So you basically provide just the model and some hints/constraints and let the GUI toolkit automatically generate native look&feel widgets to present and edit the model. This means the GUI toolkit needs to understand and implement the guidelines on each platform (how many GUI developers actually follow these guidelines 100%?)

If you provide constraints that are conflicting between GUI platforms, you have to either relax the constraints or provide different widgets for each platform.

All nice theoretically, but not done yet?

This is one of many reasons why I don't believe any of these cross-platform toolkits will ever be good enough to make truly native-like UIs – The bottom line is that tab views are different between Mac OS and other OSes, they have much more padding round them on Mac OS. This means that any layout you create involving them will never work on both platforms.

See e.g. http://wiki.wxwidgets.org/WxWidgets_Compared_To_Other_Toolkits

So I don't understand how come the look and feel is different then...

Using native GUI libraries is necessary, but not sufficient for
achieving the same look and feel. :)

Other elements are layout and spacing,

drag & drop,

writing style and fonts

etc, etc.

Thirdly, the textlogs have different fonts. Again, the wxHaskell one
looks non-standard.

Honestly, I can't tell. They are both very similar, sans fonts. Also, the
font could be explained by the fact that these screen shots are taken on
different computers (different OS versions, different settings).

There is a default set of fonts

http://developer.apple.decenturl.com/human-interface-guidelines-text

The "mini system font" is the typography of choice for text boxes, but
it looks the "application font" is acceptable as well.

In any case, I think these differences are minor.

I don't. :)

More importantly, I'm not sure that a different cross-platform
toolkit would do a better job.

True, that. It's just that this doesn't mean that wxWidgets does a very
good job.
