wxGLContext example in a wxGLCanvas

[akkumar]

I was going thru' the constructor of wxGLCanvas and came across this third overloaded form .


void wxGLCanvas(wxWindow* parent, wxGLContext* sharedContext = NULL, wxWindowID id = -1, const wxPoint& pos, const wxSize& size, long style=0, const wxString& name="GLCanvas", int* attribList = 0, const wxPalette& palette = wxNullPalette)


What does sharedcontext indicate ? Can anyone point me to a practical example where this could be useful.

sharedcontext is used to share resources (display lists, etc.) with another context (I.E. another canvas for now).

I'll also add some docs for wxGLContext to head.
