Today there is a feature in the system that requires you to click a button to remove the check box in front of the tree node and make it unselected. I searched the Internet for a long time, and then I checked the API by myself. Finally I found a solution.

This is handled differently in extjs3.x and 4.x versions. In the 3.x version, you can do this:

Practice is the mother of true knowledge, encounter problems are not afraid of difficult, do not retreat, will always be solved.
