void arrow_standalone()
// ----------------------------------------------------------------------
auto mf = new TGMainFrame(gClient->GetRoot(), 800, 400,
mf->SetWindowName("Arrow Foo");
// ----------------------------------------------------------------------
auto evf = new TGCompositeFrame(mf, 400, 400);
mf->AddFrame(evf, new TGLayoutHints(kLHintsNormal |
auto ev = new TGLEmbeddedViewer(evf);
auto eve_v = new TEveViewer("YourViewer");
eve_v->SetGLViewer(ev, ev->GetFrame());
// ----------------------------------------------------------------------
// To create embedded canvas ... no menus on top.
// TRootEmbeddedCanvas* ec =
// new TRootEmbeddedCanvas("EmbeddedCanvas", mf, 400, 400);
// mf->AddFrame(ec, new TGLayoutHints(kLHintsNormal |
// kLHintsExpandX | kLHintsExpandY));
// --------------------------------
// This one is tricky - must be after embedded canvas but before std canvas!
// --------------------------------
// To create full canvas with menus.
auto c = new TCanvas("Foo", "Bar", 400, 400);
// ----------------------------------------------------------------------

// Populate the viewer ... here we just call the arrow.C.
