详细描述
The QWinThumbnailToolBar class allows manipulating the thumbnail toolbar of a window.
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.
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);
属性

成员函数
QWinThumbnailToolBar::QWinThumbnailToolBar(QObject *parent = Q_NULLPTR)
Constructs a QWinThumbnailToolBar with the specified parent.
If parent is an instance of QWindow, it is automatically assigned as the thumbnail toolbar's window.
QWinThumbnailToolBar::~QWinThumbnailToolBar()
Destroys and clears the QWinThumbnailToolBar.
void QWinThumbnailToolBar::addButton(QWinThumbnailToolButton *button)
Adds a button to the thumbnail toolbar.
Note: The number of buttons is limited to 7.
QList<QWinThumbnailToolButton *> QWinThumbnailToolBar::buttons() const
Returns the list of buttons in the thumbnail toolbar.
参见 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.
This function was introduced in Qt 5.4.
[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.
void QWinThumbnailToolBar::removeButton(QWinThumbnailToolButton *button)
Removes the button from the thumbnail toolbar.
void QWinThumbnailToolBar::setButtons(const QList<QWinThumbnailToolButton *> &buttons)
Sets the list of buttons in the thumbnail toolbar.
Note: Any existing buttons are replaced.
参见 buttons().
