-<H2>DESCRIPTION</H2><PRE>
- Panels are <STRONG><A HREF="ncurses.3x.html">curses(3X)</A></STRONG> windows with the added feature of
- depth. Panel functions allow the use of stacked windows
- and ensure the proper portions of each window and the
- curses <STRONG>stdscr</STRONG> window are hidden or displayed when panels
- are added, moved, modified or removed. The set of cur-
- rently visible panels is the stack of panels. The <STRONG>stdscr</STRONG>
- window is beneath all panels, and is not considered part
- of the stack.
-
- A window is associated with every panel. The panel rou-
- tines enable you to create, move, hides, and show panels,
- as well as position a panel at any desired location in the
- stack.
-
- Panel routines are a functional layer added to <STRONG><A HREF="ncurses.3x.html">curses(3X)</A></STRONG>,
- make only high-level curses calls, and work anywhere ter-
- minfo curses does.
-
-
-</PRE>
-<H2>FUNCTIONS</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>void</STRONG> <STRONG>update_panels()</STRONG>
- refreshes the virtual screen to reflect the rela-
- tions between the panels in the stack, but does not
- update_panels() may be called more than once before
- a call to doupdate(), but doupdate() is the func-
- tion responsible for updating the physical screen.
-
- <STRONG>del_panel(pan)</STRONG>
- removes the given panel from the stack and deallo-
- cates 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>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.
- returns the user pointer for a given panel.
-
- <STRONG>panel_window(pan)</STRONG>
- returns a pointer to the window of the given panel.
-
-
-</PRE>
-<H2>DIAGNOSTICS</H2><PRE>
- Each routine that returns a pointer returns <STRONG>NULL</STRONG> if an
- error occurs. Each routine that returns an int value
- returns <STRONG>OK</STRONG> if it executes successfully and <STRONG>ERR</STRONG> if not.
-
-
-</PRE>
-<H2>COMPATIBILITY</H2><PRE>
- Reasonable care has been taken to ensure compatibility
- with the native panel facility introduced in SVr3.2
- (inspection of the SVr4 manual pages suggests the program-
- ming interface is unchanged). The <STRONG>PANEL</STRONG> data structures
- are merely similar. The programmer is cautioned not to
- directly use <STRONG>PANEL</STRONG> fields.
-
- The functions <STRONG>show_panel()</STRONG> and <STRONG>top_panel()</STRONG> are identical
- in this implementation, and work equally well with dis-
- played or hidden panels. In the native System V implemen-
- tation, <STRONG>show_panel()</STRONG> is intended for making a hidden panel
- visible (at the top of the stack) and <STRONG>top_panel()</STRONG> is
- intended for making an already-visible panel move to the
- top of the stack. You are cautioned to use the correct
- function to ensure compatibility with native panel
- libraries.

-<H2>NOTE</H2><PRE>
- In your library list, libpanel.a should be before libn-
- curses.a; that is, you want to say `-lpanel -lncurses',
- not the other way around (which would give you a link
- error using GNU <STRONG><A HREF="ld.1.html">ld(1)</A></STRONG> and some other linkers).
