Root Tree State does not update

Preface: I’m not sure if this is an issue with the IPC or a feature of i3 itself but a confirmation would be nice.

If you change the attributes of a window in another workspace, the new attributes are not reflected in get_tree until that window has received focus.

Ex:

1.) Create a window in workspace 1 2.) Go to Workspace 2 3.) Open & run command in terminal 1 python shell (leave shell open)

from i3ipc import Connection
i3 = Connection()
rect = i3.get_tree().find_by_id(<id_of_wkspc1_window>).rect
print(rect.__dict__)

4.) Open & run command in terminal 2 in bash shell

i3-msg [con_id=<id_of_wkspc1_window>] resize set 75ppt 75ppt

5.) Still in workspace 2, run in terminal 1 in the same python shell

rect = i3.get_tree().find_by_id(<id_of_wkspc1_window>).rect
print(rect.__dict__)

The rect still contains the same values, even though it has been manipulated. If you now focus on workspace 1, go back to workspace 2 and rerun the same python command:

rect = i3.get_tree().find_by_id(<id_of_wkspc1_window>).rect
print(rect.__dict__)

The height and width attributes of rect are now changed… I am thinking this might be a lazy evaluation by i3 itself rather than an issue with the IPC. But maybe I am incorrect.

I have also tried reinstantiating a new Connection instance with every run to no avail.

Any advice here would be great. Thank you!

I think this test illustrates the problem

https://github.com/altdesktop/i3ipc-python/blob/0ec537d405f5327b86aee09bbdb0986dc136ff8f/test/aio/test_window.py#L76-L102

It’s very likely an issue with i3 because all the tree info is rerendered every time you call get_tree() with what the ipc gives us.

Try to reproduce the issue with i3-msg -t get_tree alone. If you do that, you can post it on the i3 tracker and it can get fixed there.
