Repainting Problem(please help)

[john von]

Really need your help guys, im working on this for days now. I created sort of mock up of what im really actually doing. Im really working on a Table and a Spit Pane. Just to present to you as brief as possible i wrote a two table instead. The real issue is I can't seems to resolve on repainting a panel. The buttons are located in another class, while the panel to repaint is in separate class. When i click a the button one, it should present the table one and button two on table two. .

I really appreciate any help. Here are the codes of 3 classes. You may ignore the table model method below

//import statement
public class MainFrame extends JFrame
{
static Norte north;
static Center center;
 
public static void main(String args[])
{
new MainFrame();
}
 
public MainFrame()
{
super("My Title");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
north = new Norte();
center = new Center(north);
 
JPanel mainPanel = new JPanel();
mainPanel.setLayout(new BorderLayout());
mainPanel.add("North", north);
mainPanel.add("Center", center);
setContentPane(mainPanel);
 
pack();
show();
}
 
public Dimension getPreferredSize()
{
return new Dimension(700, 500);
}
}

//import statement
public class Center extends JPanel implements ActionListener
{
JButton buttonOne = new JButton("Table One");
JButton buttonTwo = new JButton("Table Two");
 
Norte norte;
 
public Center(Norte north)
{
norte = north;
JPanel buttons = new JPanel();
buttonOne.addActionListener(this);
buttonTwo.addActionListener(this);
buttons.add(buttonOne);
buttons.add(buttonTwo);
add(buttons);
}
 
public void actionPerformed(ActionEvent e)
{
Object source = e.getSource();
 
if (source == buttonOne)
{
norte.x="One";
norte.setTable();
}
else if (source == buttonTwo)
{
norte.x="Two";
norte.setTable();
}
}
}

//import statement
public class Norte extends JPanel
{
JTable onTable;
JTable table1;
JTable table2;
String x = null;
 
public Norte()
{
super(new GridLayout(1,0));
JLabel headTitle = new JLabel("Monitoring Tool");
JPanel titlePane = new JPanel();
 
setTable();
 
titlePane.setLayout(new BoxLayout(titlePane, BoxLayout.Y_AXIS));
titlePane.add(headTitle);
titlePane.add(onTable);
 
add(titlePane); 
 
}
 
JTable getTableOne()
{
System.out.println("ONE");
table1 = new JTable(new TableModelOne());
table1.setShowVerticalLines(false);
table1.setPreferredScrollableViewportSize(new Dimension(700, 500));
table1.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
return table1;
}
 
JTable getTableTwo()
{
System.out.println("TWO");
table2 = new JTable(new TableModelTwo());
table2.setShowVerticalLines(false);
table2.setPreferredScrollableViewportSize(new Dimension(700, 500));
table2.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
return table2;
}
 
public void setTable()
{
if (x == "One") onTable = getTableOne();
else onTable = getTableTwo();
repaint();
}
 
class TableModelOne extends AbstractTableModel 
{
private String[] columnNames = {"Date",
"Last Name",
"First Name"};
private Object[][] infos = {
{"03/23/02", "Gates", "Bill"},
{"03/23/02", "Jobs", "Steve"}
};
 
public int getColumnCount() 
{
return columnNames.length;
}
 
public int getRowCount() 
{
return infos.length;
}
 
public String getColumnName(int col) 
{
return columnNames[col];
}
 
public Object getValueAt(int row, int col) 
{
return infos[row][col];
}
 
public Class getColumnClass(int c) 
{
return getValueAt(0, c).getClass();
}
 
}
 
class TableModelTwo extends AbstractTableModel 
{
private String[] columnNames = {"Date",
"Nick",
"Fave Color"
};
private Object[][] infos = {
{"03/23/01", "The Pearl", "Red"},
{"07/03/02", "Korean Dragon", "Pink"},
{"03/22/04", "Numero Uno", "Blue"}
};
 
public int getColumnCount() 
{
return columnNames.length;
}
 
public int getRowCount() 
{
return infos.length;
}
 
public String getColumnName(int col) 
{
return columnNames[col];
}
 
public Object getValueAt(int row, int col) 
{
return infos[row][col];
}
 
public Class getColumnClass(int c) 
{
return getValueAt(0, c).getClass();
}
 
}
}

Your code won't work because it doesn't ever change the tables.

You can't just change onTable and have the JFrame automatically change too. You need to remove the current JTable from the contentPane and then add the one you are trying to show.

Another, possibly easier way to do this, is use a CardLayout manager. It will let you swap the entire panel, regardless of how many components you add to it.

You also don't need to explicitly create a JPanel and then do a setContentPane. Just do a getContentPane() and add your components to it. Saves creating a JPanel.

HTH!
