    \brief Keyboard layout.

    This type is the root element of the keyboard layout.
    Use this element to build a new keyboard layout.

    Example:

    \code
    import QtQuick 2.0
    import QtQuick.Layouts 1.0
    import QtQuick.VirtualKeyboard 2.1

    // file: layouts/en_GB/main.qml

    KeyboardLayout {
        KeyboardRow {
            Key {
                key: Qt.Key_Q
                text: "q"
            }
            Key {
                key: Qt.Key_W
                text: "w"
            }
            Key {
                key: Qt.Key_E
                text: "e"
            }
            Key {
                key: Qt.Key_R
                text: "r"
            }
            Key {
                key: Qt.Key_T
                text: "t"
            }
            Key {
                key: Qt.Key_Y
                text: "y"
            }
        }
    }

        layout changes.
