如何在Windows 7任务栏中显示进度(使用Qt)？

你可以使用这个QWinTaskbarProgress类。要使用这个类，你需要添加win32:QT += winextras你的.pro文件。

下面是一个示例代码，演示如何QProgressBar在Windows任务栏中显示a的值（从此示例中得到启发）：

#ifdef _WIN32    //The _WIN32 macro is automatically generated when compiling for Windows
    #include <QWinTaskbarProgress>
    #include <QWinTaskbarButton>
#endif
QProgressBar *progressBar = new QProgressBar;
progressBar->show();
#ifdef _WIN32
    QWinTaskbarButton *windowsTaskbarButton new QWinTaskbarButton;    //Create the taskbar button which will show the progress
    windowsTaskbarButtonsetWindow(progressBarwindowHandle//Associate the taskbar button to the progress bar,assuming that the progress bar is its own window
    QWinTaskbarProgress *windowsTaskbarProgress = windowsTaskbarButtonprogress;
    windowsTaskbarProgress;
    QObject::connect(loadingWindow, &QProgressBar:valueChanged[windowsTaskbarProgress](int value{
        windowsTaskbarProgresssetValue(value;   //Change the value of the progress in the taskbar when the value of the progress bar changes
    };
#endif
