我正在使用我的新项目。现在我有这么多Jframe页面。但是我无法通过setSize方法调整框架大小。请任何人都可以帮我编码
以下代码集包含登录屏幕

public class LoginScreen extends javax.swing.JFrame {
/** Creates new form LoginScreen */
@Override
public void setSize(int width, int height) {
super.setSize(1000, 300);
}
public LoginScreen() {
initComponents();
signInBtn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String uname = usrNameTxt.getText();
char[] pword = pwordTxt.getPassword();
String password = new String(pword);
if (uname == null || uname.equals("") || uname.equals(" ") || password == null || password.equals("") || password.equals(" ")) {
Util.showErrorMessageDialog("Please fill all the fields");
}else {

我使用以下代码来设置我的jframe(检查我更新的代码开始部分)&gt;但它不起作用。
@Override
public void setSize(int width, int height) {
super.setSize(1000, 300);
}
答案 0 :(得分:4)
这里最好的解决方案可能是不随时拨打setSize(..)
,而是拨打pack()
。这将确保GUI是显示其中组件所需的最小尺寸。
答案 1 :(得分:2)
你不是在任何地方打电话给setSize()
。你要覆盖它(你不应该这样做),但你不是在呼唤它。
