我在这里要完成的一个例子是:当您打开办公室Word 2013文件并单击文件时,在左侧显示一个列表{Info,New,Open ...}。
是否有类似的JavaFX 组件?我正在寻找一种(某物)列表,其项目是垂直对齐的,你可以点击做某事(在我的情况下,改变右边的视图就像Word一样)。

您可以使用VBox和带有自定义CSS样式的按钮轻松复制Word like菜单。这是一个快速而肮脏的例子,显示了一个可能的解决方案。
public class Jfxdemos extends Application {
@Override
public void start(Stage primaryStage) {
Button btn = new Button();
btn.setText("File");
final StackPane root = new StackPane();
AnchorPane editorRoot = new AnchorPane();
editorRoot.getChildren().add(btn);
root.getChildren().add(editorRoot);
Scene scene = new Scene(root, 300, 250);
scene.getStylesheets().add("/jfxdemos/styles.css");
primaryStage.setScene(scene);
primaryStage.show();
HBox fileRoot = new HBox();
VBox menu = new VBox();
menu.setStyle("-fx-background-color: blue;");
menu.setFillWidth(true);
Button backBtn = new Button("Left Arrow");
backBtn.setPrefWidth(100);
backBtn.getStyleClass().add("custom-menu-button");
backBtn.setOnAction(new EventHandler<ActionEvent>(){
@Override
public void handle(ActionEvent event) {
FadeTransition hideFileRootTransition = new FadeTransition(Duration.millis(500), fileRoot);
hideFileRootTransition.setFromValue(1.0);
hideFileRootTransition.setToValue(0.0);
FadeTransition showEditorRootTransition = new FadeTransition(Duration.millis(500), editorRoot);
showEditorRootTransition.setFromValue(0.0);
showEditorRootTransition.setToValue(1.0);
showEditorRootTransition.play();
hideFileRootTransition.play();
root.getChildren().remove(fileRoot);
}
});
Button infoBtn = new Button("Info");
infoBtn.setPrefWidth(100);
infoBtn.getStyleClass().add("custom-menu-button");
Button newBtn = new Button("New");
newBtn.setPrefWidth(100);
newBtn.getStyleClass().add("custom-menu-button");
Button openBtn = new Button("Open");
openBtn.setPrefWidth(100);
openBtn.getStyleClass().add("custom-menu-button");
menu.getChildren().addAll(backBtn,infoBtn, newBtn, openBtn);
VBox.setVgrow(infoBtn, Priority.ALWAYS);
fileRoot.getChildren().add(menu);
btn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
root.getChildren().add(fileRoot);
FadeTransition hideEditorRootTransition = new FadeTransition(Duration.millis(500), editorRoot);
hideEditorRootTransition.setFromValue(1.0);
hideEditorRootTransition.setToValue(0.0);
FadeTransition showFileRootTransition = new FadeTransition(Duration.millis(500), fileRoot);
showFileRootTransition.setFromValue(0.0);
showFileRootTransition.setToValue(1.0);
hideEditorRootTransition.play();
showFileRootTransition.play();
}
});
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
加上styles.css。
.custom-menu-button {
-fx-background-color: blue;
-fx-text-fill: white;
-fx-border: none;
}
.custom-menu-button:hover {
-fx-background-color: lightblue;
}
单击“文件”按钮后的相同场景。我在这里使用了FadeTransition,因为它很简单。但是当然你可以尝试重现与Word中相同的动画。

以下是使用样式MenuButton
的快速示例。
import java.util.stream.Collectors;
import java.util.stream.Stream;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.MenuButton;
import javafx.scene.control.MenuItem;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class WordLikeMenuButton extends Application {
@Override
public void start(Stage primaryStage) {
MenuButton menuButton = new MenuButton();
menuButton.getItems().addAll(
Stream.of("Info", "New", "Open", "Save", "Save As", "Print", "Share", "Export", "Close")
.map(MenuItem::new).collect(Collectors.toList()));
BorderPane root = new BorderPane(null, menuButton, null, null, null);
Scene scene = new Scene(root, 350, 75);
scene.getStylesheets().add("word-like-menu-button.css");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
字状菜单-button.css:
.menu-button, .menu-button .menu-item, .menu-button .context-menu {
-fx-background-color: #28559c;
}
.menu-button .menu-item:hover {
-fx-background-color: #3b6bb7 ;
}
.menu-button .menu-item .label {
-fx-text-fill: white ;
}
.menu-button > .arrow-button {
-fx-background-color: white, #28559c ;
-fx-background-insets: 1, 3 ;
-fx-background-radius: 16, 16 ;
-fx-padding: 8 ;
}
.menu-button > .arrow-button > .arrow {
-fx-background-color: white ;
/*-fx-background-insets: 0, 2 ;
-fx-background-radius: 12, 12 ;*/
-fx-padding: 8 ;
-fx-shape: "M0 6 l-6 -6 l0 -2 l6 -6 l2 0 l-6 6 l12 0 l0 2 l-12 0 l6 6 z";
}

使用JFXTabPane
并稍微自定义它会好得多。对于后退箭头,您可以执行本教程http://synappse.co/blog/vertical-stateful-jfxtabpane-with-icons-in-javafx/
