UnityEngine.UIElements 中的类
/
/
实现于:UnityEngine.UIElementsModule
实现接口:ITransitionEvent
过渡事件的抽象基类。
| elapsedTime | 过渡运行的秒数，不包括延迟阶段时间。 |
| stylePropertyNames | 与过渡关联的属性的名称。 |
| AffectsProperty | 确定 ITransitionEvent 是否影响指定的属性。 |
| GetPooled | 从事件池中获取一个事件，并使用给定的值对其进行初始化。使用此函数而不是创建新的事件。从此方法获取的事件应使用 Dispose() 释放回池中。 |
| bubbles | 返回此事件类型在事件传播路径中是否冒泡。 |
| currentTarget | 事件的当前目标。这是事件处理程序当前正在执行的传播路径中的 VisualElement。 |
| dispatch | 指示事件是否正在分派到可视元素。事件在分派时不能重新分派。如果您需要递归地分派事件，建议您使用事件的副本。 |
| imguiEvent | 此事件源的 IMGUIEvent。源可以为 null，因为并非所有事件都由 IMGUI 生成。 |
| isImmediatePropagationStopped | 指示是否为此事件调用了 StopImmediatePropagation()。 |
| isPropagationStopped | 是否为此事件调用了 StopPropagation()。 |
| originalMousePosition | IMGUI 事件的原始鼠标位置，在转换为当前目标本地坐标之前。 |
| pooled | 事件是否从事件池中分配。 |
| propagationPhase | 此事件的当前传播阶段。 |
| target | 接收此事件的目标可视元素。与 currentTarget 不同，此目标在事件沿传播路径发送到其他元素时不会更改。 |
| timestamp | 创建事件的时间（以毫秒为单位）。 |
| tricklesDown | 返回此事件是否在 TrickleDown 阶段沿事件传播路径向下发送。 |
| eventTypeId | 检索此事件实例的类型 ID。 |
| StopImmediatePropagation | 立即停止事件的传播。事件不会发送到传播路径中的其他元素。此方法可防止其他事件处理程序在当前目标上执行。 |
| StopPropagation | 停止传播此事件。事件不会发送到传播路径中的其他元素。此方法不会阻止其他事件处理程序在当前目标上执行。如果此方法在 TrickleDown 传播阶段期间被调用，它将阻止默认操作被处理，例如，元素由于 PointerDownEvent 而获得焦点。 |
| Dispose | IDispose 的实现。 |
| PostDispatch | 允许子类在事件分派后执行自定义逻辑。 |
| PreDispatch | 允许子类在事件分派之前执行自定义逻辑。 |
| Init | 将所有事件成员重置为其初始值。 |
| RegisterEventType | 将事件类注册到事件类型系统。 |
| GetPooled | 从事件池中获取一个事件。使用此函数而不是创建新的事件。使用此方法获取的事件需要释放回池中。您可以使用 Dispose() 释放它们。 |
| TypeId | 检索此事件实例的类型 ID。 |
