1. Add this line to your project's .pr file.

2. Include the WidgetKeyboard and use it like a normal Qt widget.

As simple as that. ;)

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
