88 These functions perform useful drawing and attribute operations.

91 boxWindow
92 draw a box with on the window win. Like attrbox, this function
93 ORs attr with each character as it draws the box.
94 attrbox
96 draw a box with on the window win letting the caller define each
97 element of the box.
98 The parameters tlc, trc, blc, brc are used for the top-left, top-
100 right, bottom-left and bottom-right corners respectively. The
101 parameters horz and vert are used for the horizontal and vertical
102 sides of the box. Any of these parameters may be zero. In that
103 case, the function skips the corresponding element of the box.
104 The function ORs attr with each character as it draws the box.
106 drawObjBox
108 Draw a box around the given window win using the object's defined
109 line-drawing characters.
110 drawLine
112 draw a line on the given window.
113 The parameters starty, startx are the starting coordinates. The
115 parameters endy, endx are the ending coordinates. The function
116 writes the data in line to each coordinate in that range including
117 the start/end coordinates.
118 The function handles lines other than vertical or horizontal, but
120 normally it is used for that, e.g., with line set to ACS_HLINE or
121 ACS_VLINE.
122 drawShadow
124 draw a shadow on the right and bottom edges of a window.
125 writeBlanks
127 write a string of blanks, using writeChar. The parameters are
128 passed to writeChar as is. There is no corresponding write‐
129 BlanksAttrib function.
130 writeChar
132 writes out a char * string without adding attributes. The parame‐
133 ters are passed to writeCharAttrib as is.
134 writeCharAttrib
136 writes out a char * string with the given attributes added. The
137 string is written to the given window, using its relative screen
138 coordinates ypos and xpos.
139 Compare with writeChtypeAttrib, which writes a chtype * string.
141 The function ORs the attribute attr with each item from the
143 string. For instance, it may be A_BOLD. The align parameter con‐
144 trols whether it is written horizontally (HORIZONTAL) or verti‐
145 cally (VERTICAL).
146 Finally, only a subset of the string is written. The function
148 starts with the data from the start item of string, and ends
149 before the end item. If start is greater than, or equal to end,
150 no data is written.
151 writeChtype
153 writes out a chtype * string without adding attributes. The
154 parameters are passed to writeChtypeAttrib as is.
155 writeChtypeAttrib
157 writes out a chtype * string with the given attributes added. The
158 string is written to the given window, using its relative screen
159 coordinates ypos and xpos. You would normally construct the
160 string from a char * string using char2Chtype (3).
161 The function ORs the attribute attr with each item from the
163 string. For instance, it may be A_BOLD. The align parameter con‐
164 trols whether it is written horizontally (HORIZONTAL) or verti‐
165 cally (VERTICAL).
166 Finally, only a subset of the string is written. The function
168 starts with the data from the start item of string, and ends
169 before the end item. If start is greater than, or equal to end,
170 no data is written.
