Hi Zachary Scheuren
Thanks a lot for your answer .The reason I have Email PYQT is that I use
its widgets and I forgot to say that I use Qtextedit.And for more detail I
can say that I found that pyarabic library before and as you said I can
remove marks with its strip_tashkeel(text) function ,But if you take a look
at below example I think you will find what I want to do.And I can refer
you to http://tanzil.net here if you search for "السماء" it will find and
highlight "ٱلسَّمَآءِ" I want to know if its possible in python?I use
sqlite database and I could find the results like this but I can not
highlight them.
Example :
search for :" السماء "
but I want to show Quranuthmani and find :" ٱلسَّمَآءِ" in it and
highlight them.
I can find them with no problem cause of using sqlite database table with
different Quran text But the problem is highlighting them cause of using
and " السماء " ," ٱلسَّمَآءِ" are not the same so I can not highlight them.
Please accept my apologizes for asking my question before your permission .
