from http://juffed.googlecode.com/svn/trunk/qedit/qtedit.cpp

my own first projekt

as editor now i use only http://www.riverbankcomputing.co.uk/...illa/index.php having all

Qt Code: 
  1. QString TextEdit::GrepTextLines(int startline, int stopline )
  2. {
  3. QStringList  cuttextlist;
  4. cuttextlist.clear();
  5. int xli = 1;
  6. for ( QTextBlock block = document()->begin(); block.isValid(); block = block.next(), xli++) {
  7.    if (xli == startline || xli > startline) {
  8.             if (xli == stopline || xli < stopline) {
  9.             cuttextlist.append(GrepLineFromTxBloc(block));
  10.             ////////qDebug() << "### cat line GrepTextLines  " << xli;
  11.             }
  12.    }
  13. }
  14. return cuttextlist.join("\n");
  15. }
  16.  
  17. QString TextEdit::GrepLineFromTxBloc( QTextBlock block )
  18. {
  19.         QString linetext = "";
  20.         if ( m_tabSpaces )   /* if tabulator key on to indent text ? */
  21.         {
  22.             int nbSpaces = tabStopWidth() / fontMetrics().width( " " );
  23.             for (int i = 0; i<nbSpaces; i++)  {
  24.                 linetext.append( " " );
  25.             }
  26.             linetext.append(block.text());
  27.  
  28.         } else {
  29.         linetext.append(block.text());
  30.         }
  31.  
  32.   return linetext;
  33. }
