Can not clear paragraph in QTextEdit

I'm using a QTextEdit for user input. For some reason I can't clear it properly, I always end up with a blank paragraph (the cursor is on the 2nd line).. I've tried every way I can think off, and nothing seems to work:

Code:

---

inputEdit->clear();

---

Code:

---

inputEdit->setHtml( "" );

---

Code:

---

inputEdit->setPlainText( "" );

---

Code:

---

QTextCursor cursor( inputEdit->document() );
 cursor.select( QTextCursor::Document );
 cursor.removeSelectedText();
 cursor.clearSelection();
 cursor.movePosition( QTextCursor::Start );
 inputEdit->setTextCursor( cursor );

---

None of these seem to actually clear the text edit completely, using editInput->toHtml() always shows a HTML document with a blank paragraph in it.. what am I doing wrong here?

Thanks.
