第十二章作业

实例01  使用wx.StaticText输出Python之禅

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='优雅胜于丑陋',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='即便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，但不假思索就动手做还不如不做',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()

 

 

 

实例02  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TexCtrl类",size=(400, 300))

        panel = wx.Panel(self)

        self.title = wx.StaticText(panel,label="请输入用户命和密码",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()

 

 

实例03  为登录界面添加“确认”和“取消”按键

import wx

class MyFrame(wx.Frame):

    def __init__(self,parent,id):

        wx.Frame.__init__(self,parent,id, title="创建TexCtrl类",size=(400, 300))

        panel = wx.Panel(self)

        self.title = wx.StaticText(panel,label="请输入用户命和密码",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_cancel = 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()

 

实例04  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, '用户登录', size=(400,300))
panel = wx.Panel(self)

self.bt_confirm = wx.Button(panel, label='确定')
self.bt_cancel = wx.Button(panel, label='取消')
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)
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)
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()

 

 

 

 

 

实例05  使用事件判断用户登录

import wx

class MyFrame(wx.Frame):
def __init__(self, parent, id):
wx.Frame.__init__(self, parent, id, '用户登录', size=(400,300))
panel = wx.Panel(self)

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.OnclickSubmit)
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)
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)
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，执行方法 """
message = ""
username = self.text_user.GetValue()
password = self.text_password.GetValue()
if username == "" or password == "":
message = '用户名或密码不能为空'
elif username == 'mr' and password =='mrsoft':
message = '登录成功'
else:
message = '用户名和密码不匹配'
wx.MessageBox(message)

def OnclickCancel(self,event):
""" 单击取消按键，执行方法 """
self.text_user.SetValue("")
self.text_password.SetValue("")

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