Tkinter 之Grid布局

import tkinter as tk

window = tk.Tk()

# 设置窗口大小

winWidth = 600

winHeight = 400

# 获取屏幕分辨率

screenWidth = window.winfo_screenwidth()

screenHeight = window.winfo_screenheight()

x = int((screenWidth - winWidth) / 2)

y = int((screenHeight - winHeight) / 2)

# 设置主窗口标题

window.title("Grid参数说明")

# 设置窗口初始位置在屏幕居中

window.geometry("%sx%s+%s+%s" % (winWidth, winHeight, x, y))

# 设置窗口图标

window.iconbitmap("./image/icon.ico")

# 设置窗口宽高固定

window.resizable(0, 0)

frame = tk.Frame(window)

frame.place(rely=.5, relx=0.5, x=-122.5, y=-100, width=245, height=200)

# 返回参数信息

print(frame.place_info())

tk.Label(frame, text="用户名").grid(row=0)

tk.Label(frame, text="密码").grid(row=1)

username_var = tk.StringVar()

pwd_var = tk.StringVar()

tk.Entry(frame, textvariable = username_var).grid(row=0, column=1)

tk.Entry(frame, show="*", textvariable=pwd_var).grid(row=1, column=1)

photo = tk.PhotoImage(file = "./image/loading.gif")

tk.Label(frame, image=photo).grid(row = 0, rowspan=2, column=2, padx=5, pady=5)

def login():

    username = username_var.get()

    password = pwd_var.get()

    print("username=%s, password=%s" % (username, password))

tk.Button(frame, text="登录", command=login, padx=20).grid(row=2, columnspan=3)

window.mainloop()
