python 学习

前几天无聊，在网上看别人写了一个wxpython例子，写了一个东西非常的好玩，感觉python开发软件也不错，开发效率比较高，于是自己也学了点wxpython的前面一点内容，自己写了个例子玩玩：

import os

import sys

import wx

ID_OPEN = 101

ID_EXIT = 110

ID_SAVE = 111

ID_BUTTON = 112



class MainWindow(wx.Frame):

""" We simply derive a new class of Frame. """

def __init__(self, parent, id, title):

wx.Frame.__init__(self, parent, id, title, size=(500,100))

self.control = wx.TextCtrl(self, 1, style=wx.TE_MULTILINE)

self.CreateStatusBar()

filemenu = wx.Menu()

filemenu.Append(ID_OPEN,"打开文件","open file")

filemenu.AppendSeparator()

filemenu.Append(ID_SAVE,"保存文件"," save file")

filemenu.AppendSeparator()

filemenu.Append(ID_EXIT,"退出","exit")

menuBar = wx.MenuBar()

menuBar.Append(filemenu,"文件")

self.SetMenuBar(menuBar)

wx.EVT_MENU(self,ID_OPEN,self.open)

wx.EVT_MENU(self,ID_EXIT,self.exit)

wx.EVT_MENU(self,ID_SAVE,self.save)

self.sizer2 = wx.BoxSizer(wx.HORIZONTAL)

self.buttons = []



# for i in range(0,6):

# self.buttons.append(wx.Button(self,ID_BUTTON+i,"Button &"+'i'))

# self.sizer2.Add(self.buttons[i],1,wx.EXPAND)

self.sizer = wx.BoxSizer(wx.VERTICAL)

self.sizer.Add(self.control,1,wx.EXPAND)

self.sizer.Add(self.sizer2,0,wx.EXPAND)

self.SetSizer(self.sizer)

self.SetAutoLayout(1)

self.sizer.Fit(self)



self.Show(True)



def exit(self,e):

'''用户退出窗口'''

self.Close(True)



def open(self,e):

'''打开文件 '''

self.dirname = ''

dlg = wx.FileDialog(self,"chose a file",self.dirname,"","*.*",wx.OPEN)



if dlg.ShowModal() == wx.ID_OK:

self.filename = dlg.GetFilename()

self.dirname = dlg.GetDirectory()

f = open(os.path.join(self.dirname,self.filename),'r')

self.control.SetValue(f.read())

f.close()

dlg.Destroy()



def save(self,e):

'''保存文件'''

try:

f = open(os.path.join(self.dirname,self.filename),'w')

except AttributeError:

print '文件不存在'

sys.exit(0)



content = self.control.GetValue()

try:

f.write(content)

except UnboundLocalError:

print '文件不存在'

sys.exit(0)

finally:

f.close()





app = wx.PySimpleApp()

frame=MainWindow(None,-1, 'Small editor')

app.MainLoop()

直接运行就可以生成一个窗口，有打开和关闭的功能，其他的功能没有完善，有兴趣的朋友可以学习下，然后到老王python 里和大家一起分享你的成果吧！
