描述
set_line_styleset_line_styleSetLineStyleSetLineStyleSetLineStyleset_line_style defines the output pattern of the margin of
regions and of XLD contours. The information is used by operators like
disp_regiondisp_regionDispRegionDispRegionDispRegiondisp_region, disp_linedisp_lineDispLineDispLineDispLinedisp_line, disp_polygondisp_polygonDispPolygonDispPolygonDispPolygondisp_polygon etc. The
current value can be queried with get_line_styleget_line_styleGetLineStyleGetLineStyleGetLineStyleget_line_style。StyleStyleStyleStylestylestyle contains up to five pairs of values. The first value is
the length of the visible contour part, the second is the length of
the invisible part. The value pairs are used cyclical for contour
output.
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。

示例（HDevelop）
* stroke line: X-Windows
set_line_style(WindowHandle,[20,7])
* point-stroke line: X-Windows
set_line_style(WindowHandle,[20,7,3,7])
* passing line (standard)
set_line_style(WindowHandle,[])
示例（C）
Htuple LineStyle;
/* stroke line: X-Windows */
create_tuple(&LineStyle,2);
set_i(LineStyle,20,0);
set_i(LineStyle,7,1);
T_set_line_style(WindowHandle,LineStyle);
destroy_tuple(LineStyle);
/* point-stroke line: X-Windows */
create_tuple(&LineStyle,4);
set_i(LineStyle,20,0);
set_i(LineStyle,7,1);
set_i(LineStyle,3,2);
set_i(LineStyle,7,3);
T_set_line_style(WindowHandle,LineStyle);
destroy_tuple(LineStyle);
/* passing line (standard) */
create_tuple(&LineStyle,0);
T_set_line_style(WindowHandle,LineStyle);

结果
set_line_styleset_line_styleSetLineStyleSetLineStyleSetLineStyleset_line_style returns 2 (
H_MSG_TRUE)
if the parameter is
correct and the window is valid.否则将抛出异常。
