The reason that Win32Lib gets attention is that people are actually using it
to do useful things.
The main problem that I'm having with Llama is with GTK+ graphics. GTK+
requires that I either (1) define a canvas-like control that can be drawn
on, or use xlib to do the rendering.
At one point, I had wrapped a good chunk of xlib, but the code seems to have
disappeared. [Pete - do you still have the copy I sent you?] I don't really
want to have to fool around with xlib - it adds another level of complexity
that I'd rather do without.
The other option is to add a 'canvas' control into Llama. That would be yet
another divergence between Win32Lib and Llama. This isn't necessarily a bad
thing. For one thing, I could make graphics rendered to the canvas
persistant - you wouldn't have to redraw them each time the window is
damaged.
I haven't decided between the two. If someone has already wrapped xlib, I'd
probably go with the first option.

Not even a consideration.
One major goal in making Llama more open was to get the load of me in terms
of development. For example, Greg Harris helped a lot in porting classes
from Win32Lib to the posted version of Llama.
I have a Win32 and a GTK version of Llama up and running based on the same
core library. The GTK version has enough controls to be useful - PushButton,
CheckBox, Radio, Menu, and so on. I haven't posted it because it's coded
around the Win32 GTK DLLs, and hasn't been tested under Linux recently. I
suspect that th
The Win32 version, in contrast, only has a Window and PushButton class
working, although it shouldn't be too hard to convert the classes from prior
versions of Llama to add support for new controls quickly.
I'll try to get the Win32 version onto my web page in the next couple of
days.
