title: Display popup JFrame under JTable cell?
body: <p>I've gotten a lot of experience with JTables in the past few months, and I've gotten a grip on ActionListeners and creative implementations. However, there's one thing I can't figure out. </p>
  
  <p>When a cell is clicked for editing on a certain column, I want to popup a tiny JFrame below it that manipulates the cell value, much like a JComboBox. I got everything working, however, I cannot get the form to position EXACTLY below the JTable cell (technically, I want the bottom-left corner of the cell to be top-left corner of the popup. I tried using "getCellRect(...)" but it is not yielding me results or proper coordinates of the corners. </p>
  
  <p>So right now I am using MousePointer.getMousePointerInfo() to display the popup where the mouse is clicked within that cell. But it's not ideal as I want it to be fixed under the cell rather than following the cursor.</p>
  
  <p>Any suggestions on how I can do this?</p>
