用python 实现activex网页控件首先，这个东东貌似只有windows上才能实现，所以，需要部署windows下的相关环境 1、需要安装python 2、安装python的win32com的lib，下载地址： http://sourceforge.net/projects/pywin32/files/ 3、安装本地的web容器，我用的apache的tomcat 4、编写例子： import uuid 阅读详情

最近在wxpython中嵌入Office Activex 可以用ActivexWarper来实现

不过py2exe打包的时候很麻烦，因为引用了mfc的dll，经常是RunTime Error

只好换成ActiveXCtrl

BaseViewer就是一个wxPanel

这个Office控件里面有很多的事件需要用到，下面是控件的makepy的导出片段

class _DEDOfficeEvents:
	'Event interface for Edraw Office Viewer Component'
	CLSID = CLSID_Sink = IID('{321F8EAC-5B6C-40FD-8B04-289FEF4C28A5}')
	coclass_clsid = IID('{7677E74E-5831-4C9E-A2DD-9B1EF9DF2DB4}')
	_public_methods_ = [] # For COM Server support
	_dispid_to_func_ = {
		       27 : "OnSlideSelectionChanged",
		       28 : "OnColorSchemeChanged",
		       14 : "OnDownloadFileComplete",
		       26 : "OnSlideShowNextSlide",
		        3 : "OnBeforeDocumentOpened",
		       17 : "OnSheetActivate",
		        5 : "OnBeforeDocumentClosed",
		       20 : "OnSheetChange",
		        8 : "OnWindowBeforeDoubleClick",
		        7 : "OnWindowBeforeRightClick",
		       16 : "OnIESecurityReminder",
		       23 : "OnSlideShowBegin",
		       13 : "OnBeforeDownloadFile",
		        4 : "OnDocumentOpened",
		       24 : "OnSlideShowEnd",
		       19 : "OnSheetCalculate",
		       18 : "OnSheetDeactivate",
		       12 : "OnWindowDeactivate",
		        1 : "OnNotifyCtrlReady",
		       25 : "OnSlideShowNextBuild",
		       10 : "OnDocumentBeforePrint",
		       22 : "OnPresentationNewSlide",
		        2 : "OnNewDocument",
		       29 : "OnSlideShowNextClick",
		        6 : "OnBeforeDocumentSaved",
		       11 : "OnWindowActivate",
		       21 : "OnWorkbookNewSheet",
		       15 : "OnUploadComplete",
		        9 : "OnWindowSelectionChange",
		}

	def __init__(self, oobj = None):
		if oobj is None:
			self._olecp = None
		else:
			import win32com.server.util
			from win32com.server.policy import EventHandlerPolicy
			cpc=oobj._oleobj_.QueryInterface(pythoncom.IID_IConnectionPointContainer)
			cp=cpc.FindConnectionPoint(self.CLSID_Sink)
			cookie=cp.Advise(win32com.server.util.wrap(self, usePolicy=EventHandlerPolicy))
			self._olecp,self._olecp_cookie = cp,cookie
	def __del__(self):
		try:
			self.close()
		except pythoncom.com_error:
			pass
	def close(self):
		if self._olecp is not None:
			cp,cookie,self._olecp,self._olecp_cookie = self._olecp,self._olecp_cookie,None,None
			cp.Unadvise(cookie)
	def _query_interface_(self, iid):
		import win32com.server.util
		if iid==self.CLSID_Sink: return win32com.server.util.wrap(self)

如果我们要监听OnBeforeDocuemtnOpened

下面是我的的窗口的代码，BaseViewer就是一个wxPanel,定义一个BeforeDocuemtnOpened

那么在文档打开前就会执行BeforeDocuemtnOpened方法，

ActievxCtrl初始化源代码里面有 self.AddEventSink(self) ，所以控件会在OfficeViewer里找对应的Event调用

class OfficeViewer(BaseViewer):

	def __init__(self,parent=None,filename='',dir=BaseViewer.EDITOR_DIR):
		BaseViewer.__init__(self,dir,parent)
		sizer = wx.BoxSizer(wx.VERTICAL)
		self.officeAtx=ActiveXCtrl(self,'EDOFFICE.EDOfficeCtrl.1',-1)

		sizer.Add(self.officeAtx, 1, wx.EXPAND)
		self.SetSizer(sizer)

		self.officeAtx.AddEventSink(self)
		self.officeAtx=self.officeAtx.ctrl

		self.temp=''
		self.filename=filename
		self.dir=dir


	def BeforeDocumentOpened(self):

		"""禁止打印命令"""
		MessageBox('Before Open')
		self.officeAtx.DisableFileCommand(0x00000200,True)
