2）Tkinter界面化小程序2.1 附源码项目

from tkinter import ttk import os import tkinter.messagebox as message_box windows = tkinter.Tk() windows.title("Python定时关机") # window 居中 windows.update() # update window ,must do curWidth = 280 # get current width curHeight = windows.winfo_reqheight() # get current height scnWidth, scnHeight = windows.maxsize() # get screen width and height # now generate configuration information config = '%dx%d %d %d' % (curWidth, curHeight, (scnWidth - curWidth) / 2, (scnHeight - curHeight) / 2) windows.geometry(config) # root 容器 root = ttk.LabelFrame(windows, text="关机命令") root.grid(column=0, row=0, padx=15, pady=15) # 提醒文本 tkinter.Label(root, text="输入时间").grid(column=0, row=0, sticky=tkinter.W) tkinter.Label(root, text="选择").grid(column=1, row=0) # 存储输入的值 time = tkinter.StringVar() unit = tkinter.StringVar() # 输入框 time_edit = tkinter.Entry(root, width=10, textvariable=time) time_edit.grid(column=0, row=1, padx=4, sticky=tkinter.W) time_edit.focus() # 下拉单位选择 unit_arr = ('时', '分', '秒') unit_chosen = ttk.Combobox(root, width=6, textvariable=unit, state='readonly') unit_chosen['values'] = unit_arr unit_chosen.grid(column=1, row=1) unit_chosen.current(0) def change_edit(to_time): time_edit.delete(0, 10) time_edit.insert(0, to_time) unit_chosen.current(1) # start def start(): if time.get() and unit.get(): message_box.showwarning("选择完毕", "你的电脑将在多少 %s %s" % (time.get(), unit.get())) # shutdown 的秒数 count_down_second = int(time.get()) if unit.get() == 'hour': count_down_second *= 3600 elif unit.get() == 'minute': count_down_second *= 60 # execute os.system("shutdown -s -t %s" % count_down_second) windows.quit() # cancel def cancel(): os.system("shutdown -a") windows.quit() # start 按钮 start_action = tkinter.Button(root, text="START", command=start) start_action.grid(column=2, row=1) # 文本 tip_label = tkinter.Label(root, text="倒计时关机") tip_label.grid(row=2, column=0, pady=2) # 快捷选择时间 fram = tkinter.Frame(root) fram.grid(row=3, column=0, columnspan=3) # 常用的时间 for i in range(2, 7): button = tkinter.Button(fram, text=str(i * 15) "min", command=lambda x=i: change_edit(str(x * 15))) button.grid(row=0, column=i - 2, padx=2, pady=2, sticky=tkinter.W) # cancel 按钮 cancel_action = tkinter.Button(root, text="CANCEL", command=lambda: cancel()) cancel_action.grid(row=4, column=1, pady=10, sticky=tkinter.W)2.2 效果展示
