详细描述

The QWinThumbnailToolBar class allows manipulating the thumbnail toolbar of a window.

应用程序可以将工具栏嵌入窗口缩略图，会展示工具栏当鼠标悬停任务栏图标时。缩略工具栏可以提供窗口命令的快速访问，无需要求用户还原或激活窗口。

The following example code illustrates how to use the functions in the QWinThumbnailToolBar and QWinThumbnailToolButton 类以实现缩略图工具栏：

    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);

[slot] void QWinThumbnailToolBar:: clear ()

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.

该函数在 Qt 5.4 引入。

另请参阅 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.

该函数在 Qt 5.4 引入。
