How to share texture object with mutil qglwidget

[feiz]

Hello,
I am developing a application,i need some qglwidgets share a volume 3d texture.I know

QGLWidget::QGLWidget(QWidget * parent = 0, const QGLWidget * shareWidget = 0, Qt::WindowFlags f = 0)

QGLWidget::QGLWidget(QWidget * parent = 0, const QGLWidget * shareWidget = 0, Qt::WindowFlags f = 0)

To copy to clipboard, switch view to plain text mode 

can share texture between two qglwidget(Qglwidget share with shareWidget).Is
tere a way to share texture with multi qglwidget?

Thanks,
