bar

Syntax

#include <graphics.h>
void bar(int left, int top, int right, int bottom);

Description

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.

Return Value

None.
