I have a python application which need a gui HTML editor, I know FCKeditor is nice, so how to embed the FCKeditor in a python desktop app?
In order of difficulty:
If you just need to support Windows, you can embed IE in wx - see the docs and demos.
wxWebKit is looking a bit more mature, but it's still in development.
You could just use the web-browser using webbrowser.open(url). Things will be very crude, and interaction will be a pain.
A fourth option - you could try out pyjamas for your whole GUI, then run it all in a web-browser.
