| \brief Push-button that can be clicked to perform a command or answer a question. |
| |
| \image qtquickcontrols2-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. |
| |

| Button { |
| text: "Ok" |
| onClicked: model.submit() |
