Qt keypressevent detects key press as hexa not ascii

[Lavanya]

Hi everyone,
here i wrote a small application on serialport using Qserialport class where i done all the appliocation but struct with one final step. our customer wants to send a hexadecimal data not asciicharachters but keypress event will detect keyboard keys as only ascii charachters.
So i want to know is there any procedure so that on GUI if i choose hex data then after if i press keys from keyboard ot should sense keys as hexa data also non hexa charachter(say like g to z) should be given a as non hexa charachter you entered.
Is there any way to achive this.
Thnaks & Regards

You should rephrase this as it is hard to understand what you mean.
If you want to send numbers as hex strings (a key is nothing else as a number) then use https://doc.qt.io/qt-5/qstring.html#number

sorry for making it difficult post.
My doubt is very simple i want to design the application same as Pcomm terminal where we have sending hexadecimal data facility.

@Lavanya
Nobody here knows what "same as Pcomm terminal" might be, nor how it behaves, nor what you want behaviour-wise from it.

@jsulm stated what to call to convert a number to a hexadecimal string.
