In the TextExample, it has an example to render source code.
I am wonder what is the best way to implement color syntaxing when use that
to render source code.
I am thinking I can scan the content to look for key words and create a
number of TextFlow objects for text before the keyword, the keyword itself
and text after the keyword. And then set the font of each TextFlow
accordingly.
Is there a better approach than this? My concern is performance, since I
need to create a lot of small TextFlow objects.
Thank for any feedback.
