I make a custom virtual keyboard which base on QWidget.

And it work properly on Windows/Ubuntu os.

But when i deploy it to my target develop board which base on ARM , it is not working. When i click an input field, the keyboard is displayed and disappears immediately. I check my keyboard log, it seems that the keyboard accept focus and then call commit function (from QPlatformInputContext).

I have set my view: view->setWindowFlags(Qt::Tool | Qt::FramelessWindowHint | Qt::WindowStaysOnTopHint | Qt::WindowDoesNotAcceptFocus);

If i change the export QT_QPA_PLATFORM=wayland to export QT_QPA_PLATFORM=linuxfb, the keyboard work nice as same as on desktop.

But for some reason, I can't modify it.

Any advice appreciated it, thx in advance.
