Writing System in QFontDialog?

[ashukla]

I know nothing about Hindi fonts, but I suggested the demo for you to see how to properly apply font changes. You're particularly interested in TextEdit::textFamily(), TextEdit::textSize() etc. and TextEdit::mergeFormatOnWordOrSelection().

Here my means is not only Hindi Fonts but also writingSystem of QFontDialog. How to set the WritingSystem of QFontDialog. Because whenever I select from its list it viewed and cliked ok. But Again when I opened the dialog it any writing system appeared; which is by default.
