Support for Ext GWT (GXT)

[pczurak]

I have Eclipse 3.5 and trial version of GWT Designer and trying to use Ext GWT library.
But I can not find any documentation or examples of how to create an Ext GWT project or how to add Ext GWT controls to the Pellete.

Can someone tell me how to do either one or point me to the documentation?

Thank You

[Eric Clayberg]

Can someone tell me how to do either one or point me to the documentation?

Starting with the product docs is always a good idea...

http://download.instantiations.com/D2WB ... t/gxt.html

[pczurak]

I have added gxt.jar to my project but I do not get the GXT palette in the designer.

when I click on the Google Web Toolkit I do not get option for Ext GWT.

What am I doing wrong? I can not find any documentation about this problem.


Thank You


Peter

I have added gxt.jar to my project but I do not get the GXT palette in the designer.

Adding the gxt.jar file is only one of the required steps to adding GXT support to your project.

The Configure for using Ext GWT (GXT) command will do all the work for you.

Make sure you read the directions and right-click on your GWT Module file.

Note that the new GWT Java Project wizard also includes an option to add GXT support when a project is initially created.

[pczurak]

I do not have the "The Configure for using Ext GWT (GXT) command" it does not show up in the menu.

When I right click on the GWT Module I do not get any options for Ext GWT.

I do not have option to add GXT support to a project when it is initially created in the new GWT Java Project wizard.



How do I add the Ext GWT support to the GWT Designer? I have read and followed the directions from Ext GWT and I can create application using the Ext GWT tool kit by adding the jars manually, but GWT Designer does not recognize it.

[Eric Clayberg]

I do not have the "The Configure for using Ext GWT (GXT) command" it does not show up in the menu.

Post a screen shot of exactly what you are seeing.

Also make sure that you are using the latest GWT Designer v7.2 build.

[pczurak]

Here are the screen prints

1) shows what is installed in Eclipse
2) shows there is no option to create GWT Designer project
3) shows no optioni for Ext GWT project

[Eric Clayberg]

1) shows what is installed in Eclipse

The version/build number is truncated, so it doesn't show very much.

2) shows there is no option to create GWT Designer project

This shows that you are not following the directions (or my suggestion) to right-click on the GWT module file.

In this screen shot, you are right-clicking on the project itself.

3) shows no option for Ext GWT project

I never suggested there was an option to create a "Ext GWT Project".

There is, however, an option to create a "GWT Java Project" (as stated earlier) which includes an option to add GXT support.
