GPIO IRQ keyboard ，QT5.9

[hongwu]

I working with Qt5.9, there is no QWS supported , and I can't find more articals about how can I use QPA plugins to driver my custom hardware keyboard, any advise ?
My keyboard is GPIO IRQ. I can detect the key in my QT application by scanning the GPIO. But I want make a keyboard driver and send keyboard event that any app window can receive it like QWS_KEYBOARD have done in QT4
I have no experience about driver developping on linux platform，just read some artical about QWS_KEYBOARD plugins development，but I‘m working with QT5.9，so I’m stucked

Hi and welcome to devnet,

AFAIR, you should check QInputMethod.

KDAB has several articles on the subject.
