Standard_EXPORT | Graphic2d_TransientManager (const Handle(Graphic2d_View)&aView) |

Standard_EXPORT Standard_Boolean | BeginDraw (const Handle(Aspect_WindowDriver)&aDriver, const Standard_Boolean ClearBefore=Standard_True) |
Begins any graphics in the view <aview> and Driver <adriver> with the current view attributes in a transient area. Restore the front buffer from the back before if <clearbefore> is TRUE. Warning: Returns TRUE if transient backing-store is enabled in the associated view. Returns FALSE ,if nothing works because something is wrong for the transient principle : Immediat mode is not implemented depending of the graphic library used. MBX,PIXMAP double buffering don't works depending of the graphic board and the visual of the window supporting the view. . | |
