I'd like to add an action to my Notification with a callback. I'm using pygobject with the following code:
import logging
from time import sleep
import gi
gi.require_version('Notify', '0.7')
from gi.repository import Notify
def callback(*args, **kwargs):
print("Got callback")
print(locals())
def main():
Notify.init("Hello World")
notification = Notify.Notification.new("Testing")
notification.add_action("my action", "Submit", callback)
notification.show()
sleep(5)
if __name__ == '__main__':
logging.basicConfig(level=logging.DEBUG)
main()
When I run the script, I see the notification with the "Submit" button, but when I click the button the callback isn't run (as far as I can tell).
When I use ipython to inspect things, I get this help for add_action:
In [65]: Notify.Notification.add_action?
Type: FunctionInfo
String form: gi.FunctionInfo(add_action)
File: /usr/lib/python3.5/site-packages/gi/__init__.py
Docstring: add_action(self, action:str, label:str, callback:Notify.ActionCallback, user_data=None)
So I see that the callback should be an ActionCallback? I then inspect that class:
In [67]: Notify.ActionCallback
---------------------------------------------------------------------------
NotImplementedError Traceback (most recent call last)
<ipython-input-67-aa40d4997598> in <module>()
----> 1 Notify.ActionCallback
/usr/lib/python3.5/site-packages/gi/module.py in __getattr__(self, name)
231 wrapper = info.get_value()
232 else:
--> 233 raise NotImplementedError(info)
234
235 # Cache the newly created wrapper which will then be
NotImplementedError: gi.CallbackInfo(ActionCallback)
...and I get a NotImplementedError. So are notification actions just not implemented in PyGObject? Or am I doing something wrong in passing my callback to the add_action method?
I'm on arch linux, using the package python-gobject 3.22.0-1, running with python 3.5.2.
It turns out I needed to run the Gtk main loop:
from gi.repository import Gtk
Gtk.main()
Then the callback was called just fine
