GI.Gtk.Objects.StyleProperties

GtkStyleProperties provides the storage for style information that is used by StyleContext and other StyleProvider implementations.

Before style properties can be stored in GtkStyleProperties, they must be registered with gtk_style_properties_register_property().

Unless you are writing a StyleProvider implementation, you are unlikely to use this API directly, as gtk_style_context_get() and its variants are the preferred way to access styling information from widget implementations and theming engine implementations should use the APIs provided by ThemingEngine instead.

StyleProperties has been deprecated in GTK 3.16. The CSS machinery does not use it anymore and all users of this object have been deprecated.

clear

stylePropertiesClear

Arguments

:: (HasCallStack, MonadIO m, IsStyleProperties a)

=> a

props: a StyleProperties

-> m ()

Deprecated: (Since version 3.16)tStyleProperties are deprecated.

Clears all style information from props.

getProperty

stylePropertiesGetProperty

Arguments

:: (HasCallStack, MonadIO m, IsStyleProperties a)

=> a

props: a StyleProperties

-> Text

property: style property name

-> [StateFlags]

state: state to retrieve the property value for

-> m (Bool, GValue)

Returns: True if the property exists in props, False otherwise

Deprecated: (Since version 3.16)tStyleProperties are deprecated.

Gets a style property from props for the given state. When done with value, valueUnset needs to be called to free any allocated memory.

Since: 3.0

lookupColor

stylePropertiesLookupColor

Arguments

:: (HasCallStack, MonadIO m, IsStyleProperties a)

=> a

props: a StyleProperties

-> Text

name: color name to lookup

-> m SymbolicColor

Returns: The mapped color

Deprecated: (Since version 3.8)tSymbolicColor is deprecated.

Returns the symbolic color that is mapped to name.

Since: 3.0

mapColor

stylePropertiesMapColor

Arguments

:: (HasCallStack, MonadIO m, IsStyleProperties a)

=> a

props: a StyleProperties

-> Text

name: color name

-> SymbolicColor

color: SymbolicColor to map name to

-> m ()

Deprecated: (Since version 3.8)tSymbolicColor is deprecated.

Maps color so it can be referenced by name. See stylePropertiesLookupColor

Since: 3.0

merge

stylePropertiesMerge

propsToMerge: a second StyleProperties

-> Bool

replace: whether to replace values or not

-> m ()

Deprecated: (Since version 3.16)tStyleProperties are deprecated.

Merges into props all the style information contained in propsToMerge. If replace is True, the values will be overwritten, if it is False, the older values will prevail.

Since: 3.0
