单击Tkinter TreeView小部件项的命令?

如果希望在用户双击时发生某种情况,请将绑定添加到 "<Double-1>" . 因为单击设置了选择,所以您可以在回调中查询该小部件以找出所选内容。例如:

import tkinter as tk
from tkinter import ttk

class App:
    def __init__(self):
        self.root = tk.Tk()
        self.tree = ttk.Treeview()
        self.tree.pack()
        for i in range(10):
            self.tree.insert("", "end", text="Item %s" % i)
        self.tree.bind("<Double-1>", self.OnDoubleClick)
        self.root.mainloop()

    def OnDoubleClick(self, event):
        item = self.tree.selection()[0]
        print("you clicked on", self.tree.item(item,"text"))

if __name__ == "__main__":
    app = App()

当选择多个元素并且用户使用 SHIFT+CLICK (至少在Mac电脑上)。

下面是一个更好的解决方案:

import tkinter as tk
import tkinter.ttk as ttk

class App:
    def __init__(self):
        self.root = tk.Tk()
        self.tree = ttk.Treeview()
        self.tree.pack()
        for i in range(10):
            self.tree.insert("", "end", text="Item %s" % i)
        self.tree.bind("<Double-1>", self.OnDoubleClick)
        self.root.mainloop()

    def OnDoubleClick(self, event):
        item = self.tree.identify('item',event.x,event.y)
        print("you clicked on", self.tree.item(item,"text"))

if __name__ == "__main__":
    app = App()

我知道这是旧的,但此代码还将在树视图中打印多个选定项。

def on_double_click(self, event):
    item = self.tree.selection()
    for i in item:
        print("you clicked on", self.tree.item(i, "values")[0])
