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 -> long * |

Max (output_control) |
integer -> long * |
| Displayable maximum width. | |
::query_line_width returns H_MSG_TRUE if the window is valid. Otherwise an exception handling is raised.
