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:

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

void kanzi::PanManipulator::setRecognitionThreshold ( Vector2  threshold)
inline

Sets the threshold the finger must move before Kanzi recognizes it as a pan gesture.

To disable recognition along an axis, for the components of the threshold use Node2D::unboundedLayoutValue().

Parameters
thresholdThreshold in pixels required before Kanzi recognizes it as a pan gesture.
Vector2 kanzi::PanManipulator::getRecognitionThreshold ( ) const
inline

Returns the gesture recognition threshold values.

size_t kanzi::PanManipulator::getMinimumNumberOfTouches ( ) const

Returns the minimum number of touches on the node area for this gesture to be recognized.

The default is 1.

See also
getMaximumNumberOfTouches()
size_t kanzi::PanManipulator::getMaximumNumberOfTouches ( ) const

Returns the maximum number of touches on the node area for this gesture to be recognized.

The default is unlimited.
