Answer 1

检查您的*.gwt.xml文件并在下面删除所有这些

<set-property name="user.agent" value="..anything.." />

将以下行添加到project_name.gwt.xml

<set-property name="user.agent" value="ie6" />

然后尝试使用Internet Explorer而不是Firefox等。

如果仍然不起作用，请尝试此代码;

com.google.gwt.user.client.ui.Label = new com.google.gwt.user.client.ui.Label("asdasd");
        l.addClickHandler(new ClickHandler() {

            @Override
            public void onClick(ClickEvent event) {
                // TODO Auto-generated method stub
                MessageBox.info("", "asd", null);
            }
        });

Answer 2

您可以尝试使用HTML而不是Label。实际上，如果你想要一个“可点击”的组件，带有超链接或锚点或超链接的Button或HTML会更有意义，因为它们对用户来说更直观。
