    \brief A push button with a text label.

    \image button.png

    The push button is perhaps the most commonly used widget in any graphical
    user interface. Pushing (or clicking) a button commands the computer to
    perform some action or answer a question. Common examples of buttons are
    OK, Apply, Cancel, Close, Yes, No, and Help buttons.

    \qml
    Button {
        text: "Button"
    }
    \endqml

    Button is similar to the QPushButton widget.

    You can create a custom appearance for a Button by
    assigning a \l {ButtonStyle}.

    id: button

    /*! This property holds whether the push button is the default button.
        Default buttons decide what happens when the user presses enter in a
        dialog without giving a button explicit focus. \note This property only
        changes the appearance of the button. The expected behavior needs to be
        implemented by the user.

        The default value is \c false.
