我有一个ComboBox
由国家组成的 [JavaFX]。
我的对象:
public static class CountryObj {
private String TCountryDescr;
private String TCountryCode;
private CountryObj(String CountryDescr,String CountryCode) {
this.TCountryDescr = CountryDescr;
this.TCountryCode = CountryCode;
}
public String getTCountryCode() {
return TCountryCode;
}
public void setTCountryCode(String fComp) {
TCountryCode= fComp;
}
public String getTCountryDescr() {
return TCountryDescr;
}
public void setCountryDescr(String fdescr) {
TCountryDescr = fdescr;
}
@Override
public String toString() {
return TCountryDescr;
}
}
然后我有我的ObservableList
:
private final ObservableList<CountryObj> CountrycomboList =
FXCollections.observableArrayList(
new CountryObj("United States", "US"),
new CountryObj("United Kingdom", "UK"),
new CountryObj("France", "FR"),
new CountryObj("Germany", "DE"));
然后我的ComboBox
哪个显示国家的名字和国家的代码是我自己用的:
private ComboBox<CountryObj> cCountry1 = new ComboBox<>();
cbCountry1.setItems(CountrycomboList);
cbCountry1.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<CountryObj>() {
@Override
public void changed(ObservableValue<? extends CountryObj> arg0, CountryObj arg1, CountryObj arg2) {
if (arg2 != null) {
System.out.println("Selected Country: " + arg2.getTCountryCode());
}
}
});
如果我只有国家代码“DE”,我如何自动选择一个国家,例如德国?
