get_line_widthT_get_line_widthGetLineWidthGetLineWidthget_line_width — Get the current line width for contour display.

Signature

get_line_width( : : WindowHandle : Width)

Herror T_get_line_width(const Htuple WindowHandle, Htuple* Width)

void GetLineWidth(const HTuple& WindowHandle, HTuple* Width)

double HWindow::GetLineWidth() const

static void HOperatorSet.GetLineWidth(HTuple windowHandle, out HTuple width)

double HWindow.GetLineWidth()

def get_line_width(window_handle: HHandle) -> float

Description

get_line_widthget_line_widthGetLineWidthGetLineWidthget_line_width returns the line width for region display in the window. It is used by operators like disp_regiondisp_regionDispRegionDispRegiondisp_region, disp_linedisp_lineDispLineDispLinedisp_line, disp_polygondisp_polygonDispPolygonDispPolygondisp_polygon, etc. WidthWidthWidthwidthwidth is set with the operator set_line_widthset_line_widthSetLineWidthSetLineWidthset_line_width. WidthWidthWidthwidthwidth is only important for displaying the contour of objects.

Execution Information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Processed without parallelization.

Parameters

Result

get_line_widthget_line_widthGetLineWidthGetLineWidthget_line_width returns 2 ( H_MSG_TRUE) if the window is valid. Otherwise an exception is raised.
