Detailed Description

Base class for Kanzi nodes.

Kanzi messages

Use the interface provided by Node to dispatch messages and enable the nodes in the node tree to react to messages.

When you dispatch a message it travels in two phases: first tunneling, then bubbling. During the tunneling phase the message travels from the root node to the node where the message originated. From there the message bubbles back to the root node.

When you want a node to react to a message when that message passes, add message handlers or filters to those nodes. A message filter intercepts messages from any node while a message handler listens only to messages from a specific source node. To register message handlers and filters that react to:

To remove all types of handlers and filters use Node::removeMessageHandler().

To dispatch a single message, use Node::dispatchMessage().

Examples

To define a simple example node, one message type, two callbacks which are suitable for message handlers and a counting mechanism to verify the callback invocations:

// Counts how many times the callbacks are invoked to verify that the calls occur.
static int callCount = 0;
// Define an example node, which presents a message type and a callback method.
class ExampleNode : public EmptyNode2D
{
public:
// An example message type.
static MessageType<MessageArguments> exampleMessageType;
// Create the node.
static ExampleNodeSharedPtr create(Domain* domain, string_view name)
{
ExampleNodeSharedPtr node = make_polymorphic_shared_ptr<EmptyNode2D>(new ExampleNode(domain, name));
node->initialize();
return node;
}
// An example callback method.
void exampleNodeCallback(MessageArguments& message)
{
// To let the message continue moving in the node tree, set the message to not handled.
message.setHandled(false);
++callCount;
}
private:
// Construct the node.
explicit ExampleNode(Domain* domain, string_view name) :
EmptyNode2D(domain, name)
{
}
};
// An example callback function.
void exampleCallback(MessageArguments& message)
{
message.setHandled(false);
++callCount;
}
// The message type definition.
MessageType<MessageArguments> ExampleNode::exampleMessageType(kzMakeFixedString("ExampleNode.exampleMessageType"), nullptr);

To add a handler that consumes the messages sent by the node itself with Node::addMessageHandler():

// Initialize a node.
ExampleNodeSharedPtr node = ExampleNode::create(domain, "node");
// Add a message handler that intercepts messages dispatched from the node itself.
Node::MessageSubscriptionToken token = node->addMessageHandler(ExampleNode::exampleMessageType, &exampleCallback);

To remove the handler with Node::removeMessageHandler():

// Remove the handler that intercepts messages dispatched from the node itself.
node->removeMessageHandler(token);

To add a bubbling handler with Node::addMessageHandler():

// Initialize a child node.
EmptyNode2DSharedPtr child = EmptyNode2D::create(domain, "child");
// Set the node you created earlier to be the parent of the child node.
node->addChild(child);
// Add a bubbling message handler that accepts messages from the child node.
Node::MessageSubscriptionToken bubblingToken = node->addMessageHandler(ExampleNode::exampleMessageType, function<void(MessageArguments&)>(&exampleCallback), child.get());

To remove a bubbling handler with Node::removeMessageHandler():

// Remove the bubbling handler.
node->removeMessageHandler(bubblingToken);

To add a tunneling filter with Node::addTunnelingFilter():

// Add a message filter that intercepts tunneling messages.
Node::MessageSubscriptionToken tunnelingToken = node->addTunnelingFilter(ExampleNode::exampleMessageType, node.get(), &ExampleNode::exampleNodeCallback);

To remove a tunneling filter with Node::removeMessageHandler():

// Remove the tunneling filter.
node->removeMessageHandler(tunnelingToken);

To dispatch a message use Node::dispatchMessage():

// Initialize the message that you want to dispatch.
MessageArguments message;
// Dispatch the created message from the child node. If the message dispatcher has any handlers
// or filters added for ExampleNode::exampleMessageType, Kanzi invokes their callbacks immediately.
child->dispatchMessage(ExampleNode::exampleMessageType, message);

Property types

Examples

To set node properties:

// Create node and set its properties
Node3DSharedPtr objectNode;
objectNode = EmptyNode3D::create(domain, "TestNode");
objectNode->setProperty(Node::NameProperty, "NewTestNodeName");
objectNode->setProperty(Node::WidthProperty, 25);
objectNode->setProperty(Node::HorizontalMarginProperty, Vector2(5, 7));
objectNode->setProperty(Node::VisibleProperty, false);
objectNode->setProperty(Node::FontFamilyProperty, localFontFamily);
string name = objectNode->getProperty(Node::NameProperty);
float width = objectNode->getProperty(Node::WidthProperty);
Vector2 hMargin = objectNode->getProperty(Node::HorizontalMarginProperty);
bool visible = objectNode->getProperty(Node::VisibleProperty);
ResourceSharedPtr resource = objectNode->getProperty(Node::FontFamilyProperty);

template<typename DataType >
PropertyType<DataType>::Traits::ReturnType kanzi::Node::getProperty ( const PropertyType< DataType > &  propertyType) const
inline

Returns the current value of a property.

The value returned by this function is the result of the property system evaluating the inputs that can affect the values of properties. The final value is calculated by determining the base value of the property and applying existing modifiers to it.

Base value is affected by the following inputs where the highest entry in the list determines the base value:

  1. Local value set with setProperty or loaded from kzb
  2. Value set by a style affecting the property.
  3. Value defined by class metadata.

When the base value is determined the system applies modifiers to the value that can change the value or replace it completely. The following is the list of possible modifiers, where the order of evaluation is determined by the order the modifiers were added or applied.

  1. Values defined is states of state manager.
  2. Animations.

If the property metadata specifies that the property is inheritable and no inputs for the property value can be determined at the current node the system iterates the node tree to the root until inputs are found or the root is reached.

If no inputs to the property value can be established the system returns the value registered in the property type metadata.

Parameters
propertyTypeThe property type identifying the property to retrieve.
Returns
Returns the evaluated property value.

Parameters
propertyTypeThe property type identifying the property to retrieve.
Returns
Returns true if there are inputs into the property value, false otherwise.

PropertyType<bool> kanzi::Node::EnabledProperty
static

Sets whether the node is enabled.

When you set the EnabledProperty to false for a node, also its descendant nodes in the same overlay scope are effectively disabled. Effectively disabling a node removes that node from the focus chain and cancels the active input manipulators. Use the EffectivelyEnabledProperty to observe whether a node is effectively enabled. The default value is true.

See also
Node::EffectivelyEnabledProperty, setEnabled(), isEnabled()
PropertyType<bool> kanzi::Node::EffectivelyEnabledProperty
static

Indicates whether the node and its ancestor nodes are enabled.

To enable or disable a node, use the EnabledProperty. Use the EffectivelyEnabledProperty in state managers and bindings to observe whether a node is effectively enabled. When a node is effectively disabled:

  • When the node is focused, the node receives key input until the focus moves to another node.
  • When the node is not focused, the node is not part of the focus chain and does not receive key input.

The default value is true.
