how to UNSELECT row in a ttk.Treeview in tkinter

问题

Once I click into a ttk.Treeview() and select a row, I can click another row but there is no way for me to UNSELECT all the rows, there will always be at least 1 row selected. is there a clever way to allow unselecting the last selected row?

Change the name of your var i use treeview=ttk.Treeview() and put in a button [UNSELECT ALL] the following code:

treeview.selection_clear()
