How can i add scroll!??? Please Click to show pic
when i put ScrollPane in myCode,unfortunatly dose not have good performance and myscroll dosnt cover all my Line
this Code is Below
package schedul;
import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.control.ScrollPane;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.HBox;
import javafx.scene.shape.Circle;
import javafx.scene.shape.Line;
import javafx.scene.text.Text;
import javafx.stage.Stage;
public class scene11 extends Application {
#Override
public void start(Stage primaryStage) throws IOException {
AnchorPane root=FXMLLoader.
<AnchorPane>load(getClass().getResource("/schedul/scene1.fxml"));
Line line=new Line();
Text text=new Text();
line.setStartX(50);
line.setStartY(50);
line.setEndX(800);
line.setEndY(50);
root.getChildren().add(line);
HBox content = new HBox(root);
ScrollPane scroller = new ScrollPane(content);
scroller.setFitToWidth(true);
Scene scene= new Scene(new BorderPane(scroller, null, null, null,
null));
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
I expected the scroll to be created automatically

I took your sample code and removed the irrelevant bits.
All you need to do to make an AnchorPane scrollable is put it in a ScrollPane. This is demonstrated by the sample below. The same will work for any other Pane type.
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.ScrollPane;
import javafx.scene.layout.AnchorPane;
import javafx.scene.shape.Line;
import javafx.stage.Stage;
public class ScrollApp extends Application {
#Override
public void start(Stage stage) {
stage.setScene(
new Scene(
new ScrollPane(
new AnchorPane(
new Line(50, 50, 800, 50)
)
)
)
);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
After the application launches, by default, it will size to fit all of the content, so you won't see the scroll bars. If you make the window smaller horizontally, you will see the horizontal scrollbar, and similarly for the vertical direction.
