Detailed Description

Manual binding source.

ManualBindingSource works like ObjectPropertyBindingSource, reading values from Node or RenderPass objects, but does not connect or install any listeners. Property changes cannot cause the binding to be executed.

Kanzi Engine uses ManualBindingSource internally with actions and triggers, utilizing ManualBinding.

Creating a manual binding source

To create a manual binding source:

        // Create a manual binding source.
        BindingSourcePtr manualSource = ManualBindingSource::create("../siblingNode", Node2D::OpacityProperty, PropertyFieldWhole);

Because property changes do not cause the binding to be executed, ManualBindingSourceRuntime would only read the value once when used with regular bindings - when the binding runtime is first attached. When used with ManualBinding, it would only read values when the binding runtime is explicitly updated.

Since

Kanzi 3.7.0
