    1. Add this line to your project's .pr file.
    include(path/to/widgetkeyboard/src/WidgetKeyboard.pri)
    2. Include the WidgetKeyboard and use it like a normal Qt widget.

    As simple as that.

    Hello!

    I'm studying that application, and have one question about it. Why keyboard doesn't show if I remove Layouts (gridLayout_5)? I thought It's only for good look of application. I tried to find some connection in code but didn't find anything.

    thanks in advance
    best regards
    Tomasz
