.SH FUNCTIONS
.TP
-\fBnew_panel(win)\fR
+.B new_panel(win)
allocates a \fBPANEL\fR structure, associates it with
\fBwin\fR, places the panel on the top of the stack (causes it
to be displayed above any other panel) and returns a
pointer to the new panel.
.TP
-\fBvoid update_panels()\fR
+.B update_panels()
refreshes the virtual screen to reflect the relations between the
panels in the stack, but does not call doupdate() to refresh the
-physical screen. Use this function and not wrefresh or wnoutrefresh.
-update_panels() may be called more than once before a call to
+physical screen.
+Use this function and not \fBwrefresh\fP or \fBwnoutrefresh\fP.
+.B update_panels
+may be called more than once before a call to
doupdate(), but doupdate() is the function responsible for updating
the physical screen.
.TP
-\fBdel_panel(pan)\fR
+.B del_panel(pan)
removes the given panel from the stack and deallocates the
\fBPANEL\fR structure (but not its associated window).
.TP
-\fBhide_panel(pan)\fR
+.B hide_panel(pan)
removes the given panel from the panel stack and thus hides it from
view. The \fBPANEL\fR structure is not lost, merely removed from the stack.
.TP
-\fBshow_panel(pan)\fR
+.B panel_hidden(pan)
+returns TRUE if the panel is in the panel stack,
+FALSE if it is not.
+If the panel is a null pointer, return ERR.
+.TP
+.B show_panel(pan)
makes a hidden panel visible by placing it on top of the panels in the
panel stack. See COMPATIBILITY below.
.TP
-\fBtop_panel(pan)\fR
+.B top_panel(pan)
puts the given visible panel on top of all panels in the stack. See
COMPATIBILITY below.
.TP
-\fBbottom_panel(pan)\fR
+.B bottom_panel(pan)
puts panel at the bottom of all panels.
.TP
-\fBmove_panel(pan,starty,startx)\fR
+.B move_panel(pan,starty,startx)
moves the given panel window so that its upper-left corner is at
\fBstarty\fR, \fBstartx\fR. It does not change the position of the
panel in the stack. Be sure to use this function, not \fBmvwin()\fR,
to move a panel window.
.TP
-\fBreplace_panel(pan,window)\fR
+.B replace_panel(pan,window)
replaces the current window of panel with \fBwindow\fR (useful, for
example if you want to resize a panel; if you're using \fBncurses\fR,
you can call \fBreplace_panel\fR on the output of \fBwresize\fR(3X)).
It does not change the position of the panel in the stack.
.TP
-\fBpanel_above(pan)\fR
+.B panel_above(pan)
returns a pointer to the panel above pan. If the panel argument is
\fB(PANEL *)0\fR, it returns a pointer to the bottom panel in the stack.
.TP
-\fBpanel_below(pan)\fR
+.B panel_below(pan)
returns a pointer to the panel just below pan. If the panel argument
is \fB(PANEL *)0\fR, it returns a pointer to the top panel in the stack.
.TP
-\fBset_panel_userptr(pan,ptr)\fR
+.B set_panel_userptr(pan,ptr)
sets the panel's user pointer.
.TP
-\fBpanel_userptr(pan)\fR
+.B panel_userptr(pan)
returns the user pointer for a given panel.
.TP
-\fBpanel_window(pan)\fR
+.B panel_window(pan)
returns a pointer to the window of the given panel.
.SH DIAGNOSTICS
Each routine that returns a pointer returns \fBNULL\fR if an error
