/*
 *  Window Events
 *  -------------
 *  This program demonstrates the use of three window call-back
 *  functions: setresize, setredraw and setclose.
 *
 *  If a window is resized, the resize callback happens first,
 *  then the redraw callback. If the used closes the window using
 *  the button in the top-left of the titlebar, the close function
 *  is called.
 *
 *  Note that if you supply a close function the window will not
 *  automatically vanish any more. You must explicitly hide the
 *  window using the hide function. The hide function works with
 *  buttons, checkboxes etc as well as windows.
