How to implement a custom keyboard(old cellphone like)?

[A Former User]

Hello guys,

I'm using Qt5.8 on a embedded linux device and I need to implement a custom keyboard. The behaviour is the same of that old cellphones keypads where each time you press a digit button repeatedly it becomes a different letter. For example:

Button 1 alternates between 1, Q, Z, ., q, z
Button 2 alternates between 2, A, B, C, a, b, c
.
.
.

Keyboard driver is located on /dev/input/event0 though Qt only recognize digits from 0...9.

Maybe it's an old question but I don't know a good term to describe this behaviour.
Does Qt have something ready for this?

Hi,

You might find something in the QtVirtualKeyboard module although you are likely going to have to handle the T9 style input yourself since your keyboard only sends number.
