 The TX11GL is X11 implementation of TVirtualGLImp class.

TX11GLManager() : fPimpl(new TX11GLImpl)

~TX11GLManager()

Int_t InitGLWindow(Window_t winID, Bool_t isOffScreen)

Try to find correct visual

Int_t CreateGLContext(Int_t winInd)

context creation requires Display * and XVisualInfo (was saved for such winInd)

Bool_t MakeCurrent(Int_t devInd)

Make gl context current

void Flush(Int_t devInd, Int_t, Int_t)

swaps buffers for window or copy pixmap

Bool_t CreateGLPixmap(Int_t winInd, Int_t x, Int_t y, UInt_t w, UInt_t h, Int_t prevInd)

creates new x11 pixmap, gl pixmap, gl context

Int_t OpenGLPixmap(Int_t winInd, Int_t x, Int_t y, UInt_t w, UInt_t h)

create new X11 pixmap and GLX pixmap and gl context for
off-screen drawing - new device

void ResizeGLPixmap(Int_t pixInd, Int_t x, Int_t y, UInt_t w, UInt_t h)

void SelectGLPixmap(Int_t pixInd)

selects off-screen device to make it
accessible by gVirtualX

void MarkForDirectCopy(Int_t pixInd, Bool_t dir)

void DeletePaintDevice(Int_t devInd)

Int_t GetVirtualXInd(Int_t glPix)

void ExtractViewport(Int_t pixId, Int_t *viewport)

void DrawViewer(TVirtualViewer3D *vv)

TObject* Select(TVirtualViewer3D *vv, Int_t x, Int_t y)
