Monomer.Widgets.Util.Types

Description

Common types for widget related functions.

Synopsis

type IsHovered s e = WidgetEnv s e -> WidgetNode s e -> Bool
type IsFocused s e = WidgetEnv s e -> WidgetNode s e -> Bool
type IsActive s e = WidgetEnv s e -> WidgetNode s e -> Bool
type GetBaseStyle s e = WidgetEnv s e -> WidgetNode s e -> Maybe Style
data CurrentStyleCfg s e = CurrentStyleCfg {
- _ascIsHovered :: IsHovered s e
- _ascIsFocused :: IsFocused s e
- _ascIsActive :: IsActive s e
}

Documentation

type IsHovered s e = WidgetEnv s e -> WidgetNode s e -> Bool Source #

Indicates whether the mouse pointer is over a valid region the given node.

type IsFocused s e = WidgetEnv s e -> WidgetNode s e -> Bool Source #

Indicates whether the given node has keyboard focus.

type IsActive s e = WidgetEnv s e -> WidgetNode s e -> Bool Source #

Indicates whether the given node is clicked on a valid region.

type GetBaseStyle s e = WidgetEnv s e -> WidgetNode s e -> Maybe Style Source #

Returns the base style for a given node, if any. This is widget dependent.

Usually this style comes from the active theme.

data CurrentStyleCfg s e Source #

Configuration for style related functions. It allows to override how each of the states (hovered, focused and active) is defined for a given widget type.

A usage example can be found in Monomer.Widgets.Radio.
