/* Palm OS Event handler for the window

 * This function *must* be located outside of the wxTopLevelWindow class because
 * the Palm OS API expects a standalone C function as a callback.  You cannot
 * pass a pointer to a member function of a C++ class as a callback because the
 * prototypes don't match.  (A member function has a hidden "this" pointer as
 * its first parameter).
 *
 * This event handler uses a global pointer to the current wxFrame to process
 * the events generated by the Palm OS form API.  I know this is ugly, but right
 * now I can't think of any other way to deal with this problem.  If someone
 * finds a better solution, please let me know.  My email address is
