你可以打电话getDividers().get(0)
来获得第一个分频器。它有一个positionProperty()
您可以使用时间线制作动画的:

import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.beans.property.BooleanProperty;

import javafx.util.Duration;
public class AnimatedSplitPane extends Application {
@Override
public void start(Stage primaryStage) {
SplitPane splitPane = new SplitPane(new Pane(), new Pane());
splitPane.setDividerPositions(0);
BooleanProperty collapsed = new SimpleBooleanProperty();
collapsed.bind(splitPane.getDividers().get(0).positionProperty().isEqualTo(0, 0.01));
Button button = new Button();
button.textProperty().bind(Bindings.when(collapsed).then("Expand").otherwise("Collapse"));
button.setOnAction(e -> {
double target = collapsed.get() ? 0.2 : 0.0 ;
KeyValue keyValue = new KeyValue(splitPane.getDividers().get(0).positionProperty(), target);
Timeline timeline = new Timeline(new KeyFrame(Duration.millis(500), keyValue));
timeline.play();
});
HBox controls = new HBox(button);
controls.setAlignment(Pos.CENTER);
controls.setPadding(new Insets(5));
BorderPane root = new BorderPane(splitPane);
root.setBottom(controls);
Scene scene = new Scene(root, 600, 600);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
