| |
| 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}. |
