tkinter使用小例子

在python中做一些小的用户交互输入输出时,场景特别简单的时候,我们可能就不是特别想引入wxpython/pyqt这样的图形框架,

那么这个时候python自带的tkinter就是个不错的选择;

下面是一个使用的小例子:

# -*- coding: cp936 -*-

import tkinter as tk

def Exas():
    global root
    root.destroy()
def center(win):
    """
    centers a tkinter window
    :param win: the root or Toplevel window to center
    """
    win.update_idletasks()
    width = win.winfo_width()
    frm_width = win.winfo_rootx() - win.winfo_x()
    win_width = width + 2 * frm_width
    height = win.winfo_height()
    titlebar_height = win.winfo_rooty() - win.winfo_y()
    win_height = height + titlebar_height + frm_width
    x = win.winfo_screenwidth() // 2 - win_width // 2
    y = win.winfo_screenheight() // 2 - win_height // 2
    win.geometry('{}x{}+{}+{}'.format(width, height, x, y))
    win.deiconify()
def main():
    global root
    root = tk.Tk()
    root.title("InstagramBot")
    # root.geometry('180x100+50+50')
    portInput = tk.StringVar()
    
    lblportInput = tk.Label(root, text = '端口:').grid(row = 0, column = 0, padx = 0, pady = 10)
    entportInput = tk.Entry(root, textvariable = portInput).grid(row = 0, column = 1)
    btn = tk.Button(root, text = '确定', command = Exas, fg='black', font='黑体 12').grid(row = 5, column = 1)
    center(root)
    root.mainloop()
    portStr = portInput.get()
    print('===',portStr)

if __name__ == "__main__":
    main()
