Description Steve Witt CLA 2003-07-01 11:41:40 EDT
Eclipse shows errors on method calls to setText and getText in inner class 
DefaultLookupField.  I have added the code for class LookupTextField and 
EnabledTextField.  These errors only happen when the inner class extends a 
class that extends another class.  This is the same error message as bug 32342 
which has been marked as resolved in 2.1 RC1

public class Enclosing {
  
    public void setText(Object text) {
    }
    
    public String getText() {
       return "";
    }
    
    class DefaultLookupTextField extends LookupTextField {
        DefaultLookupTextField(int columns, boolean edit) {
            super(columns, edit);
        }
        public void setValue(Object value) {
            if (value != null) {
                setText(value.toString());
            } else {
                setText(null);
            }
        }
     
        public Object getValue() {
            return getText();
        }
    }
}

public abstract class LookupTextField extends EnabledTextField {


    public LookupTextField(int columns, boolean edit) {
        
    }

    public abstract void setValue(Object value);

    public abstract Object getValue();

}


import javax.swing.JTextField;;

public class EnabledTextField extends JTextField  {

 
    /**
     * Sets the text of the textfield
     * @param text sets the text fo the textfield
     */
    public void setText(String text) {
 
    }

}

Bug 32342 was indeed a bug, but this behavior is intended in 1.3 compliant 
mode. javac 1.3.1 will also report problems:

Enclosing.java:16: setText(java.lang.String) is inherited from EnabledTextField 
and hides method in
outer class Enclosing.  An explicit 'this' qualifier must be used to select the 
desired instance.
                setText(value.toString());
                ^
Enclosing.java:18: setText(java.lang.String) is inherited from EnabledTextField 
and hides method in
outer class Enclosing.  An explicit 'this' qualifier must be used to select the 
desired instance.
                setText(null);
                ^
Enclosing.java:23: getText() is inherited from javax.swing.text.JTextComponent 
and hides method in o
uter class Enclosing.  An explicit 'this' qualifier must be used to select the 
desired instance.
            return getText();
                   ^
4 errors

If you switch our compliance setting to 1.4, then the problem will go away 
since in 1.4 mode, the inherited implementation is always privileged.
