title: Add widgets inside pushButton?
body: <p>Hi I’m still relatively new to PySide2 and setting up some UIs inside maya . 
  Is it possible to have a QPushButton which has other widgets as children ?</p>
  
  <p>For instance I want to make a pair of QPushButtona side by side that turn each other toggled on and  off when either is clicked , each should have a spinBox inside them . The spinBox is disabled if it’s parent button is ‘off’</p>
  
  <p>I was going to make a simple button class which can toggle it’s counterpart off , so that bit is straightforward , but I can’t see a way to put the spinBox inside it too, maybe something I’ve missed ? Can I add a layout to my button then add widgets inside ?</p>
  
  <p>Thanks for any help </p>
  
  <p>Ben </p>
