Memory-managed wrapper type.

Type class for types which can be safely cast to CssProvider, for instance with toCssProvider.

Cast to CssProvider, for types for which this is known to be safe. For general casts, use castTo.

Loads data into cssProvider, and by doing so clears any previously loaded information.

Loads the data contained in file into cssProvider, making it clear any previously loaded information.

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

Loads the data contained in the resource at resourcePath into the CssProvider, clearing any previously loaded information.

To track errors while loading CSS, connect to the parsingError signal.

Loads a theme from the usual theme paths. The actual process of finding the theme might change between releases, but it is guaranteed that this function uses the same mechanism to load the theme that GTK uses for loading its own theme.

Returns a newly created CssProvider.

Converts the provider into a string representation in CSS format.

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

Type for the callback on the (unwrapped) C side.

Signals that a parsing error occurred. the path, line and position describe the actual location of the error as accurately as possible.

Parsing errors are never fatal, so the parsing will resume after the error. Errors may however cause parts of the given data or even all of it to not be parsed at all. So it is a useful idea to check that the parsing succeeds by connecting to this signal.

Note that this signal may be emitted at any time as the css provider may opt to defer parsing parts or all of the input to a later time than when a loading function was called.

Connect a signal handler for the parsingError signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after cssProvider #parsingError callback

Wrap the callback into a GClosure.

Generate a function pointer callable from C code, from a C_CssProviderParsingErrorCallback.

A convenience synonym for Nothing :: Maybe CssProviderParsingErrorCallback.

Connect a signal handler for the parsingError signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on cssProvider #parsingError callback

Wrap a CssProviderParsingErrorCallback into a C_CssProviderParsingErrorCallback.
