Python 3.4 / GTK / Async - pygtk

Question

I use tkinter with a async funktion.
Now I will use gtk3 in stead of tkinkter.
Is there also a way to run my async function?
How should I adapt the code
Here are some code fragments:
async def _event_loop(app, interval=0.05):
try:
while True:
app.update()
await asyncio.sleep(interval)
except tkinter.TclError as exc:
if "application has been destroyed" not in exc.args[0]:
raise
class SSHFrame(tkinter.Frame):
def __init__(self, parent):
super().__init__(parent)
...
...
async def _run(self, host, command, user, password):
try:
async with asyncssh.connect(host, username=user, password=password,
client_keys=None) as conn:
self._proc = await conn.create_process(command,
term_type='dumb')
while not self._proc.stdout.at_eof():
self._output(await self._proc.stdout.read(1024))
self._output('\n[Disconnected]\n')
except (asyncssh.Error, OSError) as exc:
self._output('[%s]\n' % str(exc))
finally:
self._proc = None
class App(tkinter.Frame):
def __init__(self, parent):
super().__init__(parent)
...
...
asyncio.get_event_loop().run_until_complete(_event_loop(App(tkinter.Tk())))

import asyncio

from gi.repository import Gtk, GLib
#asyncio.coroutine
def start(app):
yield from asyncio.sleep(0)
app.register()
app.activate()
def glib_update(main_context, loop):
while main_context.pending():
main_context.iteration(False)
loop.call_later(.01, glib_update, main_context, loop)
if sys.platform == "win32":
from asyncio.windows_events import ProactorEventLoop
loop = ProactorEventLoop()
asyncio.set_event_loop(loop)
else:
loop = asyncio.SelectorEventLoop()
asyncio.set_event_loop(loop)
# This is just a fake gtk appliaction here, you should create your own see

my_gtk_app = Gtk.Application()
try:
main_context = GLib.MainContext.default()
asyncio.async(start(my_gtk_app))
glib_update(main_context, loop)
loop.run_forever()
finally:
loop.close()
