[FIXED] How to set a values for combobox based on a clicked value from another combobox using javafx

Issue

I am new to javafx and want to set a new values for another combobox based on the selected value of the first combobox in real-time. I have tried on this code but not works

@FXML
public void A(ActionEvent event) {
String a[] = {"A","B","C"}; 
list2 = FXCollections.observableArrayList(a);
ChunitS.setItems(list2);
if (ChunitS.getValue() == (null)) {
return;
} else {
list1 = FXCollections.observableArrayList(ChunitS.getValue().toString());
ChassS.setItems(list1);
}
}

if I chose "A" in the first combobox, the second combobox should be updated to have the value "A" in it.

Solution

try to use String output = ChunitS.getSelectionModel().getSelectedItem().toString(); inside the on action first combobox function in order to get the selected. Then set the selected value in the second combobox. Hope that helps
