不支持包装其Menu
s.
可以有不同的方法来实现您想要的布局。其中之一在下面。
要将第二个管理 flowPane 向右对齐,请使用HBox.setHgrow
flowPane。要在 flowPane 中对齐菜单栏,请使用flow.setAlignment(Pos.TOP_RIGHT)
:
@Override
public void start(Stage primaryStage) {
final Menu menu01 = new Menu("App Menu 1");
final Menu menu02 = new Menu("App Menu 2");
final Menu menu1 = new Menu("Admin Menu 1");
final Menu menu2 = new Menu("Admin Menu 2");
final Menu menu3 = new Menu("Admin Menu 3");
MenuBar menuBar0 = new MenuBar();
menuBar0.getMenus().addAll(menu01, menu02);
menuBar0.setMinWidth(220); // do not shrink
MenuBar menuBar1 = new MenuBar();
menuBar1.getMenus().addAll(menu1);
MenuBar menuBar2 = new MenuBar();
menuBar2.getMenus().addAll(menu2);
MenuBar menuBar3 = new MenuBar();
menuBar3.getMenus().addAll(menu3);
FlowPane flow = new FlowPane(Orientation.HORIZONTAL);
// flow.setStyle("-fx-background-color: gray; -fx-border-color: red"); // visual debug
flow.setAlignment(Pos.TOP_RIGHT);
flow.setHgap(0);
flow.getChildren().addAll(menuBar1, menuBar2, menuBar3);
TextField searchField = new TextField();
searchField.setPromptText("Search here..");
// make it unresizable
searchField.setMinWidth(200);
searchField.setMaxWidth(200);
HBox mainBox = new HBox(5);
mainBox.setAlignment(Pos.CENTER_LEFT);
HBox.setHgrow(flow, Priority.ALWAYS);
mainBox.getChildren().addAll(menuBar0, searchField, flow);
mainBox.setStyle("-fx-background-color: lightgray;");
VBox vBox = new VBox(0);
vBox.getChildren().addAll(mainBox, new Button("Demo"));
Scene scene = new Scene(vBox);
primaryStage.setScene(scene);
primaryStage.show();
}
