[Ironpython-users] GUI Toolkits

Tue Dec 2 17:18:14 CET 2014

Hi, Andrew,

I just had another (maybe weird) idea:

Maybe your users could use HTML Forms to define the UI, and you use an embedded WebbrowserControl to render the UI, and use the DOM tree to read and write the values. Create a slim python function for this which accepts an HTML form fragment and a dictionary with the values, and you should be done. :-)

Best regards
