实验 一  项目名称:      使用wx.StaticText输出Python之禅

# -*- coding:utf-8 -*-
import wx
class MyFrame(wx.Frame):
  def __init__(self,parent,id):
    wx.Frame.__init__(self,parent,id,title="创建StaticText类",
              pos=(100,100),size=(600,400))

    panel = wx.Panel(self)
    title = wx.StaticText(panel,label='Python之禅_Tim Peters',pos=(100,20))
    font = wx.Font(16,wx.DEFAULT,wx.FONTSTYLE_NORMAL,wx.NORMAL)
    title.SetFont(font)
    wx.StaticText(panel,label='优美胜于丑陋',pos=(50,50))
    wx.StaticText(panel,label='明了胜于晦涩',pos=(50,70))
    wx.StaticText(panel,label='简洁胜于复杂',pos=(50,90))
    wx.StaticText(panel,label='复杂胜于凌乱',pos=(50,110))
    wx.StaticText(panel,label='扁平胜于嵌套',pos=(50,130))
    wx.StaticText(panel,label='间隔胜于紧凑',pos=(50,150))
    wx.StaticText(panel,label='可读性很重要',pos=(50,170))
    wx.StaticText(panel,label='即使假借特例的实用性之名,也不可违背这些规        则',pos=(50,190))
    wx.StaticText(panel,label='不要包容所有错误,除非你也确定需要这样做',pos=(50,210))
    wx.StaticText(panel,label='当存在多种可能,不要尝试去猜测',pos=(50,230))
    wx.StaticText(panel,label='而是尽量找一种,最好是唯一一种明显的解决方案',pos=(50,250))
    wx.StaticText(panel,label='虽然这并不容易,因为你不是Python之父',pos=(50,270))
    wx.StaticText(panel,label='做也许好过不做,但不假思索就动手还不如不做',pos=  (50,290))
    wx.StaticText(panel,label='如果你无法向人描述你的方案,那肯定不是一个好方案;反之亦然',pos=(50,310))
    wx.StaticText(panel,label='命名空间是一种绝妙的理念,我们应当多加利用',pos=(50,330))

if __name__ == '__main__':
  app = wx.App()
  frame = MyFrame(parent=None,id=-1)
  frame.Show()
  app.MainLoop()

 

 

 

 

实验 二  项目名称:      使用wx.TextCtrl实现登录界面

import wx
class MyFrame(wx.Frame):
  def __init__(self,parent,id):
    wx.Frame.__init__(self,parent,id,title="创建TextCtrl类",size=(400,300))
    panel=wx.Panel(self)
    self.title = wx.StaticText(panel ,label="请输入用户名和密码",pos=(140,20))
    self.label_user = wx.StaticText(panel,label="用户名:",pos=(50,50))
    self.text_user = wx.TextCtrl(panel,pos=(100,50),size=(235,25),style=wx.TE_LEFT)
    self.label_pwd = wx.StaticText(panel,pos=(50,90),label="密 码:")
    self.text_password = wx.TextCtrl(panel,pos=(100,90),size=(235,25),style=wx.TE_PASSWORD)

if __name__ == '__main__':
  app = wx.App()
  frame = MyFrame(parent=None,id=-1)
  frame.Show()
  app.MainLoop()

 

 

 

实验 三  项目名称:      为登录界面添加“确认”和“取消”按钮

import wx
class MyFrame(wx.Frame):
  def __init__(self,parent,id):
    wx.Frame.__init__(self,parent,id,title="创建TextCtrl类",size=(400,300))
    panel=wx.Panel(self)
    self.title = wx.StaticText(panel ,label="请输入用户名和密码",pos=(140,20))
    self.label_user = wx.StaticText(panel,label="用户名:",pos=(50,50))
    self.text_user = wx.TextCtrl(panel,pos=(100,50),size=(235,25),style=wx.TE_LEFT)
    self.label_pwd = wx.StaticText(panel,pos=(50,90),label="密 码:")
    self.text_password = wx.TextCtrl(panel,pos=(100,90),size=(235,25),style=wx.TE_PASSWORD)
    self.bt_confirm = wx.Button(panel,label='确定',pos=(105,130))
    self.bt_confirm = wx.Button(panel,label='取消',pos=(195,130))
if __name__ == '__main__':
  app = wx.App()
  frame = MyFrame(parent=None,id=-1)
  frame.Show()
  app.MainLoop()

 

 

 

实验 四  项目名称:      使用BoxSizer设置登录界面布局

import wx
class MyFrame(wx.Frame):
  def __init__(self,parent,id):
    wx.Frame.__init__(self,parent,id,title="用户登录",size=(400,300))
    #创建面板
    panel=wx.Panel(self)
    #创建“确定”和“取消”按钮,并绑定事件
    self.bt_confirm = wx.Button(panel,label='确定')
    self.bt_cancel = wx.Button(panel,label='取消')
    #创建文本,左对齐
    self.title = wx.StaticText(panel ,label="请输入用户名和密码")
    self.label_user = wx.StaticText(panel,label="用户名:")
    self.text_user = wx.TextCtrl(panel,style=wx.TE_LEFT)
    self.label_pwd = wx.StaticText(panel,label="密 码:")
    self.text_password = wx.TextCtrl(panel,style=wx.TE_PASSWORD)

