python - 在tkinter.treeview中选择一个单元格并获取单元格数据

Question

我想使用鼠标指针选择 tkinter.treeview() 创建的表格中的一个单元格并打印出该单元格的值。我怎样才能做到这一点？

下面是创建 tkinter.treeview 表的示例代码。在这种情况下，我想使用鼠标指针单击“机场”值之一。但是，当我单击该单元格时，会选择整行(即小部件项)。我怎样才能避免这种情况，以便得到我想要的东西？

import tkinter as tk
import tkinter.ttk as ttk

class App(tk.Frame):
    def __init__(self, parent, *args, **kwargs):
        ttk.Frame.__init__(self, parent, *args, **kwargs)
        self.tree = ttk.Treeview(parent, columns=("size", "modified"))
        self.tree["columns"] = ("date", "time", "loc")

        self.tree.column("date", width=80)
        self.tree.column("time", width=80)
        self.tree.column("loc", width=100)

        self.tree.heading("date", text="Date")
        self.tree.heading("time", text="Time")
        self.tree.heading("loc", text="Loc")
        self.tree.bind('<ButtonRelease-1>', self.selectItem)

        self.tree.insert("","end",text = "Name",values = ("Date","Time","Loc"))
        self.tree.insert("","end",text = "John",values = ("2017-02-05","11:30:23","Airport"))
        self.tree.insert("","end",text = "Betty",values = ("2014-06-25","18:00:00","Orchard Road"))

        self.tree.grid()

    def selectItem(self, event):
        curItem = self.tree.focus()
        print (self.tree.item(curItem))


if __name__ == "__main__":
    window = tk.Tk()
    app = App(window)
    window.mainloop()

感谢 Bryan Oakley 的指导，我已将 selectItem 回调修改为:

def selectItem(self, event):
    curItem = self.tree.item(self.tree.focus())
    col = self.tree.identify_column(event.x)
    print ('curItem = ', curItem)
    print ('col = ', col)

    if col == '#0':
        cell_value = curItem['text']
    elif col == '#1':
        cell_value = curItem['values'][0]
    elif col == '#2':
        cell_value = curItem['values'][1]
    elif col == '#3':
        cell_value = curItem['values'][2]
    print ('cell_value = ', cell_value)

它给了我我想要的东西。希望这个脚本能够帮助其他提出同样问题的人。
