Java::Swing 0.13

Java::Swing provides a Perl extension providing direct access to the Java Swing API.

Though you can write a Java program which is driven by Perl, some people may prefer to keep their Perl pure. This package lets you do that in manner similar to the way Perl/Tk and Gtk2:: provide access to their underlying libraries. This lets us code in our favorite language, while using the graphical interface capabilities of Java Swing.

Once you use Java::Swing, you can refer to javax.swing classes by their class name alone as if it name were a Perl package name. All class methods, including constructors, can be called as normal through this Perl package name.

But, if you like, you may also use Java::Swing named attribute construction, as shown for the second JTextField above. Simply supply a hash reference whose keys are attributes of the class with the proper values. Your object will be constructed by calling the empty argument constructor. Then the attribute values will be supplied by calling set accessors. So columns => 10 will translate into setColumns(10).

As of version 0.12, you may add an Object attribute to the constructor hash. Then Java::Swing will call the constructor on the underlying class which expects it, and then call set accessors for any additional attributes.
