Process Explorer使用示例

Process Explorer 是一款 Windows 系统下的进程管理工具，可以查看系统中正在运行的进程、线程、模块、句柄等信息。使用时，可以先下载安装 Process Explorer，然后打开程序，就可以看到系统中所有的进程信息。可以通过双击进程来查看该进程的详细信息，也可以通过右键菜单来进行进程的操作，如结束进程、暂停进程等。同时，Process Explorer 还可以显示进程之间的关系，帮助用户更好地了解系统的运行情况。

3. 修改 activiti-explorer.war 文件下 WEB-INF/classes 目录下的 db.properties 文件，将其中的数据库配置改为：

db=mysql
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/activiti?useSSL=false&useUnicode=true&characterEncoding=utf-8&autoReconnect=true
jdbc.username=root
jdbc.password=root

其中，jdbc.url 中的数据库名应改为自己创建的数据库名称，jdbc.username 和 jdbc.password 应改为自己的数据库用户名和密码。

4. 启动 Tomcat 服务器，访问 http://localhost:8080/activiti-explorer 即可使用 activiti-explorer 示例工程。

QProcess: Destroyed while process ("explorer.exe") is still running

这个错误通常表示在 QProcess 对象销毁时，相关的进程仍然在运行。这可能是因为你在销毁 QProcess 对象之前忘记了终止或等待相关的进程。

要解决这个问题，你可以在销毁 QProcess 对象之前，确保先调用其 `terminate()` 方法终止相关的进程。然后，使用 `waitForFinished()` 方法等待进程的完成。

以下是一个示例代码片段，展示了如何正确处理 QProcess 对象的销毁和进程的终止：

QProcess process;
process.start("explorer.exe");

// ...

// 在销毁 QProcess 对象之前，先终止相关的进程
process.terminate();
process.waitForFinished();

// 销毁 QProcess 对象
process.deleteLater();

通过这种方式，你可以确保在销毁 QProcess 对象时，相关的进程已经被正确终止和等待完成，避免出现该错误。
