typedef void(*)(gpointer data | DestroyNotify) |
CSS-like styling for widgets, implementing the StyleProvider base class.
It is able to parse CSS-like input in order to style widgets.
An application can cause GTK+ to parse a specific CSS style sheet by calling load_from_file() and adding the provider with StyleContext::add_provider() or StyleContext::add_provider_for_screen(). In addition, certain files will be read when GTK+ is initialized. See the GtkCssProvider documentation for details of these default files and details of the stylesheets.

void on_my_parsing_error(const Glib::RefPtr<const CssSection>& section, const Glib::Error& error)
Flags: Run Last
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.
section | Section the error happened in. |
Glib::ustring Gtk::CssProvider::to_string | ( | ) | const |
Converts the provider into a string representation in CSS format.
Using load_from_data() with the return value from this function on a new provider created with new() will basically create a duplicate of this provider.

object | The C instance. |
take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
