There’s a workaround: define a new Dummy class with member fields of all the types that you want to be included in serialization. Then add a method to your RPC interface: Dummy dummy(Dummy d); The implementation is just this: Dummy dummy(Dummy d) { return d; } And the async interface will have this: void dummy(Dummy … Read more
If you add “myImage” as style name to any widget, it will set those widgets’ background…
Trade-offs Let’s start with all the trade-offs I can come up with: you’re using Java – it means that your webdevs’ proficiency in javascript won’t come in handy as much (it will be helpful if you dabble in JSNI) problems with indexing by search engines – IMHO, this should be the biggest disadvantage of using … Read more
I’m only mildly familiar with Flex, but have worked with GWT for many years. We had to make a very similar decision some years ago (Flash vs GWT), but for different reasons. In the end we saw the many advantages of GWT over Flash (Many of which apply to Flex): Not all our customers have … Read more
I wrote two classes that solve this problem on my project. Basically, each individual callback registers with a parent. The parent waits for each child callback to complete, then fires off it’s own handleSuccess(). The client code looks like this: public void someGwtClientSideMethod() { SomeServiceAsync someService = GWT.create(SomeService.class); ParallelCallback fooCallback = new ParallelCallback(); ParallelCallback barCallback … Read more
See the official page on GWT date and number formatting. They suggest the following: myNum decimal = 33.23232; myString = NumberFormat.getFormat(“#.00”).format(decimal); It is best to use their supported, optimized methods, than to cook up your own non-optimal method. Their compiler will be optimizing them all to nearly the same thing anyway in the end.
var a=”1,125″; a=a.replace(/\,/g,”); // 1125, but a string, so convert it to number a=parseInt(a,10); Hope it helps.
did you check http://code.google.com/webtoolkit/doc/latest/tutorial/RPC.html#serialize the article says: It has a default (zero argument) constructor with any access modifier (e.g. private Foo(){} will work) I’m allways forgetting zeroargument const. when I am making a serializable object 😀
Here are some more details on how to accomplish this with the (currently latest) 19.0 release of Guava. The Guava release consists of two JARs, guava-19.0.jar and guava-gwt-19.0.jar. You will need both for getting Guava to work within your GWT project. (In a non-GWT project you will only need the former.) Download them and add … Read more
Thanks for all the responses. Zakness came the closest to giving me the answer I needed, however, I came up with a slightly simpler model. My main goal was to avoid using a static variable to my main data structure. I also hit the problem of trying to figure out if that main data structure … Read more
