java - 对齐两个 Javafx GridPane

Question

我创建了两个 Javafx Gridpane，我希望它们位于同一行，第二个网格 Pane 必须位于第一个网格 Pane 旁边的同一行。因为我运行的时候会碰到另一只。这是我的代码:

Group root = new Group();
    Scene scene = new Scene(root);

    //creation du layout
    layout = new GridPane();
    layout.getColumnConstraints().add(new ColumnConstraints(350)); // column 1 is 350 wide
    layout.getColumnConstraints().add(new ColumnConstraints(350)); 
    layout.getColumnConstraints().add(new ColumnConstraints(350)); 
    layout.setGridLinesVisible(true);

     final Label  source = new Label ("DRAG ");
    layout.add(source, 0, 0);


     final Label  target = new Label ("DROP ");
    layout.add(target, 1, 0);

    layout2 = new GridPane();
    layout2.getColumnConstraints().add(new ColumnConstraints(20)); // column 1 is 20 wide

    layout2.setGridLinesVisible(true);

    final Label  source1 = new Label ("fire");
    layout2.add(source1, 0, 4);
    root.getChildren().addAll(layout,layout2);

Answer 1

如果您想将它们相邻添加，最好的选择是使用 HBox布局:

HBox hBox = new HBox();
//hBox.setSpacing(5.0); 
//hBox.setPadding(new Insets(5,5,5,5));
hBox.getChildren().addAll(layout, layout2);
