original code:

parent=self, pos=wx.Point(368, 216), size=wx.Size(224, 320),
style=wx.html.HW_SCROLLBAR_AUTO)

The backend now is Explorer (probably windows' default - i'm on windows 7)

I tried the following argument options::
backend="WebViewBackendWebKit"
backend=WebViewBackendWebKit
backend=wx.html2.WebViewBackendWebKit

But none works.
I search the whole python directory, and the word "WebViewBackendWebKit"
doesn't exist anywhere.
According to the documentation, there should be a "backend" argument,
and it should be a string. The error below expects type
'wxWebViewBackend' - which i don't know how to produce.

The change to using a string to specify the backend happened just a few weeks ago, before that it was using an enum named... you guessed it: wxWebViewBackend. The enum values were

  >>> for d in dir(wx.html2):
  ... if 'backend' in d.lower():
  ... print d
  ...
  WEB_VIEW_BACKEND_DEFAULT
  WEB_VIEW_BACKEND_IE
  WEB_VIEW_BACKEND_WEBKIT
  >>>

However the only backend available for Windows is the IE backend. The architecture is designed to allow others, but none have been written and added to wxWidgets yet. I think I read something about a webkit plugin for Windows being worked on, but so far it hasn't been incorporated into wxWidgets.

So I was too optimistic :slight_smile:
I’ll either wait or try wxwebconnect then…
Thank you

CEF (Embedded Chrome )could be a nice option:

http://code.google.com/p/chromiumembedded/

There are Python bindings already, though not sure they'd help here:

oh -- they might, they have a sample of embedding CEF in wxPython!
