macOS上的Qt应用程序:如何找到当前活动的屏幕？

#include <QApplication>
#include <QScreen>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    // 获取主屏幕
    QScreen *primaryScreen = QGuiApplication::primaryScreen();

    // 获取鼠标当前所在位置的屏幕
    QScreen *currentScreen = QGuiApplication::screenAt(QCursor::pos());

    // 输出屏幕相关信息
    qDebug() << "Primary Screen: " << primaryScreen->name();
    qDebug() << "Current Screen: " << currentScreen->name();

    return app.exec();
}
