keywords: [UE4]Viewport Resized Event(视图窗口的尺寸修改变化时的回调事件)

keywords: Viewport, Resize, Callback, Event

1,在BeginPlay()函数中添加绑定事件:

GEngine->GameViewport->Viewport->ViewportResizedEvent.AddUObject(this, &MyObj::MyFunction);

2,编写回调逻辑。注意,回调函数必须包含FViewport*和uint32两个参数

void MyObj::MyFunction(FViewport* ViewPort, uint32 val)
{
}
