Detailed Description

Click input manipulator recognizes the click and tap gestures from the incoming touch events.

The click manipulator generates the messages required to implement the logic for UI elements that users can click or tap. For example, use the input manipulator to create a button.

DragAndDropManipulator, LongPressManipulator, MultiClickManipulator, PanManipulator, PinchManipulator

Examples

To receive the click event, add a message handler for the ClickMessage message.

First create a handler method:

void onNodeClicked(ClickManipulator::ClickMessageArguments& /*messageArguments*/)
{
// Insert your code to handle the click event here
}

Then add a message handler for your node:

node->addInputManipulator(clickManipulator);
clickMessageSubscription = node->addMessageHandler(ClickManipulator::ClickMessage, bind(&InputManipulatorSnippet::onNodeClicked, this, placeholders::_1));

To configure the click manipulator to work together with the multi-click manipulator, you need to configure the click manipulator to wait for the failure of the multi-click:

node->addInputManipulator(clickManipulator);
MultiClickManipulatorSharedPtr doubleClickManipulator =
node->addInputManipulator(doubleClickManipulator);
doubleClickManipulator->setClickCount(2);
MultiClickManipulatorSharedPtr tripleClickManipulator =
tripleClickManipulator->setClickCount(3);
node->addInputManipulator(tripleClickManipulator);
// Configure the click manipulator to wait for the failure of the double-click manipulator.
clickManipulator->requireToFail(doubleClickManipulator);
// Configure the double-click manipulator to wait for the failure of the triple-click manipulator
doubleClickManipulator->requireToFail(tripleClickManipulator);

Member Data Documentation

MessageType<ClickMessageArguments> kanzi::ClickManipulator::ClickMessage
static

Message type for notifying recognition of click gesture.

Kanzi generates a click message when the user releases a tracked touch over an attached node, or when the fail manipulator fails.

See also
InputManipulator::requireToFail
MessageType<ClickBeginMessageArguments> kanzi::ClickManipulator::ClickBeginMessage
static

Message type that you can use to notify the beginning of a click gesture.

Kanzi generates the ClickBeginMessage in these cases:

  • When the user presses the attached node. This is the default behavior.
  • If you set a gesture to start on hover with the setHoverToBegin function, the click gesture begins when the touch enters a node area while the user presses their finger.
MessageType<ClickCancelMessageArguments> kanzi::ClickManipulator::ClickCancelMessage
static

Message type for notifying cancellation of click gesture.

Click gesture is canceled when the tracked touch is released outside the node area, or when the fail manipulator succeeds (see InputManipulator::requireToFail).

MessageType<ClickEnterMessageArguments> kanzi::ClickManipulator::ClickEnterMessage
static

Message type for notifying the tracked touch entering the node area.

Click enter message is generated when touch is pressed over the node area or when the touch returns to the node area after leaving it.

MessageType<ClickLeaveMessageArguments> kanzi::ClickManipulator::ClickLeaveMessage
static

Message type for notifying the tracked touch leaving the node area.

Click leave message is generated when the pointer leaves the area or when the click gesture is completed or canceled.
