This is to use Qt's user interface classes, so that Qt Designer can be used to create a .ui file defining the interface (just like TW's own "native" windows and dialogs). Because all the Qt GUI code is already present in the application, this would add very little "bloat"; we'd just need a thin layer of "glue" code connecting the UI loader and widgets to scripts, rather than pulling in an entire multi-megabyte Web browser engine in order to present a dialog box.

Cool - I'd also begun a patch for this, so I'll compare the two and see what comes out of the mixture! :)

That's because you're using a full Qt installation that includes the QtWebkit module (libQtWebkit.so or something like that). It won't work for people using my Mac or Windows builds, where this is not included. We could add it, of course, but the footprint would be BIG.

Thanks, I'll check that in too.
