title: QtDesigner: Setting fixed size of QLabel
body: <p>I have a fixed size label on a QtDesigner form. The label is used to display images, let's assume it's used to display thumbnails of 100x100 px. </p>
  
  <p>I can set the size of the label but when I put the label in some layout manager the labels get resized to take the whole space. Even if I do it through the Form > Layout in a Grid. The size of the labels is shrunk.</p>
  
  <p>I believe this is some corner case as labels are not often used to do such things (although they are meant to be able to display images). Is there a workaround to avoid the size of the labels changing when placed in the layout?</p>
