Thanks Peter,
I will start with the font increase, decrease part then. Is important.
My eyes are not so young now. Will try building some small widget with a
Tex class using text area and two buttons. It shouldn't be so hard.
Cheers,

Hi,
I would like to create some GUI that would be essentially a text
area field plus some buttons. The idea is to support
- Font size increasing/decreasing.
- Syntaxt highlighting for markup languages.
The hardest part is the syntax highlighting itself, because you need (ideally
non-strict) parser and highlighter for each language. There are several
languages that use PetitParser for both.
Then you basically build up the text with `Text`, (`Text` class supports things
like specifying color, emphasis, etc.).
And then you can just show the text in a RubTextArea.
You can even use Spec' TextModel; I used TextModel and PetitParser based
highlightning for coloring my DSL, but I never got around to finishing it.
I believe Johan's Live State Machine editor does something similar.
Also look at Pillar support (I saw mails floating around that it was updated or
something).

I gave a glimpse to the RubTextAreaExamples yesterday, but if anyone
knows a more complete example to start with, that would be really
helpful.
