Recently I had a problem where I wanted to show a popup centered about a node,
so I used a little hack to trigger Window's sizing before it became visible:
popup.setOpacity(0); popup.show(); popup.hide(); popup.setOpacity(1);
I wonder what would happen if you added that line, then did a
popup.sizeToScene() before you did the real show?
