Re: TashkeelHandler: A QT C++ Class

["Mete Kural" <metek at touchtonecorp dot com>]

Wa aleykum as-salaam Abdalla,

Mashallah TashkeelHandler sounds very powerful. I would be delighted to see a version of QT GUI that provides the user the option to view the Quran text with varying levels of marks. I lack the C++ skills to do this myself though. If you add this feature by any chance in a future GUI version that would be neat.

Thank you,
Mete
