More lightweight/heaviweigth discussion

The following phrase seems to be a leftover and does not make sense in the current context.

"The disadvantage of lightweight components is slower execution. The advantage is uniform behavior on all platforms."

Swing Origins

I had a recent assignment to find the origin of the name of Swing (Java) and one student submitted this link stating that the name was based off the 1930's dance craze. Can anyone else confirm or deny this claim with sources? I already googled and looked through the Sun website.

Closest reference I can find is from an 1998 version of the Swing website: "Swing was the project name chosen by the developers of the new high-level components. Although these components are now part of the JFC software, the Swing name persists." I would not be surprised if the Swing team chose the name based on the dance (as opposed to the several other meanings of that word). I seem to recall hearing something to that effect at the time, but can't track down a reference. -- BrianDuff

Swing on Vista

Suggest we get a section on (and screenshots of) Swing in Vista - apparently it's rather more than just a port from XP. Some links : http://weblogs.java.net/blog/chet/archive/2006/10/java_on_vista_y.html http://weblogs.java.net/blog/chet/archive/2005/08/mustang_swing_a.html

Lightweight/heavyweight distinction

Was just skimming through the article for some general information on Swing and found the comparison with AWT unclear:

"...every Swing lightweight interface ultimately exists within an AWT heavyweight component because all of the top-level components in Swing ... extend an AWT top-level container."

A little more explanation of the relationship between the two would be helpful: if the AWT components are tied to native OS controls, and the Swing components are extensions of AWT components, how then do the Swing components manage to be "lightweight"? Are these AWT top-level containers so abstract as to not involve any of the "heavyweight" code? Do the Swing components extend them just to retain a consistent interface?

Only the top level components like windows are heavyweight, the components inside them (buttons, scrollbars, text fields, etc) are not - for the most part they're drawn using Java graphics routines. So it means that a JButton exists within a JWindow and therefore within a Window. --Jamoche 18:49, 8 October 2006 (UTC)[reply]

Hello World doesn't run?

I've tried compiling the hello world code, it compiles fine but gives very many errors when run. I've fixed it and would like some feedback.Thatfunkymunki 06:19, 20 March 2006 (UTC)[reply]

All you did was remove the package statement? The package statement is simply a source file organization issue, not a code correctness issue. (The Java package article is in need of some serious work—it doesn't currently provide a whole lot of clarity about the implied directory structure of packages.) I suppose we could add to the article the fact that the package statement implies that the source files are placed in a "helloworld" directory placed in the CLASSPATH, but then again, many IDEs don't require this organization. (Also, when you make a semantic change, such as modifying the source code, you should not mark the edit as minor.) —Doug Bell ^{talk•contrib} 07:25, 20 March 2006 (UTC)[reply]

I think the example isn't great. I have removed the anonymous class, but really it just shows what a poor example it is.. something along these lines would be clearer.. Simonjl

public class HelloWorld  {

    public static void main(String[] args) {
        
        JFrame f = new JFrame ("Hello, World!");
        f.setDefaultCloseOperation (JFrame.DISPOSE_ON_CLOSE);
        f.getContentPane().add (new JLabel("Hello, World!"));
        f.pack();
        f.setVisible(true);
        EventQueue.invokeLater (new Thread());
    } 
    
}

JAVA SWING

Swing is a set of classes that provides more powerful and flexible functionality that is possible with standard and advanced AWT(Abstract Window Toolkit) components.These are not implemented by platform specific code. Instead they are written entirely in Java, therefore, they are platform independent. Fundamentals of swing is the JApplet class that extends the Applet class. Applets that use Swing must be subclasses of the JApplet class —The preceding unsigned comment was added by AbhishekDutta1987 (talk • contribs) 02:22, 1 May 2007 (UTC)[reply]

Hello world

The Hello world example used on this article is not really a Hello world IMHO:

the use of Runnable and threading stuff is not necessary in such a basic program as this one, making the example more complex that it should. Threading stuff vs Swing should be in a new paragraph.
There's too much comments in the code, which should be outside the code, in the paragraph.
Centering the frame in the middle of the screen is also not necessary in this example.

I have no problem to modify the example myself, but I'm asking for comments on this proposal before ;-) Hervegirod (talk) 10:23, 23 February 2008 (UTC)[reply]

since I have received no comment since February (more than one month), I assumed people agree with my proposal. Hervegirod (talk) 12:29, 28 March 2009 (UTC)[reply]

External links

Could someone please have a look at the external links section? The ones that are left after the so-called cleanup from Aug 27th are mostly useless. (A blog with less than 2 dozen entries that was started in May this year remained, but the links to java.sun.com were deleted...) 195.212.29.163 (talk) 14:39, 26 September 2008 (UTC) —Preceding unsigned comment added by 195.212.29.163 (talk) [reply]
