QMovie::updated()怎么触发QMovie::currentImage

[qq_30100389]

#######mainwindow.h

class MainWindow:public QMainWindow
{
Q_OBJECT
public:
QImage image;

public slots:
void getima()
{
image = QMovie::currentImage();
}
}
######mainwindow.cpp

QMovie movie = new QMovie("gifpath");

QObeject::connect(&movie,SIGNAL(updated(const Rect)),&image,SLOT(currentImage()));

######error:
cannot call member function "QImage QMovie::currentImage() const " without object；

求大神解答疑惑！万分感谢！！！

追加：我的意图是想让QMvoie的信号：updated()发生时，将当前帧捕获出来；

[void_main_void]

信号槽，需要参数相同才能被触发吧。。

[qq_30100389]

void QMovie::updated(const QRect & rect) signal
This signal is emitted when the rect rect in the current frame has been updated. You can call currentImage() or currentPixmap() to get a copy of the updated frame.

currentImage 的返回值是QImage呀？哎？难道真的是connect(movie,SIGNAL(updated()),movie,SLOT(currentImage()));

currentImage() 为QMovie的方法，你为什么要用到QImage中呢！
