Description

GtkStyleProvider is an interface used to provide style information to a StyleContext. See styleContextAddProvider and styleContextAddProviderForScreen.

Synopsis

newtype StyleProvider = StyleProvider (ManagedPtr StyleProvider)
noStyleProvider :: Maybe StyleProvider
class (ManagedPtrNewtype o, IsDescendantOf StyleProvider o) => IsStyleProvider o
styleProviderGetIconFactory :: (HasCallStack, MonadIO m, IsStyleProvider a) => a -> WidgetPath -> m (Maybe IconFactory)
styleProviderGetStyle :: (HasCallStack, MonadIO m, IsStyleProvider a) => a -> WidgetPath -> m (Maybe StyleProperties)
styleProviderGetStyleProperty :: (HasCallStack, MonadIO m, IsStyleProvider a) => a -> WidgetPath -> [StateFlags] -> GParamSpec -> m (Bool, GValue)

Methods

getIconFactory

styleProviderGetIconFactory Source #

Arguments

:: (HasCallStack, MonadIO m, IsStyleProvider a)
=> a	`provider`: a `StyleProvider`
-> WidgetPath	`path`: `WidgetPath` to query
-> m (Maybe IconFactory)	Returns: The icon factory to use for `path`, or `Nothing`

Deprecated: (Since version 3.8)Will always return Nothing for all GTK-provided style providers.

Returns the IconFactory defined to be in use for path, or Nothing if none is defined.

Since: 3.0

getStyle

styleProviderGetStyle Source #

Arguments

:: (HasCallStack, MonadIO m, IsStyleProvider a)
=> a	`provider`: a `StyleProvider`
-> WidgetPath	`path`: `WidgetPath` to query
-> m (Maybe StyleProperties)	Returns: a `StyleProperties` containing the style settings affecting `path`

Deprecated: (Since version 3.8)Will always return Nothing for all GTK-provided style providers as the interface cannot correctly work the way CSS is specified.

Returns the style settings affecting a widget defined by path, or Nothing if provider doesn’t contemplate styling path.

Since: 3.0

getStyleProperty

styleProviderGetStyleProperty Source #

Arguments

:: (HasCallStack, MonadIO m, IsStyleProvider a)
=> a	`provider`: a `StyleProvider`
-> WidgetPath	`path`: `WidgetPath` to query
-> [StateFlags]	`state`: state to query the style property for
-> GParamSpec	`pspec`: The `ParamSpec` to query
-> m (Bool, GValue)	Returns: `True` if the property was found and has a value, `False` otherwise

Looks up a widget style property as defined by provider for the widget represented by path.

Since: 3.0
