Relative Mouse Mode

data LocationMode

Constructors

AbsoluteLocation

RelativeLocation

Instances

Eq LocationMode

Methods

(==) :: LocationMode -> LocationMode -> Bool

(/=) :: LocationMode -> LocationMode -> Bool

setMouseLocationMode :: (Functor m, MonadIO m) => LocationMode -> m LocationMode

Sets the current relative mouse mode.

When relative mouse mode is enabled, cursor is hidden and mouse position will not change. However, you will be delivered relative mouse position change events.

getMouseLocationMode :: MonadIO m => m LocationMode

Check which mouse location mode is currently active.

setRelativeMouseMode :: (Functor m, MonadIO m) => Bool -> m ()

Deprecated: Use setMouseLocationMode instead

getRelativeMouseMode :: MonadIO m => m Bool

Deprecated: Use getMouseLocationMode instead
