wxGLContext example in a wxGLCanvas

Post by akkumar » Sat Sep 18, 2004 5:48 am

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).

For a more specific explanation -

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