Implementations

impl ThemeManager

pub fn new() -> ThemeManager

pub fn add_resources(&self, resource_path: &str)

This will automatically register resources found within resource_path.

If resource_path starts with “resource://”, embedded GResources will be used to locate the theme files. Otherwise, resource_path is expected to be a path on disk that may or may not exist.

If the resource_path contains a directory named “themes”, that directory will be traversed for files matching the theme name and variant. For example, if using the Adwaita theme, “themes/Adwaita.css” will be loaded. If the dark variant is being used, “themes/Adwaita-dark.css” will be loaeded. If no matching theme file is located, “themes/shared.css” will be loaded.

When the current theme changes, the CSS will be reloaded to adapt.

The “icons” sub-directory will be used to locate icon themes.

resource_path

A path to a GResources directory

pub fn remove_resources(&self, resource_path: &str)

This removes the CSS providers that were registered using resource_path.

You must have previously called add_resources() for this function to do anything.

Since icons cannot be unloaded, previously loaded icons will continue to be available even after calling this function.

resource_path

A previously registered resources path

impl ParentClassIs for ThemeManager

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for ThemeManager

fn eq(&self, other: &OT) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for ThemeManager

fn static_type() -> Type

Returns the type identifier of Self.
