如何在SuggestBox中显示所有可能的值

Question

我想在SuggestBox中显示所有可能的值.

当然,我有以下代码(settingName是一个SuggestBox)

settingName.getTextBox().addFocusHandler(new FocusHandler() {
    @Override
    public void onFocus(FocusEvent event) {
      settingName.showSuggestionList();
    }
  });

不幸的是,建议箱显示任何内容.当然,settingName与oracle相关联,其中包含多个值.

我疯了吗 ？

根据文件:

public void showSuggestionList()

Show the current list of suggestions.

Answer 1

您需要设置默认值以显示 suggestOracle.setDefaultSuggestionsFromText(..)
