Detailed Description

Examples

To create a Slider 2D node with a custom appearance:

        // Create a Slider 2D node named Custom 2D slider.
        Slider2DSharedPtr slider = Slider2D::create(domain, "Custom 2D slider");
        // Set the size of the Slider 2D node to be 400 pixels wide and 200 pixels high.
        slider->setSize(400.0f, 200.0f);

        // Use the Trajectory Layout 2D node to define the rail along which the knob of the slider moves.
        // Create a Trajectory Layout 2D node named Slider rail.
        TrajectoryLayout2DSharedPtr trajectoryLayout = TrajectoryLayout2D::create(domain, "Slider rail");

        // Use the Image node to define the look of the knob that moves on the slider rail.
        // Create an Image node named Slider knob.
        Image2DSharedPtr knob = Image2D::create(domain, "Slider knob");
        // Set the Image node to be the child of the trajectoryLayout Trajectory Layout 2D node.
        trajectoryLayout->addChild(knob);

        // Create an alias pointing to the Trajectory Layout 2D node that defines the slider rail.
        ResourceID alias("$layout");
        string path("obj:///" + trajectoryLayout->getName());
        // Add the alias to the resource dictionary of the Slider 2D node.
        slider->addResource(alias, path);

        // Add the layout as a child node of the Slider 2D node.
        // You can place the Trajectory Layout 2D node that defines the rail anywhere
        // in the scene graph and it does not have to be the direct child of the Slider 2D node.
        slider->addChild(trajectoryLayout);

        // Create the trajectory of the Trajectory Layout 2D node that is used as the rail of the Slider 2D node.
        // Create a line trajectory on the x axis, that is 350 pixels long, and name it Line trajectory.
        TrajectorySharedPtr trajectory = Trajectory::createLine(Vector3(), Vector3(1.0f, 0.0f, 0.0f), 350.0f, domain, "Line trajectory");
        // Set the Trajectory Layout 2D node to use the line trajectory.
        trajectoryLayout->setTrajectory(trajectory);

        // Set the Trajectory Layout 2D node so that it sets its size
        // based on the size of its parent node (in this case the Slider 2D node).
        trajectoryLayout->setHorizontalAlignment(Node::HorizontalAlignmentStretch);
        trajectoryLayout->setVerticalAlignment(Node::VerticalAlignmentStretch);

        // The knob movement on the rail is based on modifying the TrajectoryLayout2D::StaticTrajectoryOffsetProperty
        // which is set based on the Slider2D::ValueProperty.
        // "../.." is the path from the knob (Image node) to the Slider 2D node.
        BindingSharedPtr binding = Binding::create(domain, "../..", Slider2D::ValueProperty,
                                                                   PropertyFieldWhole,
                                                                   TrajectoryLayout2D::OverrideOffsetProperty,
                                                                   PropertyFieldWhole);

        // Add the Slider 2D node to the Viewport 2D node.
        viewportNode->addChild(slider);

        // Get the knob instance from the instance of the prefab template.
        Node2DSharedPtr knobInstance = slider->getPresenter()->getLayout()->getChild(0);
        // Add to the knob the binding that enables the knob to move on the rail.
        knobInstance->addBinding(binding);
