示例#1

文件： qgstolerance.cpp 项目： NyakudyaA/QGIS

double QgsTolerance::vertexSearchRadius( QgsMapLayer *layer, const QgsMapSettings &mapSettings )
{
  QSettings settings;
  double tolerance = settings.value( "/qgis/digitizing/search_radius_vertex_edit", 10 ).toDouble();
  UnitType units = static_cast< QgsTolerance::UnitType >( settings.value( "/qgis/digitizing/search_radius_vertex_edit_unit", QgsTolerance::Pixels ).toInt() );
  return toleranceInMapUnits( tolerance, layer, mapSettings, units );
}
