如果您希望用户双击时发生某些事情，请向添加一个绑定
"<Double-1>"。由于单击可以设置选择，因此您可以在回调中查询小部件以找出选择的内容。例如：
import tkinter as tkfrom tkinter import ttkclass 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()
