Solution

  • You can get the index of the caret ("cursor") with

    int offset = textArea.getCaretPosition();

    and then convert to a TwoDimensional.Position with

    Position pos = textArea.offsetToPosition(offset);

    From there, pos.getMajor() is the paragraph (line) number (and pos.getMinor() is the index of the caret within the line).
