# Description

`CssProvider` is an object implementing the `StyleProvider` interface. It is able to parse CSS-like input in order to style widgets.

# Constructors

cssProviderNew

Arguments

:: IO CssProvider | A new CssProvider

Returns a newly created CssProvider

# Methods

cssProviderGetDefault

Arguments

:: IO CssProvider | The provider used for fallback styling

Returns the provider containing the style settings used as a fallback for all widgets.

cssProviderGetNamed

Arguments

:: GlibString string |
=> string | `name` : A theme name
-> Maybe string | `variant` to load, for example, "dark"
-> IO (Maybe CssProvider) | a `CssProvider` with the theme loaded

Loads a theme from the usual theme paths

cssProviderLoadFromData

Arguments

:: CssProviderClass cssProvider |
=> cssProvider | `cssProvider` : a `CssProvider`
-> Ptr CChar | `_data` : CSS data loaded in memory. [array length=length][element-type guint8]
-> Int | `length` : the length of `_data` in bytes, or -1 for NUL terminated strings. If `length` is not -1, the code will assume it is not NUL terminated and will potentially do a copy.
-> IO () |

Loads `_data` into `cssProvider`, making it clear any previously loaded information.

cssProviderLoadFromString

Arguments

:: (CssProviderClass cssProvider, GlibString string) |
=> cssProvider | `cssProvider` : a `CssProvider`
-> string | `css` : CSS data loaded in memory.
-> IO () |

Loads `css` into `cssProvider`, making it clear any previously loaded information.

cssProviderLoadFromPath

Arguments

:: (CssProviderClass cssProvider, GlibFilePath fp) |
=> cssProvider | `cssProvider` a `CssProvider`
-> fp | the path of a filename to load
-> IO () |

Loads the data contained in `path` into `cssProvider`, making it clear any previously loaded information

cssProviderToString

Arguments

:: (CssProviderClass cssProvider, GlibString string) |
=> cssProvider | `provider` a `CssProvider`
-> IO string |

Convertes the `provider` into a string representation in CSS format.

Using `cssProviderLoadFromString` with the return value from this function on a new provider created with `cssProviderNew` will basically create a duplicate of this `provider`.
