法律研究如何使用JavaFx创建标题窗格？
标题窗格只是带有标题的窗格。它包含一个或多个用户界面元素，如按钮、标签等，你可以展开和折叠它。
你可以通过实例化javafx.scene.control.TitledPane类在JavaFX中创建一个标题窗格。创建它之后，你可以使用setText()方法为窗格添加标题，并可以使用setContent()方法为其添加内容。
示例
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.TitledPane;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class TitledPaneExample extends Application {
@Override
public void start(Stage stage) {
//Creating a Button
Button button = new Button();
//Setting the title of the button
button.setText("Click Here");
//Creating the TitlePane
TitledPane pane = new TitledPane();
pane.setLayoutX(200);
pane.setLayoutY(75);
pane.setText("Sample Titled Pane");
//Setting contents to the titled pane
pane.setContent(button);
//Setting the stage
Group root = new Group(pane);
Scene scene = new Scene(root, 595, 150, Color.BEIGE);
stage.setTitle("Titled Pane Example");
stage.setScene(scene);
stage.show();
}
public static void main(String args[]){
launch(args);
}
}输出
示例
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TitledPane;
import javafx.scene.control.ToggleButton;
import javafx.scene.control.ToggleGroup;
import javafx.scene.layout.VBox;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class TiledPane2 extends Application {
@Override
public void start(Stage stage) {
//Creating toggle buttons
ToggleButton button1 = new ToggleButton("Java");
ToggleButton button2 = new ToggleButton("Python");
ToggleButton button3 = new ToggleButton("C++");
//Toggle button group
ToggleGroup group = new ToggleGroup();
button1.setToggleGroup(group);
button2.setToggleGroup(group);
button3.setToggleGroup(group);
//Adding the toggle button to the pane
VBox box = new VBox();
box.getChildren().addAll(button1, button2, button3);
//Creating the TitlePane
TitledPane pane = new TitledPane();
pane.setLayoutX(10);
pane.setLayoutY(10);
pane.setText("OpenCV Examples");
//Adding the toggle button to the pane
pane.setContent(box);
//Setting the stage
Scene scene = new Scene(pane, 595, 150, Color.BEIGE);
stage.setTitle("Titled Pane Example");
stage.setScene(scene);
stage.show();
}
public static void main(String args[]){
launch(args);
}
}输出
