[Qt-interest] QTextCursor::insertBlock() at the beginning of a QTextEdit will prepend an empty line

  Use Qt's ability to display HTML text?

  So without doing any fancy Qt-specific text formatting,
  just set the QTextEdit to contain:

    <center>Centered Line</center>Non centered line

  Remember, though, that if you don't explicitly tell
  Qt that this is an HTML text block, it will use its
  "heuristics" to determine whether it's plain text or
  HTML text. That means that you must have an HTML tag
  (of any kind) within the first line of the text you
  write to the block, otherwise Qt will consider it
  to be plain text and all of your HTML tags will be
  displayed rather than acted-upon.

Hi,

I'm trying to make the first line in a QTextEdit centered by using this sample code:

  QTextEdit e;
  QTextCursor cursor(e.textCursor());
  QTextBlockFormat fmt;
  fmt.setAlignment(Qt::AlignHCenter);
  cursor.insertBlock(fmt);
  cursor.insertText("Centered line");
  cursor.insertBlock(QTextBlockFormat());
  cursor.insertText("Non centered line");
  e.setTextCursor(cursor);

My problem is I get an empty line before the centered line. Seems the only way to
hack around it is to set the cursor position to 0 after I insert all the text
then use QTextCursor::deleteChar().

Any better way ?

Cheers,
