Detailed Description

The QWinTaskbarButton class represents the Windows taskbar button for a window.

The QWinTaskbarButton class enables you to set overlay icons on a taskbar button, and provides access to its progress indicator.

An overlay icon indicates change in the state of an application, whereas a progress indicator shows how time-consuming tasks are progressing.

Taskbar Button

The following example code illustrates how to use the QWinTaskbarButton and QWinTaskbarProgress classes to adjust the look of the taskbar button:

    QWinTaskbarButton *button = new QWinTaskbarButton(widget);
    button->setWindow(widget->windowHandle());
    button->setOverlayIcon(QIcon(":/loading.png"));

    QWinTaskbarProgress *progress = button->progress();
    progress->setVisible(true);
    progress->setValue(50);
