static void HOperatorSet.DispLine(HTuple windowHandle, HTuple row1, HTuple column1, HTuple row2, HTuple column2)

void HWindow.DispLine(double row1, double column1, double row2, double column2)
描述
disp_linedisp_lineDispLineDispLineDispLinedisp_line displays one or several lines in the output
window. A line is described by the coordinates of the start
(Row1Row1Row1Row1row1row_1,Column1Column1Column1Column1column1column_1) and the coordinates of the end
(Row2Row2Row2Row2row2row_2,Column2Column2Column2Column2column2column_2).
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 lines. Several lines can
be displayed with one call by using tuple parameters. For the use of colors
with several lines, see set_colorset_colorSetColorSetColorSetColorset_color。
注意
The starting points and the ending points of the lines
must be in the window.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
