.SH NAME
wxGLContext \- 
  Class to ease sharing of OpenGL data resources.
 
.SH DESCRIPTION

  


   wxGLContext is a class for sharing OpenGL data resources, such as display
   lists, with another
   wxGLCanvas
   .
  
  


   By sharing data resources, you can prevent code duplication, save memory, and
   ultimately help optimize your application.
  
  


   As an example, let's say you want to draw a ball on two different windows
   that is identical on each one, but the dimensions of one is slightly
   different than the other one. What you would do is create your display lists
   in the shared context, and then translate each ball on the individual
   canvas's context. This way the actual data for the ball is only created once
   (in the shared context), and you won't have to duplicate your development
   efforts on the second ball.
  
  


   Note that some wxGLContext features are extremely platform-specific - its
   best to check your native platform's glcanvas header (on windows
   include/wx/msw/glcanvas.h) to see what features your native platform
   provides.

.SS void wxGLContext (bool isRGBwxGLCanvas* winconst wxPalette& palette = wxNullPalette)

.SS void wxGLContext (bool isRGBwxGLCanvas* winconst wxPalette& palette = wxNullPaletteconst wxGLContext* other)

   
  
.SS const wxWindow* GetWindow ()

     


      Obtains the window that is associated with this context.
     
    
   
  
.SS void SetCurrent ()

     


      Sets this context as the current recipient of OpenGL calls. Each context
      contains an OpenGL device context that has been created during the
      creation of this window. So this call sets the current device context as
      the target device context for OpenGL operations.
     
    
   
  
.SS void SetColour (const char* colour)

     


      Sets the current colour for this context, using the wxWidgets colour
      database to find a named colour.
     
    
   
  
.SS void SwapBuffers ()

     


      Displays the previous OpenGL commands on the associated window.
