Getting and setting hints

4 declarations

datadata Hint v where

The Hint type exports a well-typed interface to SDL's concept of hints. This type has instances for both HasGetter and HasSetter, allowing you to get and set hints. Note that the HasSetter interface is fairly relaxed - if a hint cannot be set, the failure will be silently discarded. For more feedback and control when setting hints, see setHintWithPriority.

Instances2HasGetter, HasSetter

HasSetter (Hint v) vDefined in sdl2-2.5.5.0 · SDL.Hint

valuesetHintWithPriority :: MonadIO m => HintPriority -> Hint v -> v -> m Bool

Set the value of a hint, applying priority rules for when there is a conflict. Ordinarily, a hint will not be set if there is an existing override hint or environment variable that takes precedence.

datadata HintPriority

How to deal with setting hints when an existing override or environment variable is present.

Constructors

DefaultPriority
Low priority, used for default values
NormalPriority
Medium priority
OverridePriority
High priority

HintAccelerometerAsJoystick
