如何在 SuggestBox 中显示所有可能的值
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，建议框显示任何内容。当然，settingName 与一个预言机相关联，其中包含多个值。
我疯了吗？
根据文档：
公共无效showSuggestionList()
显示当前的建议列表。
I would like to display all possible values in a SuggestBox.
Naturally, I have the following code (settingName is a SuggestBox)
settingName.getTextBox().addFocusHandler(new FocusHandler() {
@Override
public void onFocus(FocusEvent event) {
settingName.showSuggestionList();
}
});
Unfortunately, the suggestbox displays anything. Of course, the settingName is associated to an oracle with several values inside it.
Am I crazy ?
According to the documentation :
public void showSuggestionList()
Show the current list of suggestions.

您需要将默认值设置为
suggestOracle.setDefaultSuggestionsFromText(..)You need to set the defaults to show by
suggestOracle.setDefaultSuggestionsFromText(..)显示列表时，
SuggestBox将向预言机询问要显示的值。如果文本框为空，则将调用requestDefaultSuggestions（默认情况下调用requestSuggestions）。When showing the list, the
SuggestBoxwill ask the oracle for values to show. If the text box is empty, thenrequestDefaultSuggestionswill be called (which by default callsrequestSuggestions).
