Detailed Description

Long tap gesture recognizer.

SoLongTapGestureRecognizer analyses touch events and recognizes a one finger long-tap (touch-and-hold) gesture. It returns an SoLongTapGestureEvent with the long tap duration if this gesture is recognized. The finger has to stay in a limitation area from the down event to the up event and must stay down for a minimum period of time. This recognizer only generates an END event.

Member Function Documentation

SbTime SoLongTapGestureRecognizer::getMinimumLongTapDuration ( void   )  const

Gets the minimum duration of a long tap.

(Default is 1.5 seconds)

int SoLongTapGestureRecognizer::getSpatialRestriction ( void   )  const

Gets the radius of the limitation circle in which the finger has to stay throughout the gesture.

(Default is 60 pixels).

SoEvent* SoLongTapGestureRecognizer::recognize ( SoEvent touchEvent  )  [virtual]

Analyses touch events and returns an SoLongTapGestureEvent if the gesture is recognized, else returns null.

Event includes the duration of the long tap. Returns a pointer to an internal data object. Do not modify or delete this object.

Implements SoGestureRecognizer.

void SoLongTapGestureRecognizer::setMinimumLongTapDuration ( SbTime  t  ) 

Sets the minimum duration of a long tap.

(Default is 1.5 seconds)

void SoLongTapGestureRecognizer::setSpatialRestriction ( int  c  ) 

Sets the radius of the limitation circle in which the finger has to stay throughout the gesture.

(Default is 60 pixels)
