bar

raw OCR

Draws a two-dimensional bar.

Defined in header <graphics.h>

Syntax

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

Portability

Remarks

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 barSd 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.

Example

#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>

int main(void)
{
   /* request autodetection */
   int gdriver = DETECT, gmode, errorcode;
   int midx, midy, i;

   /* initialize graphics and local variables */
   initgraphl&gdriver, &gmode, "");

   /* read result of initialization */
   errorcode = graphresult ();
   if (errorcode != grOk) {   /* an error occurred  */
      printf("Graphics error: %s\n", grapherrormsg (errorcode));
      printf("Press any key to halt:");
      getchO ;
      exit(l);               /* terminate with an error code  */
   }
   midx = getmaxx() / 2;
   midy = getmaxyO  / 2;

   /* loop through the fill patterns */
   for (i=SOLID_FILL; i<USER_FILL; i++) {
      /* set the fill style */
      setfillstyle(i, getmaxcolorO );

      /* draw the bar */
      bar(midx-50, midy-50, midx+50, midy+50);
   getchO ;
}
/* clean up */
closegraphO ;
return 0;
