How can I loop over the controls of the scene ? I tried with getChildrenUnmodifiable() but it returns only the first level of children.
public void rec(Node node){
f(node);
if (node instanceof Parent) {
Iterator<Node> i = ((Parent) node).getChildrenUnmodifiable().iterator();
while (i.hasNext()){
this.rec(i.next());
}
}
}
Here's a modified version of amru's answer that I am using, this method gives you the components of a specific type:
private <T> List<T> getNodesOfType(Pane parent, Class<T> type) {
List<T> elements = new ArrayList<>();
for (Node node : parent.getChildren()) {
if (node instanceof Pane) {
elements.addAll(getNodesOfType((Pane) node, type));
} else if (type.isAssignableFrom(node.getClass())) {
//noinspection unchecked
elements.add((T) node);
}
}
return Collections.unmodifiableList(elements);
}
To get all components:
List<Node> nodes = getNodesOfType(pane, Node.class);
To only get buttons:
List<Button> buttons= getNodesOfType(pane, Button.class);
You need to scan recursively. For example:
private void scanInputControls(Pane parent) {
for (Node component : parent.getChildren()) {
if (component instanceof Pane) {
//if the component is a container, scan its children
scanInputControls((Pane) component);
} else if (component instanceof IInputControl) {
//if the component is an instance of IInputControl, add to list
lstInputControl.add((IInputControl) component);
}
}
}
