Detailed Description

Multi-click input manipulator recognizes multi-click and multi-tap gestures from incoming touch events.

It generates the messages required to implement the logic for nodes that change the state when users multi-click or multi-tap the node. For example, use the multi-click input manipulator to zoom in and out a map.

See also

ClickManipulator, DragAndDropManipulator, LongPressManipulator, PanManipulator, PinchManipulator

Examples

To receive the multi-click event, add a message handler for the MultiClickMessage message.

First create a handler method:

    void onNodeDoubleClicked(MultiClickManipulator::MultiClickMessageArguments& /*messageArguments*/)
    {
        // Insert your code to handle the click event here
    }

Then add a message handler for your node:

        ClickManipulatorSharedPtr doubleClickManipulator = ClickManipulator::create(domain);
        node->addInputManipulator(doubleClickManipulator);

        doubleClickMessageSubscription = node->addMessageHandler(MultiClickManipulator::MultiClickMessage, bind(&InputManipulatorSnippet::onNodeDoubleClicked, this, placeholders::_1));

inlinestatic

void kanzi::MultiClickManipulator::setTimeout

(

chrono::milliseconds

timeout

)

Sets the multi-click timeout in milliseconds.

If the time between each click does not exceed this value, the MultiClickManipulator recognizes these clicks as a multi-click gesture. The default multi-click timeout is 250 ms.

void kanzi::MultiClickManipulator::setClickCount

(

int

clickCount

)

Sets the value of the ClickCountProperty property.

Parameters

clickCount

The value set in the ClickCountProperty property.

int kanzi::MultiClickManipulator::getClickCount

(

)

const

Gets the value of the ClickCountProperty property.

Returns

The value of the ClickCountProperty property.

bool kanzi::MultiClickManipulator::getSendIntermediateClickMessages

(

)

const

Returns whether the multi-click manipulator sends intermediate IntermediateClickMessage messages before it sends the MultiClickMessage.

Returns

If the multi-click manipulator sends intermediate IntermediateClickMessage messages, returns true, otherwise false.

Since

Kanzi 3.8.0

void kanzi::MultiClickManipulator::setSendIntermediateClickMessages

(

bool

triggerOn

)

Sets whether to send intermediate IntermediateClickMessage messages before the MultiClickMessage is sent.

Parameters

triggerOn

The sending state for the IntermediateClickMessage messages.

Since

Kanzi 3.8.0

virtual bool kanzi::MultiClickManipulator::clickDetected ( KzuInputTouchPoint const &  touchPoint, unsigned int  clickCount  )

protectedvirtual

Overridable method that is called whenever a click is detected.

By default this method checks that the clickCount matches the required click count (getClickCount()) and calls sendMultiClickMessage() when this happens. If the clickCount does not match and the manipulator is configured to send intermediate click messages, a IntermediateClickMessage message is dispatched.

Parameters

touchPoint	The touch point where the click occurred.
clickCount	How many clicks have been detected so far.

Returns

If a multi-click detection is ongoing, true. If a multi-click detection was finished and a MultiClickMessage message was dispatched, false.

setSendIntermediateClickMessages(), getSendIntermediateClickMessages()

void kanzi::MultiClickManipulator::sendMultiClickMessage ( const KzuInputTouchPoint &  touchPoint, unsigned int  clickCount  )

protected

Constructs and sends a MultiClickMessage message.

If there is a fail input manipulator set with the InputManipulator::requireToFail method, the message is delayed until the fail input manipulator has failed. If the fail never happens the message is not sent.

Parameters

touchPoint	The touch point where the click occurred.
clickCount	How many clicks have been detected so far.

Member Data Documentation

const chrono::milliseconds kanzi::MultiClickManipulator::defaultMultiClickTimeout

static

The default multi-click timeout constant.

MessageType<MultiClickMessageArguments> kanzi::MultiClickManipulator::MultiClickMessage

static

Notifies about the recognition of a multi-click gesture.

MultiClickManipulator sends this message when it detects the last click of the number of clicks set by the ClickCountProperty. Multi-click fails if some other gesture succeeds before it.

MessageType<MultiClickMessageArguments> kanzi::MultiClickManipulator::IntermediateClickMessage

static

Notifies about the recognition of intermediate click gestures.

MultiClickManipulator sends this message after each successfully completed click gesture.

Since

Kanzi 3.8.0

MessageType<CanceledMessageArguments> kanzi::MultiClickManipulator::CanceledMessage

static

Notifies about the cancellation of a multi-click gesture.

The CanceledMessage message is generated when MultiClickManipulator is canceled.

PropertyType<int> kanzi::MultiClickManipulator::ClickCountProperty

static

Sets the number of clicks required to send the MultiClickMessage message. The default value is 2.
