Thanks to the Stritch Network Folks....

I asked the Stritch Network techs to set up the web server so that it would allow the direct download of .java files. It is done and works. Starting today you will be able to download or directly open .java files from the web. This will make it much easier to use the files from the website.

Changing a Foreground color:

After a little research, I found how to change the foreground color in a JLabel and therefore in the content pane of the kinds of applications we are writing. (Thanks Stephen)

You need to set the Opaqity or opaqueness of the label to change the forground. Note lines 13, 29 and 30 below:



 1 // RedText

 2    import java.awt.*;

 3    import javax.swing.*;

 4

 5     public class RedText extends JFrame

 6    {

 7       private JLabel aLabel;    // JLabel that displays text

 8  

 9    // no-argument constructor

10        public RedText()

11       {

12       // get content pane and set layout to null

13          Container contentPane = getContentPane();

14          contentPane.setBackground( Color.LIGHT_GRAY );      

15          contentPane.setLayout( null );

16    

17         // set properties of application's window

18          setTitle( "REDText Demo" ); // set title bar string

19          setSize( 608, 143 );   // set width and height of JFrame

20          setVisible( true );    // display JFrame on screen

21    

22       // set up aLabel

23          aLabel = new JLabel();

24          aLabel.setText( "I am red text on light gray!!" );

25          aLabel.setLocation( 30, 0 );

26          aLabel.setSize( 550, 88 );

27          aLabel.setFont( new Font( "Serif", Font.PLAIN, 36 ) );

28          aLabel.setHorizontalAlignment( JLabel.CENTER );

29          aLabel.setOpaque(false);

30          aLabel.setForeground(Color.RED);

31          contentPane.add( aLabel );

32       }

33    

34    // main method

35    public static void main( String[] args )

36     {

37       RedText application = new RedText();

38       application.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );

39    

40     } // end method main

41 

42    } // end class RedText

Social Networking & DOPA

Deleting Online Predators Act of 2006
From Wikipedia, the free encyclopedia
The Deleting Online Predators Act of 2006 (DOPA) is a bill (H.R. 5319) brought before the United States House of Representatives on May 9, 2006 by Republican Pennsylvania Representative (R-PA) Mike Fitzpatrick. The bill, if enacted, would amend the Communications Act of 1934, requiring schools and libraries that receive E-rate funding to protect minors from online predators in the absence of parental supervision when using "Commercial Social Networking Websites" and "Chat Rooms". The bill would prohibit schools and libraries from providing access to these types of websites to minors. The bill also would require the institutions to be capable of disabling the restrictions for "use by an adult or by minors with adult supervision to enable access for educational purposes."

The bill is considered controversial because according to its critics the bill could limit access to a wide range of websites, including many with harmless and educational material. Arguments for the bill focus on the fear of adults contacting children on MySpace and similar websites. Many Internet websites, however (ranging from Yahoo to Slashdot to Amazon.com), allow user accounts, public profiles, and user forums, in accord with the bill's definition of "social networking". The bill places the onus upon the Federal Communications Commission to provide clarification.

My daughter pointed out this interesting article on Social networking. Certainly worth a read maybe more action in terms of curriculum...
