I want to make a simple editor using wxPython. Complete code is already available in wxPython tutorial page (http://wiki.wxpython.org/WxHowtoSmallEditor). However, in addition I want to add "print" menu which will print the contents of editor (i.e., whatever written in editor). I will appreciate if someone please show me.

Thanks,
Akand

Here you are as you wanted buddy

Thanks for response. Line 114 shows attribute error:


self.log.WriteText('GetAllPages: %d\n' % data.GetAllPages())

AttributeError

'MainWindow' object has no attribute 'log'

You should be fine with this
This will print to a fie if you got no printer in place

Thank you very much and I appreciate your co-operation. Can the OnPrint function be modified such that I can print from the frame directly assuming I have printer in place? My objective is not to have an editor, rather using this "Print" idea somewhere else.

At least you show some appreciation by upvoting or something before asking for some more my friend.
