Monomer.Widgets.Singles.OptionButton

Option button widget, used for choosing one value from a fixed set. Each instance of optionButton is associated with a single value.

optionButton "First option" Option1 optionLens

Its behavior is equivalent to Monomer.Widgets.Singles.Radio and Monomer.Widgets.Singles.LabeledRadio, with a different visual representation.

This widget, and the associated Monomer.Widgets.Singles.ToggleButton, uses two separate styles for the On and Off states which can be modified individually for the theme. If you use any of the the standard style functions (styleBasic, styleHover, etc) in an optionButton/toggleButton these changes will apply to both On and Off states, except for the color related styles. The reason is that, in general, the font and padding will be the same for both states, but the colors will differ. The optionButtonOffStyle option, which receives a Style instance, can be used to change the colors of the Off state. The values set with this option are higher priority than any inherited style from the theme or node text style.

Style instances can be created this way:

newStyle :: Style = def
  `styleBasic` [textSize 20]
  `styleHover` [textColor white]

Configuration

type OptionButtonValue a = (Eq a, Typeable a)
