我有以下代码打开文件,我想在其中将文件的路径显示为a
。
b
问题:当我多次单击Label
import Tkinter, Tkconstants, tkFileDialog
top = Tkinter.Tk()
top.resizable(width=False, height=False)
top.geometry("700x300+350+200")
def OpenOldFile():
top.filename = tkFileDialog.askopenfilename(initialdir = "/",title="Select old file")
lb2 = Tkinter.Label(text="Old File:").grid(row=2,column=1, sticky='w')
lb3 = Tkinter.Label(text=top.filename).grid(row=2,column=2, sticky='w')
def OpenNewFile():
top.filename = tkFileDialog.askopenfilename(initialdir = "/",title="Select New file")
lb2 = Tkinter.Label(text="New File:").grid(row=6,column=1, sticky='w')
lb3 = Tkinter.Label(text=top.filename).grid(row=6,column=2, sticky='w')
lb1 = Tkinter.Label(text= "Select Old file:").grid(row=1,column=1, sticky='w')
B1 = Tkinter.Button(text = "Click to open file", command = OpenOldFile).grid(row=1,column=2, sticky='w')
lb4 = Tkinter.Label(text="Select New File:").grid(row=4,column=1, sticky='w')
B2 = Tkinter.Button(text="Click to open file", command = OpenNewFile).grid(row=4,column=2, sticky='w')
top.mainloop()
打开不同的文件时,Button
B1
的文本被覆盖在以前的文字,如下面的屏幕截图所示。

您每次点击都会创建一个新标签。取而代之的是,您应该使用空白文本创建一个,然后在单击时对其进行更新。
lb3 = Tkinter.Label()
lb3.grid(row=6,column=2, sticky='w')
def OpenOldFile():
top.filename = tkFileDialog.askopenfilename(initialdir = "/",title="Select old file")
lb3.config(text=top.filename) #or lb3["text"] = top.filename
