31 \ingroup TEve
32 Eve representation of TGLViewer.
33 
34 The gl-viewer is owned by this class and is deleted in destructor.
35 
36 The frame is not deleted, it is expected that the gl-viewer implementation
37 will delete that. TGLSAViewer and TGEmbeddedViewer both do so.
38 This could be an optional argument to SetGLViewer. A frame could be
39 passed as well.
40 
41 When stand-alone viewer is requested, it will come up with menu-hiding
42 enabled by default. If you dislike this, add the following line to rootrc
43 file (or set corresponding gEnv entry in application initialization):
44 ~~~ {.cpp}
