Hi
  I have this source:
import java.awt.*;
import javax.swing.*;
import javax.swing.plaf.basic.BasicComboPopup;

class MyComboPopup extends BasicComboPopup {
        public MyComboPopup( JComboBox combo ) {
            super(combo);
        }
        public void show() {
            //super.show();

        }
        /*public void setVisible(boolean b){
                int index=comboBox.getSelectedIndex();
                Rectangle cellBounds = list.getCellBounds(index,
index);
                scroller.getVerticalScrollBar().setValue(cellBounds.y);
        }*/
    }

If i compile with jdk1.4.2, no warning.
If i use jbuilder 2005 to compile, it give me these:
"Frame1.java": [deprecation] show() in java.awt.Component has been
deprecated at line 50, column 9
There have been deprecation warnings. Please consult the documentation
for a better alternative.

But suppose jbuilder 2005 is using jdk1.4.2 to compile too, then why
it give me this warning?

thanks
