Swing - Using JTabbedPane

Show all headers | View raw

So I'm throwing JTables into JScrollPanes and then adding them as 
new tabs, but when I want to read the selected table again later, I'm 
not sure what to do. Right now the code below seems to be working, 
but I'm not sure if it is a good approach. Also JViewport is a mystery.


int tab = jTabbedPane1.getSelectedIndex();
        
if (tab == -1){
   statusMessageLabel.setText("Error: no tab is selected."); 
   return;
}
        
Component csp = jTabbedPane1.getComponent(0);
Component cvp;
Component cjt;
        
JTable jt = null;
        
if (csp instanceof JScrollPane){
   cvp = ((JScrollPane)csp).getComponent(0);
   if (cvp instanceof JViewport){
       cjt = ((JViewport)cvp).getComponent(0);
       if (cjt instanceof JTable){
           jt = (JTable)cjt;
       }
   }
}
        
if (jt == null){
    statusMessageLabel.setText("Error: selected tab "+ tab + " is not a table.");
    return;
}
