\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}.

/*! 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.
