您遇到的主要问题是默认布局管理器的布局设置为FlowLayout
,这意味着JScrollPane
将要使用它的首选尺寸进行布局,这样可能无法填满整个面板.
The primary problem you're having is the fact that the default layout manager's layout is set to FlowLayout
, which means that the JScrollPane
will want to use it's preferred size to be layout with, which may not fill the entire panel.
相反,请使用BorderLayout
final JPanel info = new JPanel(new BorderLayout()); // <-- Change me :D
final JScrollPane infoS = new JScrollPane(info,ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED,ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED);
// These are bad ideas, setLocation and setSize won't work, as the panel should be
// under the control of a layout manager
//info.setLocation(10,78);
//info.setSize(420,490);
//infoS.setPreferredSize(new Dimension(600, 600));
gui.add(infoS);
