\section{\class{wxGLCanvas}}\label{wxglcanvas}

wxGLCanvas is a class for displaying OpenGL graphics. There are
wrappers for OpenGL on Windows, and GTK+ and Motif.

To use this class, create a wxGLCanvas window, call \helpref{wxGLCanvas::SetCurrent}{wxglcanvassetcurrent} 
to direct normal OpenGL commands to the window, and then call \helpref{wxGLCanvas::SwapBuffers}{wxglcanvasswapbuffers} 
to show the OpenGL buffer on the window.

Please note that despite deriving from wxScrolledWindow, scrolling is not enabled for this class under
Windows.

To switch wxGLCanvas support on under Windows, edit setup.h and set wxUSE\_GLCANVAS to 1. On Unix,
pass --with-opengl to configure to compile using OpenGL or Mesa.

Constructor.

\membersection{wxGLCanvas::SetCurrent}\label{wxglcanvassetcurrent}

\func{void}{SetCurrent}{\void}

Sets this canvas as the current recipient of OpenGL calls.

\membersection{wxGLCanvas::SetColour}\label{wxglcanvassetcolour}

\func{void}{SetColour}{\param{const char*}{ colour}}

Sets the current colour for this window, using the wxWindows colour database to find a named colour.

\membersection{wxGLCanvas::SwapBuffers}\label{wxglcanvasswapbuffers}

\func{void}{SwapBuffers}{\void}

Displays the previous OpenGL commands on the window.
