Hi
I have a question over a simple concept of JTable. I have created
the following sample code of a table where the model of
T1FieldSetTableModel is added to the JTable class. My question is that
since this code is created in Panel.java and I have a separate class
called T1FieldSetModel.java, how do I call the getColumnName to show
the columnindex (i.e) return the string type of columnNames
RowNo,Code,Description ??
In class T1Panel.java - Sample
Object[][] data = { {1, "", "",""," "} };
String[] columnNames =
{"RowNo","Code","Description","Value1","Value2"};
DefaultTableModel model = new DefaultTableModel(data,co=
lumnNames);
T1FieldSetTableModel fsModel = new T1FieldSetTableModel=
();
JTable table = new JTable(fsModel);
table.putClientProperty("terminateEditOnFocusLost", Boole=
an.TRUE);
JScrollPane scrollPane = new JScrollPane( table );
scrollPane.setBounds(100, 100, 50, 50);
aContainer.add(scrollPane);

Here is the following code in my main class T1Panel.java . I am having
a problem on clicking the add Rows button by which I am not seeing the
rows getting added in the Jtable. Can anyone help me here??
In main class T1Panel.java this method addRows was created and called
from the actionEvent method of button class in the same program....
private void addRows(){
Container aContainer=this.t1Frame.getContentPaneContainer();
Object[][] data = { {1, "", "",""," "} };
String[] columnNames =
{"RowNo","Code","Description","Value3","Value4"};
DefaultTableModel model = new DefaultTableModel(data,columnNames);
T1FieldSetTableModel fsModel=new T1FieldSetTableModel();
JTable table = new JTable(fsModel);
fsModel.addRow(fsModel.createRow());
int row = table.getRowCount() - 1;
table.getColumnModel().getColumn(4).setCellEditor(new
DefaultCellEditor(comboBox));
table.changeSelection(row, 0, false, false);
table.requestFocusInWindow();
table.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
table.getColumnModel().getColumn(4).setCellEditor(new
DefaultCellEditor(comboBox));
// Add table and a Button panel to the frame
JScrollPane scrollPane = new JScrollPane( table );
scrollPane.setBounds(100, 100, 500, 150);
aContainer.add(scrollPane);
int maxPanelXPixels = this.panelStats.getMax_X_bounds_pixels();
this.t1Frame.setColumnsWide( (maxPanelXPixels /
IEFrame.COL_WIDTH_PER_CHAR)+3);
this.t1Frame.display();
}

I am not sure what wrong am I doing here and why the rows aren't being
generated?... can someone help me here? point out the mistake in my
code??I have hit a brickwall on this problem
