Python GUI编程：案例结合Tkinter和wxPython两种用法

学习了两种GUI模块，下面我们串接起前面的内容来创建一个登陆+注册+写日记的图形用户界面。本节的设计思路为：首先通过一个主页面来控制登录界面（这是一种常用的设计理念，使主页面更为简洁），在登录页面控制两个页面，如果登录信息正确，那么跳转到下一个页面，若要注册也则点击进入注册页面，本节会通过四个代码，三个页面来简单实现。

1. 主页面程序（main.py）

123456 from tkinter import * from LoginPage import * root = Tk() root.title( '小程序' ) Login(root) root.mainloop()

2. 登陆页面程序(LoginPage.py)

123456789101112131415161718192021222324252627282930313233 from tkinter import * from tkinter.messagebox import * from MainPage import * from Register import * class Login( object ): def __init__( self , master = None ): self .root = master # 定义内部变量root self .root.minsize( 300 , 200 ) self .username = StringVar() self .password = StringVar() self .create() def create( self ): self .page = Frame( self .root) # 创建Frame self .page.pack() Label( self .page).grid(row = , stick = W) Label( self .page, text = '账户: ' ).grid(row = 1 , stick = W, pady = 10 ) Entry( self .page, textvariable = self .username).grid(row = 1 , column = 1 , stick = E) Label( self .page, text = '密码: ' ).grid(row = 2 , stick = W, pady = 10 ) Entry( self .page, textvariable = self .password, show = '*' ).grid(row = 2 , column = 1 , stick = E) Button( self .page, text = '登陆' , command = self .loginCheck).grid(row = 3 , stick = W, pady = 10 ) Button( self .page, text = '注册' , command = self .regis).grid(row = 3 , column = 1 , stick = E) def loginCheck( self ): if self .username.get() = = 'qy' and self .password.get() = = '123456' : self .page.destroy() MainPage( self .root) else : showinfo(title = '错误' , message = '账号或密码错误！' ) def regis( self ): self .page.destroy() app = wx.App() frame = MyFrame() frame.Show() app.MainLoop()

3. 注册页面程序(Register.py)

123456789101112131415161718192021222324252627282930313233343536373839 import wx class MyFrame(wx.Frame): def __init__( self ): wx.Frame.__init__( self , None , - 1 , "登录界面" , size = ( 300 , 300 )) panel = wx.Panel( self ) #创建一个画布，然后创建功能区并放到画布上 self .title = wx.StaticText(panel,label = '注册界面' ) self .username = wx.StaticText(panel,label = '用户名字:' ) self .user_name = wx.TextCtrl(panel,style = wx.TE_LEFT) self .userpassword = wx.StaticText(panel,label = '输入密码:' ) self .user_password = wx.TextCtrl(panel,style = wx.TE_PASSWORD) self .userpassword1 = wx.StaticText(panel,label = '确认密码:' ) self .user_password1 = wx.TextCtrl(panel,style = wx.TE_PASSWORD) self .button_register = wx.Button(panel,label = '注册' ) container_one = wx.BoxSizer(wx.HORIZONTAL) # 创建一个box容器并控制水平排列 container_one.Add( self .username,proportion = ,flag = wx. ALL ,border = 7 ) container_one.Add( self .user_name,proportion = 1 ,flag = wx. ALL ,border = 7 ) container_two = wx.BoxSizer(wx.HORIZONTAL) # 创建一个box容器并控制水平排列 container_two.Add( self .userpassword,proportion = ,flag = wx. ALL ,border = 7 ) container_two.Add( self .user_password,proportion = 1 ,flag = wx. ALL ,border = 7 ) container_four = wx.BoxSizer(wx.HORIZONTAL) # 创建一个box容器并控制水平排列 container_four.Add( self .userpassword1,proportion = ,flag = wx. ALL ,border = 7 ) container_four.Add( self .user_password1,proportion = 1 ,flag = wx. ALL ,border = 7 ) container_three = wx.BoxSizer(wx.HORIZONTAL) # 创建一个box容器并控制水平排列 container_three.Add( self .button_register,proportion = ,flag = wx.ALIGN_CENTER, border = 4 ) sizers = wx.BoxSizer(wx.VERTICAL) sizers.Add( self .title,proportion = , flag = wx.BOTTOM|wx.TOP|wx.ALIGN_CENTER,border = 10 ) sizers.Add(container_one,proportion = ,flag = wx.EXPAND|wx.LEFT|wx.RIGHT,border = 40 ) sizers.Add(container_two, proportion = , flag = wx.EXPAND | wx.LEFT | wx.RIGHT, border = 40 ) sizers.Add(container_four, proportion = , flag = wx.EXPAND | wx.LEFT | wx.RIGHT, border = 40 ) sizers.Add(container_three, proportion = , flag = wx.ALIGN_CENTER|wx.TOP, border = 10 ) panel.SetSizer(sizers) if __name__ = = "__main__" : app = wx.App() frame = MyFrame() frame.Show() app.MainLoop()

4. 写日记页面程序（MainPage.py）

1234567891011121314151617181920212223242526 from tkinter import * class MainPage( object ): def __init__( self , master = None ): self .root = master # 定义内部变量root self .root.geometry( '%dx%d' % ( 600 , 400 )) # 设置窗口大小 self .createPage() def createPage( self ): self .inputPage = InputFrame( self .root) # 创建不同Frame self .queryPage = QueryFrame( self .root) self .countPage = CountFrame( self .root) self .aboutPage = AboutFrame( self .root) self .inputPage.pack() # 默认显示数据录入界面 menubar = Menu( self .root) menubar.add_command(label = '写日记' , command = self .inputData) menubar.add_command(label = '看日记' , command = self .queryData) self .root[ 'menu' ] = menubar # 设置菜单栏 def inputData( self ): self .inputPage.pack() self .queryPage.pack_forget() self .countPage.pack_forget() self .aboutPage.pack_forget() def queryData( self ): self .inputPage.pack_forget() self .queryPage.pack() self .countPage.pack_forget() self .aboutPage.pack_forget()
