Detailed Description

Use the Scroll View 2D node to create an input plane to enable user input from gestures.

For example, you can use the scroll message with its parameters generated by a Scroll View node to move a map plane or rotate a mesh.

When you create a Scroll View node it does not have a visual shape and does not necessarily need visible content, but can instead work as an interactive surface. When a user interacts with a Scroll View node, the action generates a message that travels to the Scroll View node where you can define the behavior for that message.

The Scroll View reports changes of its scroll position through the Scroll View: Scrolled message. You can add actions to react to these messages to, for example, set the position of an object according to the scrolling.

Note that Scroll View 2D node has location, position, and size in 2D space. It registers user input in 2D coordinates within the area defined by the size of the Scroll View 2D node. Take this into account when designing interaction with the Scroll View 2D. For example, if you rotate the Scroll View 2D node, the scroll input gets distorted.

For a 3D scroll view component, see ScrollView3D.

Examples

To create a Scroll View 2D node that animates the transformation of a 2D node in response to scroll messages:

// Declare the variable for storing the Scroll View node used in this example.
// Declare the variable for storing the Text node created in this example.
Node2DSharedPtr textNode;
// Define the handler function for the ScrollView2D.Scrolled message from the scroll view.
void onScrollViewScrolled(ScrollView2D::ScrollMessageArguments& messageArguments)
{
// Make a 2D vector out of the Scroll View node's scroll position X/Y values.
Vector2 translation = Vector2(messageArguments.getScrollPositionX(), messageArguments.getScrollPositionY());
// Set the above 2D vector as the Text node's render translation.
textNode->setRenderTransformation(SRTValue2D::createTranslation(translation));
}
// Create the Scroll View which uses the ScrollView2D.Scrolled message handler.
void exampleSetupScrollView2D()
{
// Create Scroll View node and attach to that node a Text Block 2D node.
scrollView = ScrollView2D::create(domain, "Scroll View");
scrollView->setLayoutSize(100.0f, 100.0f);
// Create a Text node and attach it to the Scroll View 2D node.
textNode = TextBlock2D::create(domain, "Hello world!");
scrollView->addChild(textNode);
// Add a message handler for the ScrollView2D.Scrolled message from the Scroll View node.
scrollView->addMessageHandler(ScrollView2D::ScrolledMessage, bind(&ScrollView2DSnippet::onScrollViewScrolled, this, placeholders::_1));
}

Constructor & Destructor Documentation

string_view  name 
)
explicitprotected

Constructor.

Parameters
domainThe UI domain the new node belongs to.
nameThe name of the node.

Member Function Documentation

static ScrollView2DSharedPtr kanzi::ScrollView2D::create ( Domain domain,
string_view  name 
)
static

Creates a scroll view with the default settings.

Parameters
domainThe UI domain the new node belongs to.
nameName of the node.
static PropertyTypeEditorInfoSharedPtr kanzi::ScrollView2D::makeEditorInfo ( )
static
optional<Vector2> kanzi::ScrollView2D::calculatePanPosition ( const optional< Vector2 > &  point) const

Calculates pan position for given point.

Parameters
pointPoint that comes from input manipulator.
optional<Vector2> kanzi::ScrollView2D::calculatePanPosition ( const InputManipulator::InputMessageArguments arguments) const

Calculates pan position for message arguments.

Parameters
argumentsMessage arguments from input manipulator.
bool kanzi::ScrollView2D::useDirectionalRecognitionThreshold ( ) const
inline

Scroll view 2D can use directional pan threshold, since the mapping between 2D input and 2D pan direction is possible.
