// FrameWindow.C

// X does not echo back the window-map events (it probably should when
// override_redirect is off).  Unfortunately this means you have to use
// this subclass if you want a "normal" fltk window, it will force a
// Frame to be created and destroy it upon hide.

// Warning: modal() does not work!  Don't turn it on as it screws up the
// interface with the window borders.  You can use set_non_modal() to
// disable the iconize box but the window manager must be written to
// not be modal.
