C++ windows窗体应用程序的InitializeComponent()函数

Dee1997 2017-06-15 04:12:01
调试的时候发现程序走完InitializeComponent() 之后并没有回到调用的地方而是跳到了formsizechange函数的地方

然后看堆栈的顺序好像是system导致了窗体的变化然后调用了formsizechange函数
看不懂。。。。

有好心人可以解释一下吗~

formsizechange 在最后面


没有回到这里



从这里跳出

调用的堆栈:
YOLO系列是基于深度学习的端到端实时目标检测方法。 PyTorch版的YOLOv5轻量而高性能,更加灵活和易用,当前非常流行。 本课程将手把手地教大家使用labelImg标注和使用YOLOv5训练自己的数据集。课程实战分为两个项目:单目标检测(足球目标检测)和多目标检测(足球和梅西同时检测)。  本课程的YOLOv5使用ultralytics/yolov5,在Windows和Ubuntu系统上分别做项目演示。包括:安装YOLOv5、标注自己的数据集、准备自己的数据集(自动划分训练集和验证集)、修改配置文件、使用wandb训练可视化工具、训练自己的数据集、测试训练出的网络模型和性能统计。 除本课程《YOLOv5实战训练自己的数据集(Windows和Ubuntu演示)》外,本人推出了有关YOLOv5目标检测的系列课程。请持续关注该系列的其它视频课程,包括:《YOLOv5(PyTorch)目标检测:原理与源码解析》课程链接:https://edu.csdn.net/course/detail/31428《YOLOv5目标检测实战:Flask Web部署》课程链接:https://edu.csdn.net/course/detail/31087《YOLOv5(PyTorch)目标检测实战:TensorRT加速部署》课程链接:https://edu.csdn.net/course/detail/32303《YOLOv5目标检测实战:Jetson Nano部署》课程链接:https://edu.csdn.net/course/detail/32451《YOLOv5+DeepSORT多目标跟踪与计数精讲》课程链接:https://edu.csdn.net/course/detail/32669《YOLOv5实战口罩佩戴检测》课程链接:https://edu.csdn.net/course/detail/32744《YOLOv5实战中国交通标志识别》课程链接:https://edu.csdn.net/course/detail/35209 《YOLOv5实战垃圾分类目标检测》课程链接:https://edu.csdn.net/course/detail/35284
