如何使 JPanel 可滚动?当我将它添加到包含面板时,我实现了可滚动界面
tabbedPane.add("Editor", new JScrollPane(storeyEditor = new MNScrollablePanel()));
没有任何作用
代码:
public class MNScrollablePanel extends JPanel implements Scrollable {
public Dimension getPreferredScrollableViewportSize() {
return getPreferredSize();
}
public int getScrollableBlockIncrement(Rectangle visibleRect, int orientation, int direction) {
return 10;
}
public boolean getScrollableTracksViewportHeight() {
return false;
}
public boolean getScrollableTracksViewportWidth() {
return false;
}
public int getScrollableUnitIncrement(Rectangle visibleRect, int orientation, int direction) {
return 10;
}
}
