Instance Method Details

Parameters:

  • data (Array<Integer>) —

    CSS data loaded in memory

  • length (Gtk::gssize) —

    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.

Returns:

  • (TrueClass) —

    true. The return value is deprecated and false will only be returned for backwards compatibility reasons if an error is not nil and a loading error occurred. To track errors while loading CSS, connect to the Gtk::CssProvider::parsing-error signal.

#load_from_file(file) ⇒ TrueClass

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

Parameters:

  • file (Gio::File) —

    #GFile pointing to a file to load

Returns:

  • (TrueClass) —

    true. The return value is deprecated and false will only be returned for backwards compatibility reasons if an error is not nil and a loading error occurred. To track errors while loading CSS, connect to the Gtk::CssProvider::parsing-error signal.

#load_from_path(path) ⇒ TrueClass

    the path of a filename to load, in the GLib filename encoding

Returns:

Returns:

#to_string ⇒ String

Converts the provider into a string representation in CSS format.

Returns:

  • (String) —

    a new string representing the provider.
