Hello
I cannot figure out how to "center" the border title of a JPanel. I did
look in the API and went to the Sun site for beginners........ but I am
still stuck

//in my class I declared
JPanel janswer;

// then I proceeded to make a Jpanel

public void buildAnswerPanel()
{janswer = new JPanel();
janswer.setBackground(Color.white);
janswer.setLayout(new GridLayout(2,0,));

//everything works including the next line
janswer.BorderFactory.createTitledBorder( "Here is my Title");

// however I wish to center the panel title......... so when I try the
following I get an error
janswer.setBorder(BorderFactory.createTitledBorder("Here is my Title
", TitledBorder.CENTER));
}

Please give me an example of how to "justify the title of a border on a
Jpanel"

Many Thanks
Fud

here is the error
cannot resolve symbol
symbol : method createTitledBorder (java.lang.String,int)
location: class javax.swing.BorderFactory

janswer.setBorder(BorderFactory.createTitledBord
er("Here is my Answer ", TitledBorder.CENTER));
^

There's no method named createTitleBorder which takes a String and an
int as parameters. Try
BorderFactory.createTitledBorder(null,"Here is my Answer ",
TitledBorder.CENTER, TitledBorder.DEFAULT_POSITION)

There is no such method. If you check the JavaDocs, you will find the
following createTitledBorder methods in the BorderFactory class:

createTitledBorder(Border)
createTitledBorder(Border,String)
createTitledBorder(Border,String,int,int)
createTitledBorder(Border,String,int,int,Font)
createTitledBorder(Border,String,int,int,Font,Color)
createTitledBorder(String)

Note that createTitledBorder(String,int) is not one of them. You need to
select from the defined methods and supply the correct parameters. I
think you probably want to use createTitledBorder(Border,String,int,int);

Alternatively, you can create the border using a method that does not
specify all of the attributes, then set any additional attributes that
you want using TitledBorder's accessors. For example:

TitledBorder border = BorderFactory.createTitledBorder( "Title" );
border.setTitleJustification( TitledBorder.CENTER );

Indeed there is no such method in BorderFactory (see
http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/BorderFactory.html).
You could try

BorderFactory.createTitledBorder(BorderFactory.createEtchedBorder(),

"Here is my Answer",

TitledBorder.CENTER,
TitledBorder.TOP);

Checking the source code, I see that passing null for the Border argument
will work. Is the behavior documented, or are you depending on internal
implementation details?

You're probably right that it's not documented, at least not explicitly.
I guess, I must have interpreted the javadoc of createTitledBorder
("Adds a title to an existing border, ...") in combination with the
possibility to create compound borders (wrapping a border within another
border) that it should be possible. I've applied it in a number of
applications and it never failed. So I was relying on pragmatics rather
than wisdom ;-)
