Explorer Types

Doodle Explore provides several Explore* traits with implementations for the Java2D and Laminar backends. Example usage of all of these traits can be found in the *Explorer functions in doodle.explore.laminar.

ExploreInt

ExploreInt describes a DSL for adding an integer input to your GUI. It's the simplest explorer type and a good start point for understanding the library. Like most explorer types, it has an IntComponentOps module which provides some helpful extension methods.

ExploreColor

ExploreColor is another simple type of input. Implementing it for a specific backend will require converting to and from the backend's color type to doodle.core.Color.

ExploreBoolean

ExploreBoolean provides a DSL for boolean inputs. It differs from ExploreInt in that it provides methods to construct the input component as either a button or as a checkbox. In button mode, a component will emit true for only the frame that it is clicked, which is useful for simulations that make use of exploreWithState, but not for still images.

ExploreChoice

ExploreChoice represents a component allowing a user to choose options from a list. Because it is generic over the type of option, it uses a wrapper Choice type to prevent using methods from other Explore* DSLs. For choice types with a useful toString implementation, the default choice(label, choices) function will work. However, it may be better to use labeledChoice instead in order to explicitly label your choices.
