\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.

To switch wxGLCanvas support on under Windows, edit setup.h and set
{\tt wxUSE\_GLCANVAS} to $1$. You may also need to have to add
{\tt opengl32.lib} to the list of libraries your program is linked with. On
Unix, pass {\tt --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.
