Python中GUI编程中常见的问题及解决方法

from tkinter import *
 
root = Tk()
 
# 使用Grid布局方式
label1 = Label(root, text="Label 1")
label1.grid(row=0, column=0)
 
label2 = Label(root, text="Label 2")
label2.grid(row=0, column=1)

# 使用Pack布局方式
label3 = Label(root, text="Label 3")
label3.pack()

label4 = Label(root, text="Label 4")
label4.pack()
 
root.mainloop()

from tkinter import *
 
root = Tk()
 
def button_click():
    print("Button clicked")
 
button = Button(root, text="Click Me", command=button_click)
button.pack()

root.mainloop()

from threading import Thread
from tkinter import *
 
root = Tk()
 
def long_time_operation():
    # 进行耗时操作
    print("Doing long time operation")
 
def button_click():
    thread = Thread(target=long_time_operation)
    thread.start()
 
button = Button(root, text="Click Me", command=button_click)
button.pack()
 
root.mainloop()

from tkinter import *
from tkinter import messagebox
 
root = Tk()
 
def show_message():
    messagebox.showinfo("Message", "Hello World")
 
menu = Menu(root)
menu.add_command(label="Show Message", command=show_message)
root.config(menu=menu)
 
root.mainloop()
