i3: Bug i3 with tkinter application. I3 seems to stop replying.

Output of i3 --moreversion 2>&- || i3 --version: Binary i3 version: 4.13 (2016-11-08) © 2009 Michael Stapelberg and contributors Running i3 version: 4.13 (2016-11-08) (pid 451)to abort…) Loaded i3 config: /home/tau/.i3/config (Last modified: Mon 20 Mar 2017 10:54:15 PM -03, 545611 seconds ago)

The i3 binary you just called: /usr/bin/i3 The i3 binary you are running: i3

REPLACE: i3 version output 03/27/2017 06:28:04 AM - Additional arguments passed. Sending them as a command to i3. [{“success”:false,“parse_error”:true,“error”:“Expected one of these tokens: <end>, ‘[’, ‘move’, ‘exec’, ‘exit’, ‘restart’, ‘reload’, ‘shmlog’, ‘debuglog’, ‘border’, ‘layout’, ‘append_layout’, ‘workspace’, ‘focus’, ‘kill’, ‘open’, ‘fullscreen’, ‘sticky’, ‘split’, ‘floating’, ‘mark’, ‘unmark’, ‘resize’, ‘rename’, ‘nop’, ‘scratchpad’, ‘title_format’, ‘mode’, ‘bar’”,“input”:“version”,“errorposition”:“^^^^^^^”}]

The application below after running and one pressing ‘Return’ it should quit the application and give back focus to the previous active windows. it seems i3 stops replying to commands from the keyboard and i have to click on some container to get things working again. Replacing <Return> for all other kind of events it fails too. Notice, it fails if you replace Entry for Button too.

I have other application that depends on the correct behavior. I hope you guys have how to fix it.

Obs: if i comment self.resizable… it fails too.

from Tkinter import *

class BugI3(Tk):

    def __init__(self, title, default_data='', *args, **kwargs):
        Tk.__init__(self, *args, **kwargs)
        # when one quits the application
        # from an event it just makes i3 misbehaves
        # it cant get focus back to the previous application.
        self.bind('<Return>', lambda e: self.quit())

        self.title(title)
        self.resizable(0, 0)

        self.entry = Entry(self)
        self.entry.pack(side='left', expand=True, fill=BOTH)


if __name__ == '__main__':
    bugi3 = BugI3('Word Pass')
    bugi3.mainloop()
