Detailed Description

KeyManipulator class is a key input manipulator that detects key gestures.

Kanzi recognizes a key gesture when it receives an event with a key code and an optional key modifier. When Kanzi recognizes a key gesture, an input manipulator:

  1. Grabs the gesture.
  2. Enters the StateBegin state.
  3. Dispatches to an attached node the KeyPressedMessage with the logical key value and the pressed key modifiers.

The input manipulator that grabs a key gesture continues to stay in the StateBegin state until it receives a key up event with a logical key value, or a key modifier that forms a key gesture.

The key input manipulators are exclusive input manipulators. To handle different key gestures, you can add multiple key manipulators.

To handle the press and release of the A key:

auto keyManipulator = KeyManipulator::create(getDomain());
anyNode->addInputManipulator(keyManipulator);
keyManipulator->setKey(LogicalKey::A);
auto onKeyPressed = [](auto&)
{
// Handle the key press.
};
anyNode->addMessageHandler(KeyManipulator::KeyPressedMessage, onKeyPressed);
auto onKeyReleased = [](auto&)
{
// Handle the key release.
};
anyNode->addMessageHandler(KeyManipulator::KeyReleasedMessage, onKeyReleased);

To handle the Left Control modifier key as a key gesture:

keyManipulator->setKey(LogicalKey::LeftControl);

To handle a key gesture composed of the Shift + A keys:

keyManipulator->setKey(LogicalKey::A, KeyModifier::Shift);

To handle the Left Alt + Left Control modifier keys, set the Left Alt as modifier key:

The key press order matters. Pressing Left Control first and then Left Alt does not result in the same key gesture as pressing first Left Alt, then Left Control. To handle the Left Control + Left Alt key gesture:
