I love keyboard shortcuts. I hate the mouse. I wish that Web applications would offer more keyboard shortcuts a la Gmail, and wondered if there could be a generic way to tie keys to actions in an app. There are things such as accessKey, but we need more.

I share the opinion of Dion. I think we need a good key bindings library for GWT.

Custom events as API end points for key bindings and more

The in place editor is one of the simplest yet powerful feature brought by Ajax. I wrote two such editors last year, using javascript and Prototype as an exercise. Recently I started to study GWT more in depth and I found fun to write a GWT version of the in place editor.

Jeff Bolle :

In a variety of views I would like to give the user the option of
"popping out" the current data detail view, much the same way that
GMail allows you to pop out the e-mail composition window.  I would
like to retain the full and normal use of the classes and
functionality in the popout window.  Basically, I want to load a
class, ExternalViewer, in the popout window.  I am not looking for a
panel within the root window, but a true separate browser window.

Dan Morill gives a very good solution for this design problem.

Modules and HTML

It's Wednesday, and you have had it up to here with the weather.  There's nothing on TV and you've gone out for so many walks, you can't even get your dog to look you in the eye without him hiding under the kitchen table.  You have time on your hand, so you decide you want to see how easy it is to set the status bar text when hovering over a link in GWT (why?  don't ask why, let's just pretend for a second).  You settle on three possible approaches...

GWT Hyperlink and the Mouse That Went Over

Trying to use Maven2 to build a GWT project, here is the simplest pom.xml I came up with.

The release of Java version 5 has provided us with some interesting and useful new ways to do things that would usually require a lot of effort, for example the new for-each loop and varargs.

There is another way to pass a variable amount of arguments to a method by just using Java 1.4 syntax. That is by passing an array of objects.

I have been trying to host my modules (GWT modules) into an already existing JSP page that is written in JSP 2.0 of the XML variety. I find these good because it means you are forced to create valid HTML markup. Anyways, combining the two, GWT and XML JSPs meant I was completely unable to get the GWT modules to attach and appear on the page. I was getting JavaScript Errors, j.write is not a function...

I want to use log4j in GWT application. I have dowloaded the jar file and include it in GWT project path. So I can use Logger classe to initialize a logger and use it later. But I have a error when I use it. Please, can you explain to me how to use it ? Must I insert some line in module file for specify the the presence of the log4j library ? And how can I use the property file for my logger ?

I was confronted with this problem. How to retrieve Element references the body. As GWT API doesn’t provide this service directly you need to use an other way.
