Re: Code Included: Freeze column

Show all headers | View raw

I'm lost here, can you give me more ideas? Problem: Both horizontal
and vertical scrolling works on the right table. But, vertical
scrolling on the right table does not scroll the left table!

Horizontal scrolling is working on the right table, so I don't think I
should be modifying setAutoResizeMode().

Scrolling the right table vertically does not affect the row that is
highlighted.
So applying your idea via the below code is useless!

SharedClass implements ListselectionListener {
   public void valueChanged (ListSelectionEvent evt){
      int index = evt.getFirstIndex();
      System.out.println ("Row = " + index);
   }
}

listSelectionModel listSelectionModel = scrollTable.getSelectionModel
();
listSelectionModel.addListSelectionListener(new SharedClass());
scrollTable.setSelectionModel(listSelectionModel);
fixedModel.setSelectionModel (scrollTable.getSelectionModel());
