I don't see a question, what is it that you are posting for?

[Ankit.k]

Is there any function which detects external key press and is there any function through which we can have alphabet selection, for instance on key press the alphabet selection ranges from a-z and on release the last letter is selected

most keypresses, even special buttons, go via a QKeyEvent that you can get on your QWidget that has focus. If you use qml, there are similar ways. Just search for "focus".
The thing you describe can be build by you, using Qt. The building blocks are there. Check the documentation :)
