels in it is. – liberforce Feb 27 '19 at 09:13
  • This isn't my code and I just needed to do the migration. But thanks for the references @liberforce. I will need it now. – Rohit Sukumaran Feb 28 '19 at 10:35