    #添加容器,容器中控件横向排列
    hsizer_user = wx.BoxSizer(wx.HORIZONTAL)
    hsizer_user.Add(self.label_user,proportion=0,flag=wx.ALL,border=5)
    hsizer_user.Add(self.text_user,proportion=1,flag=wx.ALL,border=5)
    hsizer_pwd = wx.BoxSizer(wx.HORIZONTAL)
    hsizer_pwd.Add(self.label_pwd,proportion=0,flag=wx.ALL,border=5)
    hsizer_pwd.Add(self.text_password,proportion=1,flag=wx.ALL,border=5)
    hsizer_button = wx.BoxSizer(wx.HORIZONTAL)
    hsizer_button.Add(self.bt_confirm,proportion=0,flag=wx.ALIGN_CENTER,border=5)
    hsizer_button.Add(self.bt_cancel,proportion=0,flag=wx.ALIGN_CENTER,border=5)
    #添加容器,容器中的控件纵向排列
    vsizer_all = wx.BoxSizer(wx.VERTICAL)
    vsizer_all.Add(self.title,proportion=0,flag=wx.BOTTOM | wx.TOP | wx.ALIGN_CENTER,border=15)
    vsizer_all.Add(hsizer_user,proportion=0,flag=wx.EXPAND | wx.LEFT |wx.RIGHT,border=45)
    vsizer_all.Add(hsizer_pwd,proportion=0,flag=wx.EXPAND | wx.LEFT |wx.RIGHT,border=45)
    vsizer_all.Add(hsizer_button,proportion=0,flag=wx.ALIGN_CENTER | wx.TOP,border=15)
    panel.SetSizer(vsizer_all)

if __name__ == '__main__':
  app = wx.App()
  frame = MyFrame(parent=None,id=-1)
  frame.Show()
  app.MainLoop()

 

 实验 五  项目名称:      使用事件判断用户登录

# -*- coding:utf-8 -*-
import wx
class MyFrame(wx.Frame):
  def __init__(self,parent,id):
    wx.Frame.__init__(self,parent,id,title="用户登录",size=(400,300))
    #创建面板
    panel=wx.Panel(self)
    #创建“确定”和“取消”按钮,并绑定事件
    self.bt_confirm = wx.Button(panel,label='确定')
    self.bt_confirm.Bind(wx.EVT_BUTTON,self.OnclickSubmit)
    self.bt_cancel = wx.Button(panel,label='取消')
    self.bt_cancel.Bind(wx.EVT_BUTTON,self.OnclickCancel)
    #创建文本,左对齐
    self.title = wx.StaticText(panel ,label="请输入用户名和密码")
    self.label_user = wx.StaticText(panel,label="用户名:")
    self.text_user = wx.TextCtrl(panel,style=wx.TE_LEFT)
    self.label_pwd = wx.StaticText(panel,label="密 码:")
    self.text_password = wx.TextCtrl(panel,style=wx.TE_PASSWORD)
    #添加容器,容器中控件横向排列
    hsizer_user = wx.BoxSizer(wx.HORIZONTAL)
    hsizer_user.Add(self.label_user,proportion=0,flag=wx.ALL,border=5)
    hsizer_user.Add(self.text_user,proportion=1,flag=wx.ALL,border=5)
    hsizer_pwd = wx.BoxSizer(wx.HORIZONTAL)
    hsizer_pwd.Add(self.label_pwd,proportion=0,flag=wx.ALL,border=5)
    hsizer_pwd.Add(self.text_password,proportion=1,flag=wx.ALL,border=5)
    hsizer_button = wx.BoxSizer(wx.HORIZONTAL)
    hsizer_button.Add(self.bt_confirm,proportion=0,flag=wx.ALIGN_CENTER,border=5)
    hsizer_button.Add(self.bt_cancel,proportion=0,flag=wx.ALIGN_CENTER,border=5)
    #添加容器,容器中的控件纵向排列
    vsizer_all = wx.BoxSizer(wx.VERTICAL)
    vsizer_all.Add(self.title,proportion=0,flag=wx.BOTTOM | wx.TOP | wx.ALIGN_CENTER,border=15)
    vsizer_all.Add(hsizer_user,proportion=0,flag=wx.EXPAND | wx.LEFT |wx.RIGHT,border=45)
    vsizer_all.Add(hsizer_pwd,proportion=0,flag=wx.EXPAND | wx.LEFT |wx.RIGHT,border=45)
    vsizer_all.Add(hsizer_button,proportion=0,flag=wx.ALIGN_CENTER | wx.TOP,border=15)
    panel.SetSizer(vsizer_all)

  def OnclickSubmit(self,event):
    '''单击确定按钮,执行方案'''
    message = ""
    username = self.text_user.GetValue()      #获取输入的用户名
    password = self.text_password.GetValue()        #获取输入的密码
    if username == "" or password == "":          #判断用户名或密码是否为空
      message = '用户名或密码不能为空'
    elif username == 'mr' and password == 'mrsoft':   #用户名和密码正确
      message = '登陆成功'
    else:
      message = '用户名和密码不匹配' #用户名或密码错误
    wx.MessageBox(message)


  def OnclickCancel(self,event):
    '''单击取消按钮,执行方案'''
    self.text_user.SetValue("") #清空输入的用户名
    self.text_password.SetValue("") #清空输入的密码


if __name__ == '__main__':
  app = wx.App()
  frame = MyFrame(parent=None, id=-1)
  frame.Show()
  app.MainLoop()
