title: java detect clicked buttons
body: <p>I have multiple panels on a JFrame window. I am going to populate each panel differently every time. For example:
  i start the GUI: (image center panel, right panel, bottom panel). Center panel is populated with 20 buttons, right panel with 10 buttons and bottom panel with 3. </p>
  
  <p>second start of the GUI (same gui). Center panel has 50 buttons, right panel has 12 buttons, bottom has 3.</p>
  
  <p>So everytime there is a random number of buttons, impossible to be all uniquely named.
  Given the fact that I don't have a unique name for each button (just a list) I would like to know which buttons were clicked according to the panel they belong to. is that possible? </p>
