title: Issue updating a parent JFrame
body: <p>First, let it be known that I'm new to java and it's quirks. I'm a seasoned programmer with various languages, which may be why I'm stuck...</p>
  
  <p>I have an application that, possibly due to poor design, spawns new JFrames through the users' work-flow. My question is, if there is an event in a spawned JFrame, is it able to contact and pass data or an event to it's parent?</p>
  
  <p>I have read that using a JDialog seems to be the way to design, but let's assume that's not an option. Essentially, JFrame1 contains a JTable with a list of data. An action spawns JFrame2 and a user "does something" that impacts the data in the list in JFrame1. Upon closing JFrame2, is there a way to control the JTable based on JFrame2's close event?</p>
  
  <p>It's a pretty basic concept, I just can't seem to find the mechanism that would allow such an action.</p>
  
  <p>Thanks!</p>
