我有一个正在为游戏创建的安装程序，到目前为止有两个按钮。一个下载游戏，如果检测到可执行文件，则启动游戏。我对两个按钮都进行了多线程处理，因此单击任何一个按钮时，GUI都不会冻结。问题是，如果我单击其中一个按钮，则另一个按钮将无法工作，直到重新启动应用程序。我需要某种方法使线程在其处理完成后关闭，以便打开线程以使其他按钮起作用。
这是我到目前为止所拥有的：

您的问题是由//creating custom annotation
import javax.validation.Constraint;
import javax.validation.Payload;
import java.lang.annotation.*;
@Retention(RetentionPolicy.RUNTIME)
@Inherited
@Target({ElementType.METHOD,ElementType.FIELD})
@Documented
@Constraint(validatedBy = Mobile_EmailValidation.class)
public @interface CustomAnnotation {
String message() /*default "Invalid phone number"*/;
int min();
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
// for validation class
public class Mobile_EmailValidation implements ConstraintValidator<CustomAnnotation, String> {
static{
System.out.println("hi this is static block");
}
@Override
public void initialize(CustomAnnotation constraintAnnotation) {
System.out.println("hi this annotation works");
}
@Override
public boolean isValid(String contactField,
ConstraintValidatorContext ctx) {
System.out.println("hi this annotation works");
if (contactField == null)
return true;
boolean isValid;
if (contactField.length()<10) {
isValid = false;
}
else {
isValid = true;
}}
//this is my entity class
@Entity
@Table(name = "user")
public class User extends BaseDomain {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column(name = "name", nullable = true, length = 40)
private String name;
@CustomAnnotation(message = "invalid messages",min=4)
@Column(name = "email_id", unique = true, nullable = false, length = 100)
private String emailId;
有一个值引起的。
您需要重置self.worker。
在下面，我已经调整了您的代码以执行此操作，在此过程中，我将self.worker重命名为notify_window，这仅仅是因为它使进行的操作更加明显并符合python标准。我确信还有很多其他方法可以实现这一目标，在这种情况下，这仅仅是一种简单的实现方法。
