继承的成员

变量

bubblesWhether this event type bubbles up in the event propagation path.
currentTarget事件的当前目标。当前路径是传播路径中目前正在为其执行事件处理程序的元素。
dispatchWhether the event is being dispatched to a visual element. An event cannot be redispatched while it being dispatched. If you need to recursively dispatch an event, it is recommended that you use a copy of the event.
flags事件的标志。
imguiEventThe IMGUIEvent at the source of this event. The source can be null since not all events are generated by IMGUI.
isDefaultPrevented如果不应为此事件执行默认操作,则返回 true。
isImmediatePropagationStoppedWhether StopImmediatePropagation() was called for this event.
isPropagationStoppedWhether StopPropagation() was called for this event.
originalMousePositionThe original mouse position of the IMGUI event, before it is transformed to the current target local coordinates.
pooledWhether the event is allocated from a pool of events.
propagationPhase当前传播阶段。
targetThe target visual element that received this event. Unlike currentTarget, this target does not change when the event is sent to other elements along the propagation path.
timestampThe time when the event was created.
tricklesDownWhether this event is sent down the event propagation path during the TrickleDown phase.
actionKeyReturns true if the platform specific action key is pressed. This key is Command on macOS and Control otherwise.
altKeyReturns true if the Alt key is pressed.
button表示按下的鼠标按钮的整数。0 为左侧,1 为右侧,2 为中间。
clickCount单击次数。
commandKeyReturns true if the Windows/Command key is pressed.
ctrlKeyReturns true if the Control key is pressed.
currentTarget事件的当前目标。当前路径是传播路径中目前正在为其执行事件处理程序的元素。
localMousePosition当前目标坐标系中的鼠标位置。
modifiersFlags holding the pressed modifier keys (Alt, Control, Shift, Windows/Command).
mouseDeltaThe difference of the mouse position between the previous mouse event and the current mouse event.
mousePosition屏幕坐标系中的鼠标位置。
shiftKeyReturns true if the Shift key is pressed.

DisposeIDisposable 实现。
GetEventTypeIdRetrieves the type id for this event instance.
PreventDefaultWhether the default actions are prevented from being executed for this event.
StopImmediatePropagationImmediately stops the propagation of the event. The event is not sent to other elements along the propagation path. This method prevents other event handlers from executing on the current target.

静态函数

RegisterEventTypeRegisters an event class to the event type system.
GetPooledGets an event from the event pool. Use this function instead of creating new events. Events obtained from this method should be released back to the pool using Dispose().
TypeIdGets the type id for the event class.
GetPooledGets an event from the event pool and initializes it with the given values. Use this function instead of creating new events. Events obtained from this method should be released back to the pool using Dispose().
