| + | ====Syntax of bar ==== | ||
| + | <code c> | ||
| + | #include <graphics.h> | ||
| + | void bar(int left, int top, int right, int bottom); | ||
| + | </code> | ||
| + | |||
| + | |||
| + | ==== Description of bar ==== | ||
| + | <code c> | ||
| + | bar draws a filled-in, rectangular, two-dimensional bar. The bar is | ||
| + | filled using the current fill pattern and fill color. bar does not | ||
| + | outline the bar; to draw an outlined two-dimensional bar, use bar3d with | ||
| + | depth equal to 0. | ||
| + | The upper left and lower right corners of the rectangle are given by | ||
| + | (left, top) and (right, bottom), respectively. The coordinates refer to | ||
| + | pixels. | ||
