C++ (Cpp) addPaperItem Examples

Example #1

File: qgscomposition.cpp Project: Nald/Quantum-GIS

void QgsComposition::setNumPages( int pages )
{
  int currentPages = numPages();
  int diff = pages - currentPages;
  if ( diff >= 0 )
  {
    for ( int i = 0; i < diff; ++i )
    {
      addPaperItem();
    }
  }
  else
  {
    diff = -diff;
    for ( int i = 0; i < diff; ++i )
    {
      delete mPages.last();
      mPages.removeLast();
    }
  }

  // update the corresponding variable
  QgsExpression::setSpecialColumn( "$numpages", QVariant(( int )numPages() ) );

  emit nPagesChanged();
}

Example #2

{
  setBackgroundBrush( Qt::gray );
  addPaperItem();

  mPrintResolution = 300; //hardcoded default
  loadSettings();
}
