The recognizer receives input events - through the \l{QGesture::}{filterEvent()} virtual function and decides - whether the event should change the state of the recognizer by emitting an - appropriate signal. + A QGesture instance is created when the application calls QWidget::grabGesture() + or QGraphicsObject::grabGesture() to configure a widget or graphics object (the + target object) for gesture input. One gesture object is created for each target + object. - Input events should be either fed to the recognizer one by one with a - filterEvent() function, or the gesture recognizer should be attached to an - object it filters events for by specifying it as a parent object. The - QGesture object installs itself as an event filter to the parent object - automatically, the unsetObject() function should be used to remove an event - filter from the parent object. To make a - gesture that operates on a QGraphicsItem, both the appropriate QGraphicsView - should be passed as a parent object and setGraphicsItem() functions should - be used to attach a gesture to a graphics item. + The registered gesture recognizer monitors the input events for the target + object via its \l{QGestureRecognizer::}{filterEvent()} function, updating the + properties of the gesture object as required. - This is a base class, to create a custom gesture type, you should subclass - it and implement its pure virtual functions. + The gesture object may be delivered to the target object in a QGestureEvent if + the corresponding gesture is active or has just been canceled. Each event that + is delivered contains a list of gesture objects, since support for more than + one gesture may be enabled for the target object.

Instances will be created behind the scenes by the + framework. + + \section1 Recognizing Gestures + + The process of recognizing gestures involves filtering input events sent to specific + objects, and modifying the associated QGesture objects to include relevant information + about the user's input. + + Gestures are created when the framework calls createGesture() to handle user input + for a particular instance of a QWidget or QGraphicsObject subclass. A QGesture object + is created for each widget or item that is configured to use gestures. + + Once a QGesture has been created for a target object, the gesture recognizer will + receive events for it in its filterEvent() handler function. + + When a gesture is canceled, the reset() function is called, giving the recognizer the + chance to update the appropriate properties in the corresponding QGesture object. + + \section1 Supporting New Gestures + + To add support for new gestures, you need to derive from QGestureRecognizer to create + a custom recognizer class, construct an instance of this class, and register it with + the application by calling QApplication::registerGestureRecognizer(). You can also + subclass QGesture to create a custom gesture class, or rely on dynamic properties + to express specific details of the gesture you want to handle. + + Your custom QGestureRecognizer subclass needs to reimplement the filterEvent() function + to handle and filter the incoming input events for QWidget and QGraphicsObject subclasses. + Although the logic for gesture recognition is implemented in this function, you can + store persistent information about the state of the recognition process in the QGesture + object supplied. The filterEvent() function must return a value of Qt::GestureState that + indicates the state of recognition for a given gesture and target object. This determines + whether or not a gesture event will be delivered to a target object. + + If you choose to represent a gesture by a custom QGesture subclass, you will need to + reimplement the createGesture() function to construct instances of your gesture class. + Similarly, you may need to reimplement the reset() function if your custom gesture + objects need to be specially handled when a gesture is canceled. + + \sa QGesture +*/ + +/*! + \enum QGestureRecognizer::ResultFlags + + This enum describes the result of the current event filtering step in + a gesture recognizer state machine. + + The result consists of a state value (one of Ignore, NotGesture, + MaybeGesture, GestureTriggered, GestureFinished) and an optional hint + (ConsumeEventHint). + + \value Ignore The event does not change the state of the recognizer. + + \value NotGesture The event made it clear that it is not a gesture. If the + gesture recognizer was in GestureTriggered state before, then the gesture + is canceled and the appropriate QGesture object will be delivered to the + target as a part of a QGestureEvent. + + \value MaybeGesture The event changed the internal state of the recognizer, + but it isn't clear yet if it is a gesture or not.
