Python doesn't have const values. You could define them as variables, and you 
can also provide handwritten code using %VariableCode if you need to fiddle 
with them. To be honest I can't remember the details as PyQt no longer makes 
use of this. Try...

static int MAX_LEN;
%VariableCode
	Replace this when we've worked out what to do.
%End

...and look at the generated code.

Not supported, just comment out.

Remove the "virtual".

>     static void delay( struct timeval ); //Error

I assume it's complaining about "struct timeval". You need to wrap this as 
well - or use %MappedType to use something like a tuple instead.
