QTextEdit: how to get lines?

[claudio]

Yea, great! This is my code for scanning the blocks on a mouse move event:

for(QTextBlock block = document()->begin(); block.isValid(); block = block.next()) {
    if(block.contains(textpos)) {
      int posinblock = textpos - block.position();
      if(block.layout()->isValidCursorPosition(posinblock)) {
        QTextLine tl = block.layout()->lineForTextPosition(posinblock);
        int linestartpos = block.position() + tl.textStart();
        emit onMouseMoveTextLineStartPos(linestartpos);
      }
      break;
    }
  }

for(QTextBlock block = document()->begin(); block.isValid(); block = block.next()) {
    if(block.contains(textpos)) {
      int posinblock = textpos - block.position();
      if(block.layout()->isValidCursorPosition(posinblock)) {
        QTextLine tl = block.layout()->lineForTextPosition(posinblock);
        int linestartpos = block.position() + tl.textStart();
        emit onMouseMoveTextLineStartPos(linestartpos);
      }
      break;
    }
  }

To copy to clipboard, switch view to plain text mode 

Thanks for your help, patrik08!
