詳細描述

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

應用程序可以將工具欄嵌入窗口縮略圖，會展示工具欄當鼠標懸停任務欄圖標時。縮略工具欄可以提供窗口命令的快速訪問，無需要求用戶還原或激活窗口。

The following example code illustrates how to use the functions in the QWinThumbnailToolBar and QWinThumbnailToolButton 類以實現縮略圖工具欄：

    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);

Returns the list of buttons in the thumbnail toolbar.

另請參閱 setButtons ().

[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.

該函數在 Qt 5.4 引入。
