Event-Dispatch Thread Rules for Swing UIs

Jeff Friesen — Thu, 26 May 2011 15:42:25 -0400

The event-dispatch thread (EDT) is a special background thread for processing events that originate from the Abstract Window Toolkit's event queue. Update events cause user interface (UI) components to redraw themselves, and input events originate from input devices such as the mouse and keyboard.

Swing is a single-threaded UI toolkit that uses the EDT to update and send input events to components.

Should JavaFX be put down?

Josh Fruhlinger — Mon, 22 Feb 2010 17:41:27 -0500

One of (several) things I'm cranky about on this blog is JavaFX. Last December I asked if anyone knew of honest-to-goodness production JavaFX apps in the wild; in particular, as I emphasized in a later post, I wanted to know about JavaFX ads that run within a browser windows, as do most apps written in Flash and Silverlight (the technologies against which JavaFX ostensibly competes).

How to convert Html to Image using Java

arthikbabu — Wed, 04 Nov 2009 09:16:35 -0500

Hi All,
I need to convert a GWT(Google web toolkit) UI to the image file.
Can anyone give me a suggestions to proceed?

I have googled and I found most of the thing with respect to ActiveX
controls. I am not supposed to use ActiveX.

I have looked some AWT / swing coding to convert the html page to image but i am not able to get the full website or when i try some site to convert as a image then it not rendered fully.

Thanks

Java isn't dead -- it's just fossilizing

Josh Fruhlinger — Fri, 02 Oct 2009 00:11:44 -0400

So here's a thing that everyone thought was going to be in Java 7 and now isn't -- the Swing Application Framework (which in January I called a JSR to watch in 2009, whoops). Work on it hasn't progressed, now it's being pushed back to Java 8 maybe, etc. It wasn't really a core bit of the language, though it would have given heart to those worried that Sun was done with Swing.

Deploying Swing and JavaFX applications to the masses

Tue, 21 Apr 2009 19:12:14 -0400

Sun's (and now Oracle's) desires for Java/Swing's and JavaFX's success on the client depend upon how easy it is for the average user to install the appropriate version of Java/JavaFX on their platform. Furthermore, these desires depend upon browsers being able to launch Swing and JavaFX applications without problems.

Enriching your Swing-based user interfaces

Tue, 14 Apr 2009 15:34:29 -0400

You're developing a Swing application that will be delivered to your company's clients. The application's user interface consists of several screens, starting with a login screen in which the user must enter a user ID and a password. After clicking the screen's LOGIN button, the application validates the entered credentials in some fashion, and (assuming they are valid) takes the user to the second screen.

Listing 1 codifies a simplistic version of this application.

Listing 1: PoorUIApp.java

The Swing Cookbook

Tue, 10 Mar 2009 15:26:28 -0400

Ian Darwin's Java Cookbook presents a collection of recipes for solving hundreds of problems that Java developers encounter. For example, in the first edition, one of Chapter 2's recipes discusses how to use the classpath effectively. To the best of my knowledge, O'Reilly hasn't published a similar cookbook that deals exclusively with Swing.

The future of Swing: Sun responds, and throws down the gauntlet

Two roads diverge in the Java GUI wood: More Swing vs. JavaFX

Josh Fruhlinger — Thu, 29 Jan 2009 20:04:39 -0500

We've discussed here before the brewing battle between Swing and JavaFX for the hearts and minds of desktop Java GUI developers. Will the two technologies develop in parallel, each with their own areas of specialization, or will JavaFX come to supplant Swing -- and if the latter occurs, will it be an organized and open effort, or will it happen surreptitiously? There are a couple of blog posts that recently went up on the subject:

Swing Website Thumbnails

old-dan-tucker — Sun, 11 Jan 2009 11:09:38 -0500

Hi,

Would anyone have some advice on dynamically retrieving thumbnail representations of a web page to display in a swing application. I realise that this could be an expensive feature (retrieval + scaling), do you think it is feasible?

Thanks.

Two JSRs to watch in 2009

Josh Fruhlinger — Fri, 09 Jan 2009 00:24:45 -0500

Nobody took my bait to prognosticate on the future of Java, so I thought I'd highlight a couple of JSRs coming down the pipe that look mildly interesting. Apparently not everyone is ready to abandon Swing for JavaFX, becuase JSR 296 aims to make Swing development a lot easier. The goal is to make Swing easier by putting the boilerplate code into template methods.

Moving from Swing to JavaFX through the back door

Josh Fruhlinger — Tue, 23 Dec 2008 11:02:42 -0500

A few weeks ago I discussed the idea that JavaFX might, in practice, be Swing 2.0, in that it would be Sun's primary Java UI toolkit from here on in. This is interesting and perhaps quite healthy in the long run -- but like all major shifts, it's probably one that should be laid out explicitly for stakeholders so they can start planning for it now.

Making Progress With Swing's Progress Monitoring API

Core Java Technologies Tech Tips — Mon, 15 Dec 2008 12:35:35 -0500

by Jennie Hall
Updated Jan. 23, 2009

In this tip, you'll learn how to use Swing's progress indicator support to monitor and report on the progress of long-running operations. It is a good practice to keep users informed as they interact with an application; one way to do this is with a progress bar. A progress bar is an animated image that indicates the degree of completion of a given task. The animation typically looks like a rectangular bar that fills in as the task becomes more complete.

JavaFX = Swing 2.0

Josh Fruhlinger — Thu, 11 Dec 2008 04:35:21 -0500

OK, so recall my note from last month on Sun's de-funding of SwingX, and how this indicates the ascendancy of JavaFX as Java's preferred UI. Well, this gets elaborated in a much more interesting fashion by Richard Bair in an interview on Kirill Grouchnikov's always great Pushing Pixels blog. Here's the key bit, as Bair fields a question on whether he think backwards compatibility has held Swing back:

JavaFX released. Finally.

JavaFX 1.0 made its debut a few days back amid high hopes and a sea of doubt — some in the Java community believe JavaFX could become “the application environment for the Java platform,” while others say Sun has made nothing but mistakes on the client side, and JavaFX is too little, too late.

Bright idea: A Swing-to-JavaFX converter

Josh Fruhlinger — Wed, 04 Jun 2008 17:01:50 -0400

Despite the waning of my fascination with JavaFX, I admit that I was intrigued when I saw the headline "Swing to FX converter" pop up in my RSS reader. Unfortunately, the post on Vaibhav Chaudhary's blog is really more of a "gee, wouldn't it be neat if there was one" kind of thing. It would be neat, as it could be a method for funneling Java desktop apps straight to the Web.
