Member Function Documentation

◆ OnDownEvent()

bool Gestures::RecognizerClickOrTap::OnDownEvent ( const AZ::Vector2 &  screenPositionPixels,
uint32_t  pointerIndex 
)
inlineoverridevirtual

Override to be notified each frame a mouse button or finger on a touch screen remains pressed, unless the input event was consumed by a higher priority gesture recognizer.

Parameters
[in]screenPositionPixelsThe screen position (in pixels) of the input event.
[in]pointerIndexThe pointer index of the input event.
Returns
True to consume the underlying input event (preventing it from being sent on to other lower-priority gesture recognizers or input listeners), or false otherwise.

Implements Gestures::IRecognizer.

◆ OnPressedEvent()

bool Gestures::RecognizerClickOrTap::OnPressedEvent ( const AZ::Vector2 &  screenPositionPixels,
uint32_t  pointerIndex 
)
inlineoverridevirtual

Override to be notified when a mouse button or finger on a touch screen is initially pressed, unless the input event was consumed by a higher priority gesture recognizer.

Parameters
[in]screenPositionPixelsThe screen position (in pixels) of the input event.
[in]pointerIndexThe pointer index of the input event.
Returns
True to consume the underlying input event (preventing it from being sent on to other lower-priority gesture recognizers or input listeners), or false otherwise.

Implements Gestures::IRecognizer.

◆ OnReleasedEvent()

bool Gestures::RecognizerClickOrTap::OnReleasedEvent ( const AZ::Vector2 &  screenPositionPixels,
uint32_t  pointerIndex 
)
inlineoverridevirtual

Override to be notified when a pressed mouse button or finger on a touch screen becomes released, unless the input event was consumed by a higher priority gesture recognizer.

Parameters
[in]screenPositionPixelsThe screen position (in pixels) of the input event.
[in]pointerIndexThe pointer index of the input event.
Returns
True to consume the underlying input event (preventing it from being sent on to other lower-priority gesture recognizers or input listeners), or false otherwise.

Implements Gestures::IRecognizer.
