Detailed Description

Applications can embed a toolbar in the thumbnail of a window, which is shown when hovering over its taskbar icon. A thumbnail toolbar may provide quick access to the commands of a window without requiring the user to restore or activate the window.

Media player thumbnail toolbar

The following example code illustrates how to use the functions in the QWinThumbnailToolBar and QWinThumbnailToolButton class to implement a thumbnail toolbar:

    QWinThumbnailToolBar *thumbbar = new QWinThumbnailToolBar(widget);
    thumbbar->setWindow(widget->windowHandle());

    QWinThumbnailToolButton *settings = new QWinThumbnailToolButton(thumbbar);
    settings->setToolTip("Settings");
    settings->setIcon(":/settings.png");
    settings->setDismissOnClick(true);
    connect(settings, SIGNAL(clicked()), settingsPage, SLOT(show()));

    QWinThumbnailToolButton *playPause = new QWinThumbnailToolButton(thumbbar);
    playPause->setToolTip("Play/Pause");
    playPause->setIcon(":/play.png");
    connect(playPause, SIGNAL(clicked()), mediaPlayer, SLOT(play()));

    thumbbar->addButton(settings);
    thumbbar->addButton(playPause);

Removes all buttons from the thumbnail toolbar.

[signal] void QWinThumbnailToolBar::iconicLivePreviewPixmapRequested()

This signal is emitted when the operating system requests a new iconic live preview pixmap, typically when the user ALT-tabs to the application.

This function was introduced in Qt 5.4.

See also iconicLivePreviewPixmap.

[signal] void QWinThumbnailToolBar::iconicThumbnailPixmapRequested()

This signal is emitted when the operating system requests a new iconic thumbnail pixmap, typically when the thumbnail is shown.

This function was introduced in Qt 5.4.
