编写环境：
1、ActivePython-2.7.2.5-win32-x86
2、wxPython2.8-win32-unicode-2.8.12.1-py27
3、wxFormBuilder_v3.3.3-beta
以下代码是演示怎样利用IEHtmlWindow载入网页，并实现打印预览和打印的的功能：
#coding:utf-8
import wx
from wx.lib import iewin
class MyFrame ( wx.Frame ):
def __init__( self, parent ):
wx.Frame.__init__ ( self, parent, id = wx.ID_ANY, title = wx.EmptyString, pos = wx.DefaultPosition, size = wx.Size( 674,421 ), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL )
self.SetSizeHintsSz( wx.DefaultSize, wx.DefaultSize )
self.menu = wx.MenuBar( 0 )
self.menu1 = wx.Menu()
self.LoadPage = wx.MenuItem( self.menu1, wx.ID_ANY, u"打开文件", wx.EmptyString, wx.ITEM_NORMAL )
self.menu1.AppendItem( self.LoadPage )
self.PrintPreview = wx.MenuItem( self.menu1, wx.ID_ANY, u"打印预览", wx.EmptyString, wx.ITEM_NORMAL )
self.menu1.AppendItem( self.PrintPreview )
self.Print = wx.MenuItem( self.menu1, wx.ID_ANY, u"打印", wx.EmptyString, wx.ITEM_NORMAL )
self.menu1.AppendItem( self.Print )
self.menu.Append( self.menu1, u"文件" )
self.SetMenuBar( self.menu )
bSizer = wx.BoxSizer( wx.VERTICAL )
self.ie = iewin.IEHtmlWindow(self)
self.ie.AddEventSink(self)
bSizer.Add( self.ie, 1, wx.EXPAND, 5 )
self.Centre( wx.BOTH )
# Connect Events
self.Bind( wx.EVT_MENU, self.LoadPageOnMenuSelection, id = self.LoadPage.GetId() )
self.Bind( wx.EVT_MENU, self.PrintPreviewOnMenuSelection, id = self.PrintPreview.GetId() )
self.Bind( wx.EVT_MENU, self.PrintOnMenuSelection, id = self.Print.GetId() )
def __del__( self ):
pass
def DocumentComplete(self,this,pDisp,URL):
print 'Done'
# Virtual event handlers, overide them in your derived class
def LoadPageOnMenuSelection( self, event ):
#self.ie.Navigate("http://baidu.com/") # your URL here
#self.ie.LoadUrl('http://www.baidu.com')
#self.ie.LoadStream(page)
#self.ie.LoadString(page)
loadstring = u'''
<html>
<body>
<p align="center"><font face="华文琥珀" size="7" color="#CC3300">这是一个简单的测试……</font></p>

self.ie.LoadString(loadstring)
#import StringIO
#self. ie.LoadStream( StringIO.StringIO( page.decode("utf8") ) )
#file = open('index2.htm')
#self. ie.LoadStream(file)
#file.close()
event.Skip()
def PrintPreviewOnMenuSelection( self, event ):
self.ie.PrintPreview()
event.Skip()
def PrintOnMenuSelection( self, event ):
self.ie.Print(True)
event.Skip()
app = wx.PySimpleApp()
frm = MyFrame(None)
frm.Maximize()
frm.Show()
app.MainLoop() |
