title: Preventing window from minimizing or closing
body: <p>I would like to create some screen that is displayed every time user login to machine. He would need to inserts his credentials and reason of his login, only then window could be closed. I was thinking about using tkinker, but I can find information how to lock it from closing or minimizing.</p>
  
  <p>EDIT: Note that I'm not asking how to hide buttons, I figured it out. I want to prevent minimizing for e.g.: clicking on different window.</p>
