disp_polygonT_disp_polygonDispPolygondisp_polygonDispPolygonDispPolygon (Operator)

Name

disp_polygonT_disp_polygonDispPolygondisp_polygonDispPolygonDispPolygon — Displays a polyline.

Signature

Description

disp_polygondisp_polygonDispPolygondisp_polygonDispPolygonDispPolygon displays a polyline with the row coordinates RowRowRowRowRowrow and the column coordinates ColumnColumnColumnColumnColumncolumn in the output window. The parameters RowRowRowRowRowrow and ColumnColumnColumnColumnColumncolumn have to be provided as tuples. Straight lines are drawn between the given points. The start and the end of the polyline are not connected.

The operators used to control the display of regions (e.g. set_colorset_colorSetColorset_colorSetColorSetColor, set_grayset_graySetGrayset_graySetGraySetGray, set_drawset_drawSetDrawset_drawSetDrawSetDraw, set_line_widthset_line_widthSetLineWidthset_line_widthSetLineWidthSetLineWidth) can also be used with polylines.

Attention

The given coordinates must lie within the window.

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: local (may only be called from the same thread in which the window, model, or tool instance was created).
• Processed without parallelization.

Parameters

Example (C)

/* display a rectangle */

disp_rectangle1_margin1(Hlong WindowHandle,
                        Hlong Row1, long Column1,
                        Hlong Row2, long Column2)
{
  Htuple Row, Col;
  create_tuple(&Row,4) ;
  create_tuple(&Col,4) ;

  set_i(Row,Row1,0) ;
  set_i(Col,Column1,0) ;

  set_i(Row,Row1,1) ;
  set_i(Col,Column2,1) ;

  set_i(Row,Row2,2) ;
  set_i(Col,Column2,2) ;

  set_i(Row,Row2,3) ;
  set_i(Col,Column1,3) ;

  set_i(Row,Row1,4) ;
  set_i(Col,Column1,4) ;

  T_disp_polygon(WindowHandle,Row,Col) ;

}
  

Result

disp_polygondisp_polygonDispPolygondisp_polygonDispPolygonDispPolygon returns 2 (H_MSG_TRUE).
