\section{\class{wxBusyCursor}}\label{wxbusycursor}

This class makes it easy to tell your user that the program is temporarily busy.
Just create a wxBusyCursor object on the stack, and within the current scope,
the hourglass will be shown.

For example:

\begin{verbatim}
  wxBusyCursor wait;

  for (int i = 0; i < 100000; i++)
    DoACalculation();
\end{verbatim}

It works by calling \helpref{wxBeginBusyCursor}{wxbeginbusycursor} in the constructor,
and \helpref{wxEndBusyCursor}{wxendbusycursor} in the destructor.
