[news.eclipse.platform.rcp] Re: Changing contents of ComboCellBoxEditor

[Allen Young <allenmacyoung@xxxxxxxxx>]

Hi Swapnil,

That is just the case I was talking about. You may need some code like follows, 
say your model class is MyModel.

tableViewer.addSelectionChangedListener(new ISelectionChangedListener(){
   public void selectionChanged(){
       MyModel myModel = (MyModel)((IStructuredSelection)tableViewer.getSelection).getFirstElement();
       if(...) // row1 selected {
           comboBoxCellEditor.setItems(new String[]{"A", "B", "C"});
       }else{
           comboBoxCellEditor.setItems(new String[]{"A", "B"});
       }
   }
});


I think you can implement the logic for determine whether you should set 
[A,B,C] or [A,B].
