有没有可以用来实现此目的的示例?
Is there any example which I can use to see how to implement this?
推荐答案
制表符与JavaFX中的许多其他元素一样,具有称为setGraphic(Node value)
的方法,您可以在其中放置任何JavaFX节点.示例:
Tabs, like many other elements in JavaFX, have a method called setGraphic(Node value)
, in which you can put any JavaFX node. Example:
import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.Tab;
import javafx.scene.control.TabPane;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.HBox;
import javafx.scene.paint.Color;
import javafx.scene.shape.Circle;
import javafx.stage.Stage;
public class TabPaneTest extends Application {
public static void main(String[] args) {
Application.launch(args);
}
@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("Tabs");
Group root = new Group();
Scene scene = new Scene(root, 400, 250, Color.WHITE);
TabPane tabPane = new TabPane();
BorderPane borderPane = new BorderPane();
for (int i = 0; i < 5; i++) {
Tab tab = new Tab();
tab.setGraphic(new Circle(0, 0, 10));
HBox hbox = new HBox();
hbox.getChildren().add(new Label("Tab" + i));
hbox.setAlignment(Pos.CENTER);
tab.setContent(hbox);
tabPane.getTabs().add(tab);
}
// bind to take available space
borderPane.prefHeightProperty().bind(scene.heightProperty());
borderPane.prefWidthProperty().bind(scene.widthProperty());
borderPane.setCenter(tabPane);
root.getChildren().add(borderPane);
primaryStage.setScene(scene);
primaryStage.show();
}
}
结果:
