Core

The Core Controls are a set of Controls, designed to provide a minimal core set of functionality. Therefore, the Core Controls also reduce their size and provide increased performance, by limiting its feature set and reducing the number of used behaviors.

The Core Controls are designed for

Low-End Platforms
Low memory footprint and increased performance by reduced feature set
Basis for custom Controls
As the Core Controls cover basic features, it is easy possible to extend them for custom behavior (e.g. a specific custom behavior for a custom button) instead of stripping down a full featured Control

Please note, that the not all Controls have a Core Control variant, as it is not suitable for all available Controls.

CoreDial

This control is used to set values within a specified range. Rotating the knob changes the value and updates the corresponding display. The degree of rotation is adjusted according to the configured Step Size and snaps to predefined positions. The knob's state is represented by displaying an image from the BackgroundImages list corresponding to the current value. For example, in a three-step rotation setup where the minimum rotation is -45 degrees, the maximum rotation is +45 degrees, and the step size is 45 degrees, three BackgroundImages need to be assigned. Additionally, values can be adjusted using specified keyboard keys (Increment Key Code, Decrement Key Code).

In the Core version, focus and color blending functionalities are not included, and the design is specialized for basic rotational operations.
