如何在tkinter中的ttk.Treeview中取消选择行

Question

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?

Answer 1

更改treeview=ttk.Treeview()的名称，我使用treeview=ttk.Treeview()并在按钮[UNSELECT ALL]输入以下代码：

treeview.selection_clear()
