title: QTextEdit default value
body: <p>i am using pyqt5 and i am wondering how i can set a default text to a textedit widget? So that it shows for example &quot;Type your name here&quot; and when i type something the text goes away. Like on login pages. I am happy about every answer!</p>
  <p>it should look like this:</p>
