A click consists of a mouse down event followed by a mouse up event on the same VisualElement. The mouse might move between the two events.

Constructors

Properties

bubblesWhether this event type bubbles up in the event propagation path.
currentTargetThe current target of the event. This is the VisualElement, in the propagation path, for which event handlers are currently being executed.
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.
eventTypeIdRetrieves the type ID for this event instance.
imguiEventThe IMGUIEvent at the source of this event. The source can be null since not all events are generated by IMGUI.
isDefaultPreventedReturn true if the default actions should not be executed for this event.
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.
propagationPhaseThe current propagation phase.
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.
eventTypeIdRetrieves the type ID for this event instance.
actionKeyReturns true if the platform-specific action key is pressed. This key is Cmd on macOS, and Ctrl on all other platforms.
altitudeAngleAngle of the stylus relative to the surface, in radians
altKeyReturns true if the Alt key is pressed.
azimuthAngleAngle of the stylus relative to the x-axis, in radians.
buttonInteger that indicates which mouse button is pressed: 0 is the left button, 1 is the right button, 2 is the middle button.
clickCountThe number of times the button is pressed.
commandKeyReturns true if the Windows/Cmd key is pressed.
ctrlKeyReturns true if the Ctrl key is pressed.
currentTargetThe current target of the event. The current target is the element in the propagation path for which event handlers are currently being executed.
deltaPositionThe difference between the pointer's position during the previous mouse event and its position during the current mouse event.
deltaTimeThe amount of time that has passed since the last recorded change in pointer values, in seconds.
isPrimaryReturns true if the pointer is a primary pointer
localPositionThe pointer position in the current target coordinate system.
modifiersFlags that hold pressed modifier keys (Alt, Ctrl, Shift, Windows/Cmd).
pointerIdIdentifies the pointer that sends the event.
pointerTypeThe type of pointer that created this event. This value is taken from the value defined in `PointerType`.
positionThe pointer position in the Screen or World coordinate system.
pressedButtonsA bitmask that describes the currently pressed buttons.
pressureThe amount of pressure currently applied by a touch. If the device does not report pressure, the value of this property is 1.0f.
radiusAn estimate of the radius of a touch. Add `radiusVariance` to get the maximum touch radius, subtract it to get the minimum touch radius.
radiusVarianceDetermines the accuracy of the touch radius. Add this value to the radius to get the maximum touch radius, subtract it to get the minimum touch radius.
shiftKeyReturns true if the Shift key is pressed.
tangentialPressureThe pressure applied to an additional pressure-sensitive control on the stylus.
twistThe rotation of the stylus around its axis, in radians.

Public Methods

DisposeImplementation of IDisposable.
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.
StopPropagationStops 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.
DisposeImplementation of IDispose.

Protected Methods

InitResets all event members to their initial values.

Static Methods

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 using this method need to be released back to the pool. You can use `Dispose()` to release them.
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 using this method need to be released back to the pool. You can use `Dispose()` to release them.
