There is no way at the moment. There used to be a "python binding" with 
lcd4linux-0.9, but for all the evaluator stuff, this doesn't make too 
much sense anymore.

Hmm... this should be possible. All you need is to provide an interface 
where python could send the data to, and lcd4linux collects them from. 
As a workaround you could simply save them into a file, and use 
lcd4linux's 'exec' plugin to read them.

In the near future there will be something like a "general file parsing 
plugin", which can read and parse any file, and read from fifo's, too. 
This will be a quite clean solution.

Correct, not at the moment. Some display drivers already provide 
reading/polling for keypresses, but there is no internal framework yet 
that handles these events. But this will change rather quickly....

Thanks!

Well, graphical displays are already supported! Think of the Image 
driver, the X11 driver, the T6963 driver....

At the moment there are no widgets which really use the graphical power 
of such displays. But things like "Image widgets", or "Graphs" are planned.
