[QScintilla] Custom Lexer based on QscilexerCPP

[Steve Lamperti]

Hi,

I'm trying to build a custom lexer that is very closely based on the 
QSciLexerCPP class.  I started by thinking that I could just make a 
descendent of that class, and override methods in it to add my desired 
behaviors/keywords/etc.  But when I tried to do this, I quickly realized 
that the desired methods that I wanted to override were not virtual.  
(For example, I wanted to add a new style, and tried to override 
DefaultColor to give it a default.)

The syntax is really very close to QSciLexerCPP with just a few 
changes.  If someone could let me know what the recommended method to do 
this would be, I would appreciate it.  (One option that occurs to me, is 
just to copy the entire code of the QSciLeverCpp object, and perhaps 
this would be OK, but if I am missing something, I would appreciate 
hearing about it.)

Thanks,

-Steve L
