DataGroup 类是数据项目的容器基类。DataGroup 类将数据项目转换为可视元素以进行显示。尽管此容器可以包含可视元素,但它通常仅用于包含作为子项的数据项目。 DataGroup 类充当子数据项目或实现 IVisualElement 接口且为 DisplayObject 的可视元素。数据项目可以是诸如 String 和 Number 对象等的简单数据项目,也可以是诸如...
就是将第三个参数改为false , 则结果为:单击A有反应 addEventListener的第三个参数如果为false(默认为flase), 回调事件会在冒泡状态的时候执行 ;否则会在目标状态执行。当参数为true时 ,在A上注册,不存在冒泡状态 , 回掉函数不会执行。 事件机制的3个阶段 Event有一个属性:eventPhase,可以为以下3个值: 捕获阶...

New data structure:namedarraytuple Rlpyt introduces new object classesnamedarraytuplefor easier organization of collections of numpy arrays / torch tensors. (seerlpyt/utils/collections.py). Anamedarraytupleis essentially anamedtuplewhich exposes indexed or sliced read/writes into the structure. For exa...
First, create descriptions for your rendering resources (e.g. buffers, textures) and declare them as framegraph resources. struct buffer_description { std::size_t size; }; struct texture_description { std::size_t levels; GLenum format; std::array<std::size_t, 3> size ; }; using buffer...
