Query the possible line widths.
query_line_width returns the minimal (Min) and maximal (Max) values of widths of region border which can be displayed. Setting of the border width is done with set_line_width. Border width is used by operators like disp_region, disp_line, disp_circle, disp_rectangle1, disp_rectangle2 etc. if the drawing mode is "margin" (set_draw(::WindowHandle,'margin':)).
|
Min (output_control) |
integer -> integer |
| Displayable minimum width. | |
|
Max (output_control) |
integer -> integer |
| Displayable maximum width. | |
query_line_width returns 2 (H_MSG_TRUE) if the window is valid. Otherwise an exception handling is raised.
query_line_width is reentrant and processed without parallelization.
