Visibility of Frames
====================

   A window frame may be "visible", "invisible", or "iconified".  If it
is visible, you can see its contents.  If it is iconified, the frame's
contents do not appear on the screen, but an icon does.  If the frame
is invisible, it doesn't show on the screen, not even as an icon.

   Visibility is meaningless for terminal frames, since only the
selected one is actually displayed in any case.

 - Command: make-frame-visible &optional frame
     This function makes frame FRAME visible.  If you omit FRAME, it
     makes the selected frame visible.

 - Command: make-frame-invisible &optional frame
     This function makes frame FRAME invisible.  If you omit FRAME, it
     makes the selected frame invisible.

 - Command: iconify-frame &optional frame
     This function iconifies frame FRAME.  If you omit FRAME, it
     iconifies the selected frame.

 - Function: frame-visible-p frame
     This returns the visibility status of frame FRAME.  The value is
     `t' if FRAME is visible, `nil' if it is invisible, and `icon' if
     it is iconified.

   The visibility status of a frame is also available as a frame
parameter.  You can read or change it as such.  Note: Window Frame
Parameters.

   The user can iconify and deiconify frames with the window manager.
This happens below the level at which Emacs can exert any control, but
Emacs does provide events that you can use to keep track of such
changes.  Note: Misc Events.
