I have 2 classes, Model class & Panel class having JTable instance. In that Panel class, I did, model_obj.addTableModelListener(this); This model_obj is passed to the JTable instance. From this same class I am populating row in model class. With an action event for a button, I am inserting row into model. There I call rowInsert function from model class which having, fireTableChanged(new TableModelEvent(this)); /// this = Object of model class. which works fine, calling tableChanged method from my Panel class. This even gives me info, such as, event raised is for insertion. In this tableChanged method, I called updateUI() for Panel. All works with no exception anywhere. But inserted row is not getting displayed over Panel. Initially I am having no rows. Please Note : table object is added to the ScrollPane, which in turn added to Panel. Component addition code is perfect. Where can I be wrong ? waiting impatiently !!!
hi, you don't need to call any repaint or update methods. the model should notify the table on its own: http://java.sun.com/docs/books/tutorial/uiswing/events/tablemodellistener.html "Each JTable [(in the Creating a GUI with JFC/Swing trail)] object has a table model that holds its data. When a table model listener is registered on the table model, the listener is notified every time the table model's data changes. The JTable itself automatically uses a table model listener to make its GUI reflect the current state of the table model." chantal

Thanx guys for your valuable comments. Indeed problem found to be different. I have added table to Panel. ScrollPane to ScrollPane. Since initially table having no rows Panel as well the ScrollPane were at their min position. After I add row to model, I used to get of type Row Added to the Table, but I could never see that added row, until, I dragged my SplitPane below (resize). It was indeed silly thing to have Panel within scrollpane. Thanx.

If your using swing (JTable, JScrollPane, JPanel), then it is necessary to add the table to the scrollpane if you ever want to see any columnheaders. chantal
