我有一个 VBox 的根节点。我还有一个使用窗格和按钮创建的复合节点。复合节点的多个实例被添加到 VBox。我试图找到一种在触发内部按钮时删除每个复合节点的方法。但我没能找到方法。这是我的代码,有人可以帮我吗?
@Override
public void start(Stage primaryStage) {
VBox root = new VBox();
root.setAlignment(Pos.TOP_CENTER);
root.setSpacing(10);
Scene scene = new Scene(root, 300, 700);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
// 10 Non reffered instances will be added to the VBox(root)
for (int i=0; i<10; i++) {
Pane compositeChild = new Pane();
compositeChild.setPrefWidth(300);
compositeChild.setPrefHeight(40);
compositeChild.setBorder(new Border(new BorderStroke(Color.CORAL, BorderStrokeStyle.SOLID, CornerRadii.EMPTY, BorderWidths.DEFAULT)));
Button btn = new Button("Delete Me");
btn.setPrefWidth(200);
btn.setPrefHeight(30);
btn.setLayoutX(50);
btn.setLayoutY(5);
// I want to find some code for below action event
btn.setOnAction(e2 -> {
//how can I remove only one compositeChild that the event fired From the root(VBox)
((Button)e2.getSource()).setText("I should be deleted??");
});
compositeChild.getChildren().add(btn);
root.getChildren().add(compositeChild);
}
}
