英文:
Retrieving array object inside a ComboBox object
问题
public class AddressSelector {
private String name;
private AddressInternalType[] types;
}
private ComboBox<AddressSelector> lvlTwoDen;
lvlTwoDen.valueProperty().addListener((observable, oldValue, newValue) -> {
AddressItemExt address = lvlOneAddress.getValue();
if(address != null){
setupLvlTwoName(ServiceUtil.getAddress(address.getCode(), lvlTwoAddress.getEditor().getText() + "*", lvlTwoDen.getValue().getTypes()));
}
});
I have a comboBox of a specific object. In that comboBox object I have an array object which I want to retrieve. I tried the following code snippet using `lvlTwoDen.getValue().getTypes()` however `lvlTwoDen.getValue()` returns null. How can I retrieve the Types from the combobox?
EDIT:
I have 2 comboboxes. lvlOneDen and lvlTwoDen. On selection of a value from lvlOneDen, I am setting a value in lvlTwoDen successfully using `lvlTwoDen.getSelectionModel().select(0)`.
like this:
lvlOneSiruta.valueProperty().addListener((observable, oldVal, newVal) -> {
lvlTwoDenom.getSelectionModel().select(0);
});
However, since I've just selected the value in lvlOneDen and haven't clicked and selected any value in lvlTwoDen, I get lvlTwoDen.getValue() as null. Is there a way to set a 'value' for lvlTwoDen on selection of a value in lvlOneDen?
