Constructor & Destructor Documentation

◆ TouchEvent()

stmi::TouchEvent::TouchEvent ( int64_t  nTimeUsec,
const shared_ptr< Accessor > &  refAccessor,
const shared_ptr< TouchCapability > &  refTouchCapability,
TOUCH_INPUT_TYPE  eType,
double  fX,
double  fY,
int64_t  nFingerId 
)
noexcept

Constructor.

Parameters
nTimeUsecTime from epoch in microseconds.
refAccessorThe accessor used to generate the event. Can be null.
refTouchCapabilityThe capability that generated this event. Cannot be null.
eTypeThe touch event type.
fXThe X position of the touch.

nFingerIdThe id of the finger performing the touch.

Member Function Documentation

◆ getCapability()

shared_ptr<Capability> stmi::TouchEvent::getCapability ( ) const
inlineoverridevirtualnoexcept

Returns the capability that generated this event.

The Event subclass implementation keeps only a weak_ptr on the capability to avoid reference cycles.

Returns
The capability or null if the capability was deleted.

Implements stmi::Event.

◆ getClass()

static const Event::Class& stmi::TouchEvent::getClass ( )
inlinestaticnoexcept

◆ getFingerId()

int64_t stmi::TouchEvent::getFingerId ( ) const
inlinenoexcept

The finger id performing the touch.

◆ getTouchCapability()

shared_ptr<TouchCapability> stmi::TouchEvent::getTouchCapability ( ) const
inlinenoexcept

The touch capability that generated the event.

Returns
The capability or null if the capability was deleted.

◆ getType()

TOUCH_INPUT_TYPE stmi::TouchEvent::getType ( ) const
inlinenoexcept

The touch event type.

◆ setTouchCapability()

void stmi::TouchEvent::setTouchCapability ( const shared_ptr< TouchCapability > &  refTouchCapability)
inlineprotectednoexcept

Sets the capability.

Parameters
refTouchCapabilityThe capability that generated this event. Cannot be null.

◆ setTypeAndFinger()

void stmi::TouchEvent::setTypeAndFinger ( TOUCH_INPUT_TYPE  eType,
int64_t  nFingerId 
)
inlineprotectednoexcept

Sets touch and grab fields.

This method also calls XYEvent::setXYGrab().

Parameters
eTypeThe touch event type.
nFingerIdThe finger id performing the touch.
