I am a beginner messing around with JavaFX. In my program, when a checkbox is selected I want it to display a label along with a ChoiceBox. However, when it is unselected, I want both of these to disappear. I'm not quite sure how to do this however.
Here is my code:
String [] options = new String [] {"A", "B", "C", "D", "E", "F"};
CheckBox [] cbs = new CheckBox[options.length];
for (int i = 0; i < options.length; i++){
final CheckBox cb = cbs[i] = new CheckBox(options[i]);
cb.selectedProperty().addListener(new ChangeListener<Boolean>() {
@Override
public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
if(observable.getValue() == true){
ChoiceBox<Integer> choice = new ChoiceBox<>();
Label label = new Label("How many of the selected accounts do you have?");
choice.getItems().addAll(1, 2, 3, 4, 5);
choice.setValue(1);
selection.setAlignment(Pos.BOTTOM_LEFT);
selection.getChildren().addAll(label, choice);
gp.add(selection, 0, 8);
} else if (observable.getValue() == false){
// remove above block if getValue() == false;
}
}
});
}
