\brief Push-button that can be clicked to perform a command or answer a question.
\image qtquickcontrols-button.gif
Button presents a push-button control that can be pushed or clicked by
the user. Buttons are normally used to perform an action, or to answer
a question. Typical buttons are \e OK, \e Apply, \e Cancel, \e Close,
\e Yes, \e No, and \e Help.
Button inherits its API from AbstractButton. For instance, you can set
\l {AbstractButton::text}{text}, display an \l {Icons in Qt Quick Controls}{icon},
and react to \l {AbstractButton::clicked}{clicks} using the AbstractButton API.
A button emits the signal \l {AbstractButton::}{clicked()} when it is activated by the user.
Connect to this signal to perform the button's action. Buttons also
provide the signals \l {AbstractButton::}{canceled()}, \l {AbstractButton::}{doubleClicked()}, \l {AbstractButton::}{pressed()},
\l {AbstractButton::}{released()} and \l {AbstractButton::}{pressAndHold()} for long presses.
See the snippet below on how to connect to the button's signals.
\code
RowLayout {
Button {
text: "Ok"
onClicked: model.submit()
}
Button {
text: "Cancel"
onClicked: model.revert()
}
}
