無法單擊 tkinter 上的按鈕

Question

我是 tkinter 的新手，我在使用 python GUI 上的按鈕時遇到問題。 我創建了按鈕和它后面的 function 但我無法單擊按鈕。 有人可以告訴我我做錯了什么嗎？ 用戶界面出現，我可以看到我無法點擊的按鈕。

import tkinter as tk

from tkinter import filedialog, Text

import os


#main
root = tk.Tk()

def addApp():
    filename = filedialog.askopenfilename(initialir= "/", title= "Select File",
                                          filetypes = (("executables", "*.exe"),
                                                        ("all files", "*.*")))

canvas = tk.Canvas(root, height=700, width=700, bg="#33F9FF")

canvas.pack()

frame = tk.Frame(root, bg="white")
frame.place(relwidth=0.8, relheight=0.8, relx = 0.1, rely = 0.1)

openFile = tk.Button(root, text = "Open File", padx = 10, pady = 5, fg="black",
                     bg="#33F9FF", command="addApp")

openFile.pack()

runApps = tk.Button(root, text = "Run Apps", padx = 10, pady = 5, fg="black",
                    bg="#33F9FF")

runApps.pack()

root.mainloop()

Answer 1

非常，小錯誤。 您將命令參數添加為字符串而不是 function

openFile = tk.Button(root, text = "Open File", padx = 10, pady = 5, fg="black",
                     bg="#33F9FF", command=addApp)

編輯：openfiledialogbox 中的initialdir參數有一個小錯字

filename = filedialog.askopenfilename(initialdir= "/", title= "Select File",
                                          filetypes = (("executables", "*.exe"),
                                                        ("all files", "*.*")))

還有一個錯誤：

def addApp():
    filename = filedialog.askopenfilename(initialdir= '/', title= "Select File",
                                          filetypes = (("executables", "*.exe"),
                                                        ("all files", "*.*")))
