Description

Dial widget, used for interacting with numeric values. It allows changing the value using the keyboard arrows, dragging the mouse or using the wheel.

dial numericLens 0 100

Similar in objective to Monomer.Widgets.Singles.Slider, but uses less visual space in its parent container.

Synopsis

type DialValue a = (Eq a, Show a, Real a, FromFractional a, Typeable a)
data DialCfg s e a
dial :: (DialValue a, WidgetEvent e) => ALens' s a -> a -> a -> WidgetNode s e
dial_ :: (DialValue a, WidgetEvent e) => ALens' s a -> a -> a -> [DialCfg s e a] -> WidgetNode s e
dialV :: (DialValue a, WidgetEvent e) => a -> (a -> e) -> a -> a -> WidgetNode s e
dialV_ :: (DialValue a, WidgetEvent e) => a -> (a -> e) -> a -> a -> [DialCfg s e a] -> WidgetNode s e
dialD_ :: (DialValue a, WidgetEvent e) => WidgetData s a -> a -> a -> [DialCfg s e a] -> WidgetNode s e

Configuration

type DialValue a = (Eq a, Show a, Real a, FromFractional a, Typeable a) Source #

Constraints for numeric types accepted by dial.

data DialCfg s e a Source #

Configuration options for dial:

width: sets the max width/height of the dial.
wheelRate: The rate at which wheel movement affects the number.
dragRate: The rate at which drag movement affects the number.
onFocus: event to raise when focus is received.
onFocusReq: WidgetRequest to generate when focus is received.
onBlur: event to raise when focus is lost.
onBlurReq: WidgetRequest to generate when focus is lost.
onChange: event to raise when the value changes.
onChangeReq: WidgetRequest to generate when the value changes.
