disp_polygonT_disp_polygondisp_polygonDispPolygonDispPolygon (Operator)

Name

disp_polygonT_disp_polygondisp_polygonDispPolygonDispPolygon — Displays a polyline.

Signature

Description

disp_polygondisp_polygondisp_polygonDispPolygonDispPolygon displays a polyline with the row coordinates RowRowRowRowrow and the column coordinates ColumnColumnColumnColumncolumn in the output window. The parameters RowRowRowRowrow and ColumnColumnColumnColumncolumn 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_colorset_colorSetColorSetColor, set_grayset_grayset_graySetGraySetGray, set_drawset_drawset_drawSetDrawSetDraw, set_line_widthset_line_widthset_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(long WindowHandle,
                        long Row1, long Column1,
                        long 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_polygondisp_polygonDispPolygonDispPolygon returns 2 (H_MSG_TRUE).
