Hi Jeremy, Thanks for reply. My target with creating HUD display is playing osgMovie imagestreamed texture in it. If I can achive this operation by osgWidget I glad to use this API. And if it is possible, which osgWidget sample should I glimps? Because I have never tried osgWidget before except looking built-in samples in osg.
