[Mono-winforms-list] Theming in MWF

Surely native theming is an option - Java has its SWING toolkit that
does native theming and more, and who would want a Win98 look of your
app on Mac OS X. If someone suggested why even use MWF - then the
answer would be because it's easy, and it uses one of the most
powerful IDE's to date - Visual Studio 2005. If we had "proper"
theming support then I would imagine more people would use MWF on
Linux (for example).

Myself, I took a look at the look of MWF on Linux, and was horrified
at how it contrasts with other applications. Personally, I would
prefer to have native look in MWF, but if that's not possible, then I
will have to (for my project) use MWF for windows, GTK for Linux and
maybe the native Cocoa calls in OS X.

I'm not suggesting that the current implementation is not feature-rich
or indeed, good enough to use, but unless wxWidgets (the native C++
library) becomes an integral part of Mono, I think it's up to the MWF
to make native widgets, or indeed, themable widgets. And no,
personally I will never use wxWidgets because it's a dependency - and
the aim of my app is to have as little dependencies as possible.
