How can I get the half-checked nodes when I used the Q-Tree?

[易道]

Anybody give some suggestions？
Thanks in advance

@易道 I would also be interested to know how. I can not find a good way of getting to the data.
Here is my attempt at it. But update:ticked fires before the computed property meta changes.

Thanks a million.It was a great attempt.
emmm,It’s sure we can filter the half checked nodes by v.indeterminate.
And the question changed to : How can I get the meta that was changed at anytime?
Best regards
