title: How to have a fixed-size layout that also keeps the window from resizing?
body: <p>I have a container widget. </p>
  
  <p>It's size policies are "Fixed" (both vertical and horizontal).
  it has setMaxmimumWidth and setMaximumHeight defined.</p>
  
  <p>I put an QHBoxLayout container there. adding widgets to it (with fixed width/height too).
  But when i call "Show", none of this gets respected. The height is random almost, doesn't match any of the internal widgets in the layout, twice the size of the tallest item, <strong>and the width of my container is stretched far beyond the fixed width I set it.</strong></p>
  
  <p>What am I missing? Why can't the container stay with fixed width/height as I defined it? why is the layout interfering with it and not respecting its constraints?</p>
