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?
To embed FCKeditor (or maybe better the current CKeditor?), you basically need to embed a full-fledged browser (with Javascript) -- I believe wxPython may currently be the best bet for that, as I hear it has wxIE for Windows and wxWebKitCtrl for the Mac (I don't know if old summer-of-code ideas about making something suitable for Linux ever panned out, though).  Most "HTML viewer" widgets, in most GUIs, don't support Javascript, and that's a must for (F?)CKeditor.
