将调试器附加到运行中的应用程序

将调试器附加到本地或远程计算机上已运行的应用程序：

访问Debug >Start Debugging >Attach to Running Application 。
在Filter 中，输入一个字符串，按进程 ID 或名称过滤进程。
在列表中选择一个进程，然后选择Attach to Process 开始调试。

要刷新正在运行的进程列表，请选择Update List 。

要终止所选进程，请选择Kill Process 。

虽然该模式并不严格要求在Qt Creator 中打开一个项目，但打开该项目可以更方便地设置断点和步进代码。

您可以在将调试器附加到应用程序之前或之后指定断点。更多信息，请参阅设置断点。
