Detailed Description

Pan input manipulator recognizes a pan gesture from the incoming touch events.

It generates messages for different phases of the pan gesture. You can use these messages to implement the logic to move nodes, to pan or to flick scrollable content. For example, you can use the pan input manipulator to scroll a map.

Examples

To receive the pan move events, add message handler for the MovedMessage.

First create a handler method:

    void onPanMoved(PanManipulator::MovedMessageArguments& /*messageArguments*/)
    {
        // Insert your code to handle the pan moved event here
    }

Then add a message handler for your node:

        PanManipulatorSharedPtr panManipulator = PanManipulator::create(domain);
        node->addInputManipulator(panManipulator);
        movedMessageSubscription = node->addMessageHandler(PanManipulator::MovedMessage, bind(&InputManipulatorSnippet::onPanMoved, this, placeholders::_1));
