成员类型文档
enum QPlatformSurfaceEvent::SurfaceEventType
此枚举描述了平台表面事件的类型。可能的类型包括：
| 常量 | 值 | 描述 |
|---|---|---|
QPlatformSurfaceEvent::SurfaceCreated | 0 | 底层本机画布已创建 |
QPlatformSurfaceEvent::SurfaceAboutToBeDestroyed | 1 | 底层本机表面将在该事件发生后立即被销毁 |
SurfaceAboutToBeDestroyed 事件类型可用于在平台窗口被销毁之前停止对其的渲染。
成员函数文档
[explicit] QPlatformSurfaceEvent::QPlatformSurfaceEvent(QPlatformSurfaceEvent::SurfaceEventType surfaceEventType)
为给定的surfaceEventType 构建一个平台表面事件。
[protected delete] QPlatformSurfaceEvent::QPlatformSurfaceEvent(QPlatformSurfaceEvent &&)
通过移动构造一个QPlatformSurfaceEvent 实例。该函数已被删除。
QPlatformSurfaceEvent::SurfaceEventType QPlatformSurfaceEvent::surfaceEventType() const
返回平台表面事件的具体类型。
[protected delete] QPlatformSurfaceEvent &QPlatformSurfaceEvent::operator=(QPlatformSurfaceEvent &&)
将other 按移动赋值方式赋值给此QPlatformSurfaceEvent 实例。该函数已被删除。
[noexcept protected default] QPlatformSurfaceEvent &QPlatformSurfaceEvent::operator=(const QPlatformSurfaceEvent &other)
将 `other ` 复制并赋值给此 `QPlatformSurfaceEvent ` 实例。
