C++ (Cpp) refreshRotation Examples

Example #1

File: qgscomposeritem.cpp Project: exlimit/QGIS

void QgsComposerItem::setItemRotation( const double r, const bool adjustPosition )
{
  mItemRotation = r;
  if ( mItemRotation >= 360.0 || mItemRotation <= -360.0 )
  {
    mItemRotation = std::fmod( mItemRotation, 360.0 );
  }

  QgsExpressionContext context = createExpressionContext();
  refreshRotation( true, adjustPosition, context );
}

Example #2
