提问by skowron-line
Hi i want to set JList height as height as screen is
嗨，我想将 JList 高度设置为屏幕高度
public Locations() {
Dimension screen = Toolkit.getDefaultToolkit().getScreenSize();
screenWidth = screen.width;
screenHeight = screen.height;
initComponents();
}
private void initComponents() {
setLayout(new GroupLayout());
add(getJScrollPane0(), new Constraints(new Leading(8, 100, 10, 10), new Leading(5, 135, 10, 10)));
setSize(1366, 768);
}
private JScrollPane getJScrollPane0() {
if (jScrollPane0 == null) {
jScrollPane0 = new JScrollPane();
jScrollPane0.setSize(screenWidth, screenHeight);
jScrollPane0.setViewportView(getJList0());
}
return jScrollPane0;
}
private JList getJList0() {
if (jList0 == null) {
jList0 = new JList();
jList0.setSize(400, screenHeight);
DefaultListModel listModel = new DefaultListModel();
listModel.addElement("item0");
listModel.addElement("item1item1item1item1item1");
listModel.addElement("item2");
listModel.addElement("item3");
jList0.setModel(listModel);
}
return jList0;
}
private static void installLnF() {
try {
String lnfClassname = PREFERRED_LOOK_AND_FEEL;
if (lnfClassname == null)
lnfClassname = UIManager.getCrossPlatformLookAndFeelClassName();
UIManager.setLookAndFeel(lnfClassname);
} catch (Exception e) {
System.err.println("Cannot install " + PREFERRED_LOOK_AND_FEEL
+ " on this platform:" + e.getMessage());
}
}
/**
* Main entry of the class.
* Note: This class is only created so that you can easily preview the result at runtime.

*/
public static void main(String[] args) {
installLnF();
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setTitle("Locations");
Locations content = new Locations();
content.setPreferredSize(content.getSize());
frame.add(content, BorderLayout.CENTER);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}

但是列表大小就像我在编辑器中绘制的一样，如何更改它？

我已经通过添加解决了这个问题
add(getJScrollPane0(), new Constraints(new Leading(8, 100, 10, 10), new Leading(5, screenHeight - 115, 10, 10)));

Each List is associated with JScrollPane. So First set size of JScrollPane associated with list then set size of list with list.setsize(width,height) method
每个 List 都与 JScrollPane 相关联。所以首先设置与列表关联的 JScrollPane 的大小，然后使用 list.setsize(width,height) 方法设置列表的大小
In my program:
在我的程序中：
jScrollPane1.setSize(100,500);
list.setSize(100,500);
