Description

Event sent when the mouse pointer enters an element or one of its descendent elements. The event is cancellable, it does not trickle down, and it does not bubble up.

Constructors

MouseEnterEvent Constructor. Avoid creating new event instances. Instead, use GetPooled() to get an instance from a pool of reusable event instances.

Protected Methods

Init Resets the event members to their initial values.

Inherited Members

Properties

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.
actionKey Returns true if the platform-specific action key is pressed. This key is Cmd on macOS, and Ctrl on all other platforms.
altKey Returns true if the Alt key is pressed.
button Integer that indicates which mouse button is pressed: 0 is the left button, 1 is the right button, 2 is the middle button.
clickCount The number of times the button is pressed.
commandKey Returns true if the Windows/Cmd key is pressed.
ctrlKey Returns true if the Ctrl key is pressed.
currentTarget The current target of the event. The current target is the element in the propagation path for which event handlers are currently being executed.
localMousePosition The mouse position in the current target coordinate system.
modifiers Flags that hold pressed modifier keys (Alt, Ctrl, Shift, Windows/Cmd).
mouseDelta The difference of the mouse position between the previous mouse event and the current mouse event.
mousePosition The mouse position in the screen coordinate system.
pressedButtons A bitmask that describes the currently pressed buttons.
shiftKey Returns true if the Shift key is pressed.

Public Methods

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.

Protected Methods

PostDispatch Allows subclasses to perform custom logic after the event has been dispatched.
PreDispatch Allows subclasses to perform custom logic before the event is dispatched.

Static Methods

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.
GetPooled Gets an 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.
