GPE中包含的GWT Designer的版本是一个细微的版本不包括从Eclipse菜单中创建UI类的内容。

如果要使用此功能，则需要从此处安装完整的GWT Designer：

htt p：//dl.google.com/eclipse/inst/d2gwt/latest/4.3

请注意，我只是确认这仍然允许打开所需的UI类创建向导，但我尚未验证它与GWT 2.6配合使用。我认为它应该在GWT 2.6.1中工作，但不能保证。我已经使用GWT 2.5.1成功。

I installed a new GUI designer software, and than restarted eclipse as requested but when eclipse reopened I couldn't click the "create new visual classes" button. it's clickable but it doesn't do anything. I have to click it in order to install the toolkit and to create a new jframe.

I downloaded the GUI designer from the following link:https://developers.google.com/eclipse/docs/download

and I used the tutorial to install it in this link:http://www.***.com/watch?v=8kSjGNcKYDI

my eclipse is Kepler version.

How can I finish installing the GUI designer (and use it)

The version of the GWT Designer included in the GPE is a slimmed down version that does not include things like creating UI classes from the Eclipse menus.

If you want this functionality, you need to install the full GWT Designer from here:

http://dl.google.com/eclipse/inst/d2gwt/latest/4.3

Note that I did just verify that this still allows opening the desired UI class creation wizards, but I have not verified that it works with GWT 2.6. I think that it should work in GWT 2.6.1 but cannot guarantee that. I've used it successfully with GWT 2.5.1.
