class in UnityEngine.UIElements

Inherits from:UIElements.EventBase_1
/
Implemented in:UnityEngine.UIElementsModule
Implements interfaces:IKeyboardEvent
This is the base class for keyboard events.
The typical keyboard event loop is as follows:
- When a key is pressed, a KeyDownEvent is sent.
- If the key is held down for a duration determined by the OS, another KeyDownEvent with the same data is
sent. While the key is held down, the event is sent repeatedly at a frequency determined by the OS.
- When the key is released, a KeyUpEvent is sent.
By default, keyboard events trickle down and bubble up. They are cancellable, and disabled elements won't
receive these events.
| actionKey | Gets a boolean value that indicates whether the platform-specific action key is pressed. True means the action key is pressed. False means it isn't. |
| altKey | Gets a boolean value that indicates whether the Alt key is pressed. True means the Alt key is pressed. False means it isn't. |
| character | Gets the character entered. |
| commandKey | Gets a boolean value that indicates whether the Windows/Cmd key is pressed. True means the Windows/Cmd key is pressed. False means it isn't. |
| ctrlKey | Gets a boolean value that indicates whether the Ctrl key is pressed. True means the Ctrl key is pressed. False means it isn't. |
| keyCode | The key code. |
| modifiers | Gets flags that indicate whether modifier keys (Alt, Ctrl, Shift, Windows/Cmd) are pressed. |
| shiftKey | Gets a boolean value that indicates whether the Shift key is pressed. True means the Shift key is pressed. False means it isn't. |
| Init | Resets the event members to their initial values. |
| GetPooled | Gets a keyboard event from the event pool and initializes it with the given values. Use this function instead of creating new events. Events obtained using this method need to be released back to the pool. You can use Dispose() to release them. |
| bubbles | Returns whether this event type bubbles up in the event propagation path. |
| currentTarget | The current target of the event. This is the VisualElement, in the propagation path, for which event handlers are currently being executed. |
| dispatch | Indicates whether 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. |
| eventTypeId | Retrieves the type ID for this event instance. |
| imguiEvent | The IMGUIEvent at the source of this event. The source can be null since not all events are generated by IMGUI. |
| isDefaultPrevented | Returns true if the default actions should not be executed for this event. |
| isImmediatePropagationStopped | Indicates whether StopImmediatePropagation() was called for this event. |
| isPropagationStopped | Whether StopPropagation() was called for this event. |
| originalMousePosition | The original mouse position of the IMGUI event, before it is transformed to the current target local coordinates. |
| pooled | Whether the event is allocated from a pool of events. |
| propagationPhase | The current propagation phase for this event. |
| target | The 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. |
| timestamp | The time when the event was created, in milliseconds. |
| tricklesDown | Returns whether this event is sent down the event propagation path during the TrickleDown phase. |
| eventTypeId | Retrieves the type ID for this event instance. |
| Dispose | Implementation of IDisposable. |
| PreventDefault | Indicates whether the default actions are prevented from being executed for this event. |
| StopImmediatePropagation | Immediately stops the propagation of the event. The event isn't sent to other elements along the propagation path. This method prevents other event handlers from executing on the current target. |
| StopPropagation | Stops propagating this event. The event is not sent to other elements along the propagation path. This method does not prevent other event handlers from executing on the current target. |
| Dispose | Implementation of IDispose. |
| PostDispatch | |
| PreDispatch |
| RegisterEventType | Registers an event class to the event type system. |
| GetPooled | Gets an event from the event pool. Use this function instead of creating new events. Events obtained using this method need to be released back to the pool. You can use Dispose() to release them. |
| TypeId | Retrieves the type ID for this event instance. |
