GpiDrawSegment (1.2)
Function Group  Overview                          Up Next Previous
────────────────────────────────────────────────────────────────────────────
 
#define INCL_GPISEGMENTS
 
BOOL GpiDrawSegment(hps, idSegment)
HPS hps;           /* presentation-space handle     */
LONG idSegment;    /* identifier of segment to draw */
 
The GpiDrawSegment function draws the specified segment. The function draws
the segments using the current draw controls (except correlation control),
as set by the GpiSetDrawControl function. The function does not affect
drawing modes or open segments.
 
GpiDrawSegment cannot be used in an area, path, or element bracket.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
hps        Identifies the presentation space.
 
idSegment  Identifies the segment to draw. This parameter must be greater
           than zero.
 
Return Value
 
The return value is GPI_OK if the function is successful or GPI_ERROR if an
error occurred.
 
Errors
 
Use the WinGetLastError function to retrieve the error value, which may be
one of the following:
 
     PMERR_AREA_INCOMPLETE
     PMERR_IMAGE_INCOMPLETE
     PMERR_INV_HPS
     PMERR_INV_MICROPS_FUNCTION
     PMERR_INV_SEG_NAME
     PMERR_PATH_INCOMPLETE
     PMERR_PS_BUSY
     PMERR_SEG_NOT_FOUND
     PMERR_STOP_DRAW_OCCURRED
 
Example
 
This example uses the GpiDrawSegment function to draw segment 4:
 
POINTL ptlStart = { 0, 0 };
POINTL ptlTriangle[] = { 100, 100, 200, 0, 0, 0 };
 
GpiOpenSegment(hps, 4L);               /* open the segment           */
GpiMove(hps, &ptlStart);               /* move to start point (0, 0) */
GpiPolyLine(hps, 3L, ptlTriangle);     /* draw triangle              */
GpiCloseSegment(hps);                  /* close the segment          */
    .
    .
    .
GpiDrawSegment(hps, 4L);               /* draw segment #4            */
