名称

disp_polygonT_disp_polygonDispPolygonDispPolygondisp_polygon — Displays a polyline.

参数签名

disp_polygon( : : WindowHandle, Row, Column : )

描述

disp_polygondisp_polygonDispPolygonDispPolygonDispPolygondisp_polygon 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_colorSetColorSetColorSetColorset_color, set_grayset_graySetGraySetGraySetGrayset_gray, set_drawset_drawSetDrawSetDrawSetDrawset_draw, set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidthset_line_width) can also be used with polylines.

注意

The given coordinates must lie within the window.
