How do I take a screenshot using GdkPixbuf?

问题

Using PyGTK, I used to be able to take a screenshot using gtk.gdk.pixbuf.get_from_drawable.

I can't seem to figure out how to do that using PyGObject and GdkPixbuf. I've tried get_from_drawable and get_from_window but neither work in PyGObject.

Thanks in advance.

Use Gtk.OffscreenWindow:

offscreen_window = Gtk.OffscreenWindow()
offscreen_window.add(widget_that_needs_screenshotting)
pixbuf = offscreen_window.get_pixbuf()
