75 Panels are <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG> windows with the added feature of
76 depth. Panel functions allow the use of stacked windows
77 and ensure the proper portions of each window and the
78 curses <STRONG>stdscr</STRONG> window are hidden or displayed when panels
79 are added, moved, modified or removed. The set of cur-
80 rently visible panels is the stack of panels. The <STRONG>stdscr</STRONG>
81 window is beneath all panels, and is not considered part
84 A window is associated with every panel. The panel rou-
85 tines enable you to create, move, hide, and show panels,
86 as well as position a panel at any desired location in the

94 </PRE><H2><a name="h2-FUNCTIONS">FUNCTIONS</a></H2><PRE>
95 <STRONG>new_panel(win)</STRONG>
96 allocates a <STRONG>PANEL</STRONG> structure, associates it with
97 <STRONG>win</STRONG>, places the panel on the top of the stack
98 (causes it to be displayed above any other
99 panel) and returns a pointer to the new panel.
101 <STRONG>update_panels()</STRONG>
102 refreshes the virtual screen to reflect the rela-
103 tions between the panels in the stack, but does not
104 call doupdate() to refresh the physical screen.
105 Use this function and not <STRONG>wrefresh</STRONG> or <STRONG>wnoutrefresh</STRONG>.
106 <STRONG>update_panels</STRONG> may be called more than once before a
107 call to doupdate(), but doupdate() is the function
108 responsible for updating the physical screen.
110 <STRONG>del_panel(pan)</STRONG>
111 removes the given panel from the stack and deallo-
112 cates the <STRONG>PANEL</STRONG> structure (but not its associated
115 <STRONG>hide_panel(pan)</STRONG>
116 removes the given panel from the panel stack and
117 thus hides it from view. The <STRONG>PANEL</STRONG> structure is not
118 lost, merely removed from the stack.
120 <STRONG>panel_hidden(pan)</STRONG>
121 returns <STRONG>TRUE</STRONG> if the panel is in the panel stack,
122 <STRONG>FALSE</STRONG> if it is not. If the panel is a null
125 <STRONG>show_panel(pan)</STRONG>
126 makes a hidden panel visible by placing it on top
127 of the panels in the panel stack. See COMPATIBILITY
130 <STRONG>top_panel(pan)</STRONG>
131 puts the given visible panel on top of all panels
132 in the stack. See COMPATIBILITY below.
134 <STRONG>bottom_panel(pan)</STRONG>
135 puts panel at the bottom of all panels.
137 <STRONG>move_panel(pan,starty,startx)</STRONG>
138 moves the given panel window so that its upper-left
139 corner is at <STRONG>starty</STRONG>, <STRONG>startx</STRONG>. It does not change
140 the position of the panel in the stack. Be sure to
141 use this function, not <STRONG>mvwin()</STRONG>, to move a panel
144 <STRONG>replace_panel(pan,window)</STRONG>
145 replaces the current window of panel with <STRONG>window</STRONG>
146 (useful, for example if you want to resize a panel;
147 if you're using <STRONG>ncurses</STRONG>, you can call <STRONG>replace_panel</STRONG>
148 on the output of <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG>). It does not change
149 the position of the panel in the stack.
151 <STRONG>panel_above(pan)</STRONG>
152 returns a pointer to the panel above pan. If the
153 panel argument is <STRONG>(PANEL</STRONG> <STRONG>*)0</STRONG>, it returns a pointer
154 to the bottom panel in the stack.
156 <STRONG>panel_below(pan)</STRONG>
157 returns a pointer to the panel just below pan. If
158 the panel argument is <STRONG>(PANEL</STRONG> <STRONG>*)0</STRONG>, it returns a
159 pointer to the top panel in the stack.
161 <STRONG>set_panel_userptr(pan,ptr)</STRONG>
162 sets the panel's user pointer.
164 <STRONG>panel_userptr(pan)</STRONG>
165 returns the user pointer for a given panel.
167 <STRONG>panel_window(pan)</STRONG>
168 returns a pointer to the window of the given panel.
171 </PRE><H2><a name="h2-DIAGNOSTICS">DIAGNOSTICS</a></H2><PRE>
172 Each routine that returns a pointer returns <STRONG>NULL</STRONG> if an
173 error occurs. Each routine that returns an int value
174 returns <STRONG>OK</STRONG> if it executes successfully and <STRONG>ERR</STRONG> if not.
177 </PRE><H2><a name="h2-COMPATIBILITY">COMPATIBILITY</a></H2><PRE>
178 Reasonable care has been taken to ensure compatibility
179 with the native panel facility introduced in SVr3.2
180 (inspection of the SVr4 manual pages suggests the program-
181 ming interface is unchanged). The <STRONG>PANEL</STRONG> data structures
182 are merely similar. The programmer is cautioned not to
183 directly use <STRONG>PANEL</STRONG> fields.
185 The functions <STRONG>show_panel()</STRONG> and <STRONG>top_panel()</STRONG> are identical
186 in this implementation, and work equally well with dis-
187 played or hidden panels. In the native System V implemen-
188 tation, <STRONG>show_panel()</STRONG> is intended for making a hidden panel
189 visible (at the top of the stack) and <STRONG>top_panel()</STRONG> is
190 intended for making an already-visible panel move to the
191 top of the stack. You are cautioned to use the correct
192 function to ensure compatibility with native panel
