A）固定內容大小

內容的大小將與其 ScrollPane 容器的大小相同。

import javafx.scene.control.ScrollPane;   //Import the ScrollPane
import javafx.scene.control.ScrollPane.ScrollBarPolicy; //Import the ScrollBarPolicy
import javafx.scene.layout.Pane;

ScrollPane scrollpane;
Pane content = new Pane();  //We will use this Pane as a content

scrollpane = new ScrollPane(content);  //Initialize and add content as a parameter
scrollpane.setPrefSize(300, 300);   //Initialize the size of the ScrollPane

scrollpane.setFitToWidth(true);  //Adapt the content to the width of ScrollPane
scrollpane.setFitToHeight(true); //Adapt the content to the height of ScrollPane

scrollpane.setHbarPolicy(ScrollBarPolicy.ALWAYS);  //Control the visibility of the Horizontal ScrollBar
scrollpane.setVbarPolicy(ScrollBarPolicy.NEVER);  //Control the visibility of the Vertical ScrollBar
//There are three types of visibility (ALWAYS/AS_NEEDED/NEVER)
