hide_panel, show_panel, panel_hidden -- visibility of panels
Z-order for curses windows (libpanel, -lpanel)
Panels are initially created visible. The function hide_panel() can be
used to hide a panel. The panel is removed from the deck.
A panel can be made visible again with a call to show_panel(). The panel
is returned to the top of the deck.
The current visibility status of a panel can be queried with
The show_panel() function will return an error if the panel is already
visible. Use top_panel(3) to change z-order of an already visible panel.
This is the behaviour specified by the original AT&T System V UNIX panel
In the ncurses implementation of the panel library show_panel() and
top_panel() are identical and handle both visible and hidden panels.
This may be a source of bugs in programs tested only against ncurses.
The panel_hidden() function returns TRUE or FALSE. It will return ERR if
passed a null pointer.
Other functions will return one of the following values:
OK The function completed successfully.
ERR An error occurred in the function.
