Question

我现在正在使用GWT 2.5.1，我想将我的SDK版本更改为2.7.0。我手动下载了最新的SDK并更改了项目属性中的SDK设置。编译器此时抛出的错误是：

跟踪的第二行指向TextButton类对象声明，该声明是根据gwt 2.5.1包结构从com.google.gwt.widget.client包导入的。但我无法在gwt 2.7.0中找到任何类似的类。我该如何解决这个问题？

Answer 1

用Button类替换TextButton用法。它有一个构造函数，可以将String或SafeHtml显示为文本。如果您愿意，可以稍后对其应用不同的样式。

/**
   * Creates a button with the given HTML caption.
   *
   * @param html the HTML caption
   */
  public Button(SafeHtml html) {
    this(html.asString());
  }

  /**
   * Creates a button with the given HTML caption.
   *
   * @param html the HTML caption
   */
  public Button(String html) {
    this();
    setHTML(html);
  }

如何将项目从gwt 2.5.1升级到gwt 2.7.0？
