JpopupMenu not displaying
hi all,
why the JPopupMenu is not displaying here?
is this line not registering mouseListener
enableEvents(AWTEvent.MOUSE_EVENT_MASK);
import java.awt.AWTEvent;
import java.awt.event.MouseEvent;
import javax.swing.JFrame;
import javax.swing.JMenuItem;
import javax.swing.JPanel;
import javax.swing.JPopupMenu;
import javax.swing.JScrollPane;
import javax.swing.JTable;
publicclass DemoPopUpextends JFrame{
protected JPopupMenu popupMenu =new JPopupMenu();
protected JMenuItem m_mniInsertRow;
protected JMenuItem m_mniInsertScrip;
protected JMenuItem m_mniDeleterRow;
protected JMenuItem m_mniDeleteExpiredScrip;
protected JMenuItem m_mniSetAlert;
JTable tbl =new JTable(100, 8){
public Object getValueAt(int row,int col){
return row+","+col;
}
};
public DemoPopUp(){
m_mniInsertRow =new JMenuItem("Insert a Row");
m_mniInsertScrip =new JMenuItem("Insert a Scrip");
m_mniDeleterRow =new JMenuItem("Delete a Row");
m_mniDeleteExpiredScrip =new JMenuItem("Delete a Expired Scrip");
m_mniSetAlert =new JMenuItem("Set Alert");
popupMenu.add(m_mniInsertRow);
popupMenu.add(m_mniInsertScrip);
popupMenu.add(m_mniDeleterRow);
popupMenu.add(m_mniDeleteExpiredScrip);
popupMenu.add(m_mniSetAlert);
enableEvents(AWTEvent.MOUSE_EVENT_MASK);
JPanel jp =new JPanel();
JScrollPane src =new JScrollPane(tbl);
jp.add(src);
getContentPane().add(jp);
setVisible(true);
pack();
setDefaultCloseOperation(EXIT_ON_CLOSE);
}
publicvoid processMouseEvent( MouseEvent evt )
{
if( evt.isPopupTrigger() )
{
JTable source = (JTable)evt.getSource();
int row = source.rowAtPoint( evt.getPoint() );
int column = source.columnAtPoint( evt.getPoint() );
System.out.println(column);
source.changeSelection(row, column, false,false);
popupMenu.show(evt.getComponent(), evt.getX(), evt.getY());
}
}
publicstaticvoid main(String[] args)
{
new DemoPopUp();
}
}
