query_line_widthquery_line_widthQueryLineWidthQueryLineWidth (Operator)

Name

query_line_widthquery_line_widthQueryLineWidthQueryLineWidth — Query the possible line widths.

Signature

query_line_width( : : : Min, Max)

Herror query_line_width(Hlong* Min, Hlong* Max)

Herror T_query_line_width(Htuple* Min, Htuple* Max)

void QueryLineWidth(HTuple* Min, HTuple* Max)

static void HInfo::QueryLineWidth(Hlong* Min, Hlong* Max)

static void HOperatorSet.QueryLineWidth(out HTuple min, out HTuple max)

static void HInfo.QueryLineWidth(out int min, out int max)

Description

query_line_widthquery_line_widthQueryLineWidthQueryLineWidthQueryLineWidth returns the minimal (MinMinMinMinmin) and maximal (MaxMaxMaxMaxmax) values of widths of region border which can be displayed. Setting of the border width is done with set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidth. Border width is used by operators like disp_regiondisp_regionDispRegionDispRegionDispRegion, disp_linedisp_lineDispLineDispLineDispLine, disp_circledisp_circleDispCircleDispCircleDispCircle, disp_rectangle1disp_rectangle1DispRectangle1DispRectangle1DispRectangle1, disp_rectangle2disp_rectangle2DispRectangle2DispRectangle2DispRectangle2 etc. if the drawing mode is “margin” (set_drawset_drawSetDrawSetDrawSetDraw(::WindowHandle,'margin':)).

Execution Information
