That's nice.

What happened to all your posts?

If you have issues with the posts of multiple people, the issue might not
be on their eind.

With so many of clusardi2k's posts deleted, I am unable to follow 
the thread:

I'm sure that is true, but what does it have to do with this thread?

On this thread, you have addressed two different people and asked about
their posts, Haircuts and John Matthews. From the context, I'm now guessing
the first one was due to not having a post of Haircuts left to reply to ?

Either way, it does seem to be on 'your' end (Google) - the posts are still
visible on my news server, and nothing about them seems special or unusual.

Looking at the attributions, which your posts preserved, you can see that 
both questions were addressed to the same person.

> the first one was due to not having a post of Haircuts left to reply to ?

It was due to every post of Haircuts' being marked "This message has been deleted."

Something to which John Matthews also alluded in response to your post.

Thank you. That is helpful to know.

Still, for even GG to report that the messages have been deleted, someone 
took an affirmative action to delete them. So I took the reasonable action 
of asking the poster what happened, under the hypothesis that they initiated
the deletion. The answer I got was tangential at best, and completely 
devoid of useful content, so I repeated the question - to the same person.

So I ask Haircut this: Did you in some fashion "delete" your posts?

#24208

I have modified the code at the below link. Everything seems to work
except horizontal scrolling across the two tables:
http://www.java2s.com/Code/Java/Swing-Components/FixedTableColumnExam....

Again, at run-time (via the routine attached to the timer) the
project
will add different data to the bottom of each table. The bottom row
is
highlighted in each table. The frozen columns are doing what they're
suppose to.


But, when I use the scrollbar on the right table, the left table does
not move.


Here is a non-compilable summary of the resulting code. (The timer
class is not there) Can you get the left table to match the scrolling
on the right table?


Thanks


package test;

class Test extends JFrame{
  public static FixedModel fixedModel;//FixedModel extends
AbstractTableModel see below
  public static ModelWithScrollbar mainModel;//ModelWithScrollbar
extends AbstractTableModel see below
  public static JTable fixedTable;  //Has the frozen columns
  public static JTable scrollTable; //Has a visible scrollbar


  public Test (){

    t.startTimer();

    this.setVisible(true);
    this.setTitle ("An example");

    fixedModel = new FixedModel ();

    fixedTable = new JTable (fixedModel){
    @Override
    public void valueChanged(ListSelectionEvent e){
      super.valueChanged(e);
      checkSelection(true);
    }
   };

   mainModel = new ModelWithScrollbar();

   scrollTable = new JTable (mainModel){
   @Override
   public void valueChanged(ListSelectionEvent e){
     super.valueChanged(e);
     checkSelection(false);
   }
  };


   Dimension dimension = new Dimension(0,0);
   fixedTable.getTableHeader().setPreferredSize(dimension);
   scrollTable.getTableHeader().setPreferredSize(dimension);

   fixedTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
   scrollTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

   fixedTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
   scrollTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

   scrollTable.setFocusable(false);

   JScrollPane jScrollPane1 = new JScrollPane(scrollTable);

   JViewport viewport = new JViewport();
   viewport.setView(fixedTable);
   viewport.setPreferredSize(fixedTable,getPreferredSize());
   jScrollPane1.setRowHeaderView(viewport);

 
jScrollPane1.setCorner(JScrollPane.UPPER_LEFT_CORNER,fixedTable.getTableHea­
der());

There is no anonymous class here. Why the comment?

If it's not an annonymous class what is it called.

If by "it" you mean the block with the 'for' loop in it, that is an initializer. 
It is not any kind of class, let alone an anonymous one.

It is also a bug. You are using an instance initializer to initialize a static 
construct.

That means that every instance of that class, should there ever be more 
than one, will add another 90 items to the 'columnNames' collection, resulting 
in a total size in excess of 90.

It is usually a bad idea to initialize a static structure in an instance context.

Study the following terms to be clear on these matters: "initializer" (both "static initializer" 
and "instance initializer"), "class", "anonymous class", "static member".

Let me try to clarify the problem, when I use the vertical
scrollbar on the right table, the left table does not move.

Any assistance would be greatly appreciated!
