title: How do I make a simple solid border around a FlowPane in javafx
body: <p>I'm building a simple app in javafx, and I want to be able to add a border to a FlowPane.</p>
  
  <p>I have a bit more experience in java than javafx so I tried to find the equivalent of <code>.setBorder(BorderFactory.createEmptyBorder(0,0,0,0))</code> but to no avail.</p>
  
  <p>Unfortunately, everything I have found seems to be more complicated than I need. I don't need styles or dashes and that's all I'm finding.</p>
  
  <p>Thanks !</p>
