Adding Action to the Button which is in JTableHeader
Hi, I can able to add a button to the JTableHeader. But i would like to add Action to that Button. When i add Action Listener no action is happening. So Could any one suggest how to solve this problem.
In the below code, You can find i am using one Parser java file. From that Java file i am getting data i need to display in table body.
Here i pasted my complete code:
package src;
import java.awt.Component;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.ArrayList;
import java.util.Iterator;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.AbstractTableModel;
import javax.swing.table.DefaultTableCellRenderer;
import javax.swing.table.TableCellRenderer;
import javax.swing.table.TableColumn;
public class TestTable extends JFrame implements ActionListener
{
public TestTable(){
JTable table = new JTable(this.new ParticipantDataModel());
MyButton select = new MyButton(table,"S_ALL");
table.getColumnModel().getColumn(0).setHeaderRenderer(new MyButton(table,"Select All"));
TableColumn tColumn4 = table.getColumnModel().getColumn(3);
DefaultTableCellRenderer defaultRender = new DefaultTableCellRenderer();
defaultRender.setToolTipText("<html><body>Tool Tip Testing................
Tool Tip Testing................
Tool Tip Testing................</body></html>");
tColumn4.setCellRenderer(defaultRender);
JScrollPane scrollPane = new JScrollPane(table);
add(scrollPane);
setVisible(true);
}
public static void main(String[] args) {
TestTable test = new TestTable();
}
public Object[][] getParticipantData(){
Object[][] data = null;
Parser parse = new Parser();
ArrayList rules = (ArrayList)parse.getRuleInfos("test.xml");
data = new Object[rules.size()][];
int i = 0;
for (Iterator iter = rules.iterator(); iter.hasNext();i++) {
RuleInfo element = (RuleInfo) iter.next();
data = new Object[4];
data[0] = new Boolean(false);
data[1] = element.getRuleName();
data[2] = element.getRuleAlias();
data[3] = element.getRuleDesc();
}
return data;
}
class ParticipantDataModel extends AbstractTableModel{
public Class getColumnClass(int col) {
return getValueAt(0, col).getClass();
}
public String getColumnName(int col) {
return (String) colNames[col];
}
public boolean isCellEditable(int row, int col) {
return true;
}
Object[] colNames = {"Select All","Role Name", "Role Alias", "Description" };
Object[][] colValues = getParticipantData();
public int getColumnCount() {
return 4;
}
public int getRowCount() {
return colValues.length;
}
public Object getValueAt(int row, int col) {
return colValues[row][col];
}
public void setValueAt(Object colValue, int row, int col) {
colValues[row][col] = colValue;
fireTableCellUpdated(row, col);
}
}
public void actionPerformed(ActionEvent e) {
System.out.println(e.getSource());
}
private static class MyButton extends JButton implements TableCellRenderer,ActionListener{
JTable table = null;
public MyButton(){
super();
addActionListener(this);
}
public MyButton(JTable table,String value){
setText(value);
addActionListener(this);
this.table = table;
}
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int col) {
return this;
}
public void actionPerformed(ActionEvent arg0) {
System.out.println(arg0);
}
}
}
Thanks
