New user, Eclipse, GWT. How do I find these widgets in my Eclipse project?

I also am using Instantiations Designer, which is very nice, but I sure would like to use the widgets shown here.

There must be a simple way to do this but so far all I have a is a long list of things that don't work.

Thank you.

There is no one who can write a decent and easy tutorial !!!. I tried to make a "hallo world" more than 5 times using differents tutorials and i can't make it run!!!

How can i bought a tool like this? I can't eather start a simple project!

With extjs i run a grid sample in seconds! That is a shame!

What sort of problems are you running into? What errors are you seeing?

the problem is that i don't see anything... i use the cypal plugin for eclipse, to help build a start application, but i load all, got no errors, and in the mini google's browser i cant see nothing.

The alert function works ...

Is very strange, because i get a sample from ext page.


thanks

I'm assuming you are using GWT's hosted mode when you say the mini google browser. If so, there should be another window that pops up when you run your application titled 'Google Web Toolkit Development Shell'. Is there any output in this window?

[dpope22]

Can you post the code you are trying to run?

This sample refers to another RIA library, not GXT. They have similar names and it can be confusing at first, but I'm pretty sure that the two aren't compatible. You'll either have to use GXT (Ext-GWT) or GWT-EXT. The pure Java solution is GXT.

Interesting. Do you know a working tutorial for GXT?

[dpope22]

Try to get up and running with just GWT first. Here's their getting started guide:
http://code.google.com/webtoolkit/gettingstarted.html

Once you get that working, you can add in GXT to the mix.

no erros only blank screen:

public class TestGXTApp extends LayoutContainer {
public void onModuleLoad()
{
TestGXTApp hello = new TestGXTApp();
RootPanel.get().add( hello );
}
}

Looks like an infinite loop if onModuleLoad() is called when the class is constructed. Either way, your class doesnt have anything in it. TextGXTApp is an empty class (no widgets in it, nothing to display)

Change the TestGXTApp class to HelloWorldExample.

[Arno.Nyhm]

your GxtApp need to include a different entrypoint, otherwise the app did not start.
in your onModuleLoad you need to use the HelloWorldExample

and not your GxtApp


next thing: i dont know if its ok. but i see you start the AppEngine Server - but you point to localhost:8080 - i dont test the appengine stuff but this can also be a point. if you run it localy then the message should be an other:
http://code.google.com/intl/de-DE/appengine/docs/java/tools/eclipse.html#Running_the_Project


PS: and i would place the window in HelloWorldExample into a MyWindow extends window - so you can dive it better if you have more then one window.

Thanks i wil try and i will post soon :D
