C++ (Cpp) updateSimplificationPreview Examples

Example #1

File: qgsmaptoolsimplify.cpp Project: chhao91/QGIS

void QgsMapToolSimplify::setTolerance( double tolerance )
{
  mTolerance = tolerance;

  QSettings settings;
  settings.setValue( "/digitizing/simplify_tolerance", tolerance );

  if ( !mSelectedFeatures.isEmpty() )
    updateSimplificationPreview();
}

Example #2

File: qgsmaptoolsimplify.cpp Project: chhao91/QGIS

void QgsMapToolSimplify::setToleranceUnits( int units )
{
  mToleranceUnits = ( QgsTolerance::UnitType ) units;

  QSettings settings;
  settings.setValue( "/digitizing/simplify_tolerance_units", units );

  if ( !mSelectedFeatures.isEmpty() )
    updateSimplificationPreview();
}

Example #3

File: qgsmaptoolsimplify.cpp Project: CS-SI/QGIS

void QgsMapToolSimplify::setToleranceUnits( QgsTolerance::UnitType units )
{
  mToleranceUnits = units;

  QgsSettings settings;
  settings.setValue( QStringLiteral( "digitizing/simplify_tolerance_units" ), units );

  if ( !mSelectedFeatures.isEmpty() )
    updateSimplificationPreview();
}
