| |
| \brief Manages Windows taskbar buttons. |
| |
| \since QtWinExtras 1.0 |
| |
| The TaskbarButton type enables you to set an overlay icon and to display |
| a progress indicator on a taskbar button. An overlay icon indicates change |
| in the state of the application. A progress indicator shows how time-consuming |
| tasks are progressing. |
| |
| \section3 Example |
| |
| The following example illustrates how to use TaskbarButton in QML: |
| |
| \snippet code/taskbar.qml taskbar_qml |
