Python使用Tkinter的GUI日历示例 _PythonTkinter

先决条件：Tkinter简介
Python提供了多种开发GUI(图形用户界面)的选项。在所有的GUI方法中, Tkinter是最常用的方法。带有tkinter的Python输出了创建GUI应用程序的最快, 最简单的方法。在本文中, 我们将通过分步指南学习如何使用Tkinter创建GUI日历应用程序。
创建一个tkinter：

导入模块– tkinter
创建主窗口(容器)
将任意数量的小部件添加到主窗口。
将事件触发器应用于小部件。

让我们创建一个基于GUI的日历应用程序, 该应用程序可以显示用户给定年份的日历。
下面是实现：

# import all methods and classes from the tkinter from tkinter import *# import calendar module import calendar# Function for showing the calendar of the given year def showCal() :# Create a GUI window new_gui = Tk()# Set the background colour of GUI window new_gui.config(background = "white" )# set the name of tkinter GUI window new_gui.title( "CALENDER" )# Set the configuration of GUI window new_gui.geometry( "550x600" )# get method returns current text as string fetch_year = int (year_field.get())# calendar method of calendar module return # the calendar of the given year . cal_content = calendar.calendar(fetch_year)# Create a label for showing the content of the calender cal_year = Label(new_gui, text = cal_content, font = "Consolas 10 bold" )# grid method is used for placing # the widgets at respective positions # in table like structure. cal_year.grid(row = 5 , column = 1 , padx = 20 )# start the GUI new_gui.mainloop()# Driver Code if __name__ = = "__main__" :# Create a GUI window gui = Tk()# Set the background colour of GUI window gui.config(background = "white" )# set the name of tkinter GUI window gui.title( "CALENDER" )# Set the configuration of GUI window gui.geometry( "250x140" )# Create a CALENDAR : label with specified font and size cal = Label(gui, text = "CALENDAR" , bg = "dark gray" , font = ( "times" , 28 , 'bold' ))# Create a Enter Year : label year = Label(gui, text = "Enter Year" , bg = "light green" )# Create a text entry box for filling or typing the information. year_field = Entry(gui)# Create a Show Calendar Button and attached to showCal function Show = Button(gui, text = "Show Calendar" , fg = "Black" , bg = "Red" , command = showCal)# Create a Exit Button and attached to exit function Exit = Button(gui, text = "Exit" , fg = "Black" , bg = "Red" , command = exit)# grid method is used for placing # the widgets at respective positions # in table like structure. cal.grid(row = 1 , column = 1 )year.grid(row = 2 , column = 1 )year_field.grid(row = 3 , column = 1 )Show.grid(row = 4 , column = 1 )Exit.grid(row = 6 , column = 1 )# start the GUI gui.mainloop()
