</PRE><H2><a name="h2-FUNCTIONS">FUNCTIONS</a></H2><PRE>
- <STRONG>new_panel(win)</STRONG>
- allocates a <STRONG>PANEL</STRONG> structure, associates it with <STRONG>win</STRONG>, 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.
-
- <STRONG>update_panels</STRONG>
- refreshes the <EM>virtual</EM> <EM>screen</EM> to reflect the relations between
- the panels in the stack, but does not call <STRONG>doupdate</STRONG> to refresh
- the <EM>physical</EM> <EM>screen</EM>. Use this function and not <STRONG>wrefresh</STRONG> or
- <STRONG>wnoutrefresh</STRONG>. <STRONG>update_panels</STRONG> may be called more than once before
- a call to <STRONG>doupdate</STRONG>, but <STRONG>doupdate</STRONG> is the function responsible for
- updating the <EM>physical</EM> <EM>screen</EM>.
-
- <STRONG>del_panel(pan)</STRONG>
- removes the given panel from the stack and deallocates the
- <STRONG>PANEL</STRONG> structure (but not its associated window).
-
- <STRONG>hide_panel(pan)</STRONG>
- removes the given panel from the panel stack and thus hides it
- from view. The <STRONG>PANEL</STRONG> structure is not lost, merely removed from
- the stack.
-
- <STRONG>panel_hidden(pan)</STRONG>
- returns <STRONG>TRUE</STRONG> if the panel is in the panel stack, <STRONG>FALSE</STRONG> if it is
- not. If the panel is a null pointer, return <STRONG>ERR</STRONG>.
-
- <STRONG>show_panel(pan)</STRONG>
- makes a hidden panel visible by placing it on top of the panels
- in the panel stack. See COMPATIBILITY below.
-
- <STRONG>top_panel(pan)</STRONG>
- puts the given visible panel on top of all panels in the stack.
- See COMPATIBILITY below.
-
- <STRONG>bottom_panel(pan)</STRONG>
- puts panel at the bottom of all panels.
-
- <STRONG>move_panel(pan,starty,startx)</STRONG>
- moves the given panel window so that its upper-left corner is at
- <STRONG>starty</STRONG>, <STRONG>startx</STRONG>. It does not change the position of the panel in
- the stack. Be sure to use this function, not <STRONG>mvwin</STRONG>, to move a
- panel window.
-
- <STRONG>replace_panel(pan,window)</STRONG>
- replaces the current window of panel with <STRONG>window</STRONG> (useful, for
- example if you want to resize a panel; if you're using <STRONG>ncurses</STRONG>,
- you can call <STRONG>replace_panel</STRONG> on the output of <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG>). It
- does not change the position of the panel in the stack.
-
- <STRONG>panel_above(pan)</STRONG>
- returns a pointer to the panel above pan. If the panel argument
- is <STRONG>(PANEL</STRONG> <STRONG>*)0</STRONG>, it returns a pointer to the bottom panel in the
- stack.
-
- <STRONG>panel_below(pan)</STRONG>
- returns a pointer to the panel just below pan. If the panel
- argument is <STRONG>(PANEL</STRONG> <STRONG>*)0</STRONG>, it returns a pointer to the top panel in
- the stack.
-
- <STRONG>set_panel_userptr(pan,ptr)</STRONG>
- sets the panel's user pointer.
-
- <STRONG>panel_userptr(pan)</STRONG>
- returns the user pointer for a given panel.
-
- <STRONG>panel_window(pan)</STRONG>
- returns a pointer to the window of the given panel.

+ (1990).
+
+ According to Tucker, the SystemV panel library was first released

+
+ Several developers have improved each of these; they are no longer
