> What is the difference between a ligature and a contextual form?
According to: http://en.wikipedia.org/wiki/Arabic_alphabet#Ligatures,
there is only one compulsory ligature (having two forms, see later), and
that's the one I showed in a previous mail.
The contextual forms means that in general, each character has four
different presentation forms. These are the unicode points in the
arabic_table in src/Encoding.cpp. The unicode points are located in the
"Arabic Presentation Forms-B" unicode table.
Thanks, I understand now.
(i hope you can see the figures)
Nope. It is strange because in your previous message I had nice
pictures. But I this is the information from the wikipedia page, I
read it now.
Yes, I finished and sent the mail on mobile GMail, and I started
worrying about the figures.
:) Actually, my plan is to find an API somewhere that does the work
for me. I want some library that tells me what to do, without having
to care about the language I am using. Do you think this is too much
to ask?
I thought you wanted this: "I want to have some feeling of how this
works. " Now, you tell me you want to remain dumb ;).
No, Qt provides you with all the tools. However, we should use the
library correctly.
Is there a widget in Qt that is able to edit arabic text, for example?
If I find one, I will look up the sources and try to understand what
they do.
All Qt Widgets where you can enter text can edit arabic. The magic is
behind QPainter::drawText.
