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.
- Since gtkmm 3.0:
virtual Gtk::CssProvider::~CssProvider |
( |
) | |
|
|
virtual |
Gtk::CssProvider::CssProvider |
( |
) | |
|
|
protected |
Returns the provider containing the style settings used as a fallback for all widgets.
- Returns
- The provider used for fallback styling. This memory is owned by GTK+, and you must not free it.
Loads a theme from the usual theme paths.
- Parameters
-
name | A theme name. |
variant | Variant to load, for example, "dark", or 0 for the default. |
- Returns
- A Gtk::CssProvider with the theme loaded. This memory is owned by GTK+, and you must not free it.

Get the GType for this class, for use with the underlying GObject type system.
GtkCssProvider* Gtk::CssProvider::gobj |

Provides access to the underlying C GObject.
const GtkCssProvider* Gtk::CssProvider::gobj |

const |

GtkCssProvider* Gtk::CssProvider::gobj_copy |
( |
) | |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
bool Gtk::CssProvider::load_from_data |
( |
const std::string & |
data) | |
|
Loads data into this css provider, making it clear any previously loaded information.
- Parameters
-
data | CSS data loaded in memory. |
- Returns
- True if the data could be loaded.
Loads the data contained in file into css_provider, making it clear any previously loaded information.
- Parameters
-
file | File pointing to a file to load. |
- Returns
true
. The return value is deprecated and false
will only be returned for backwards compatibility reasons if an error is not 0
and a loading error occured. To track errors while loading CSS, connect to the GtkCssProvider::parsing-error signal.
bool Gtk::CssProvider::load_from_path |
( |
const std::string & |
path) | |
|
Loads the data contained in path into css_provider, making it clear any previously loaded information.
- Parameters
-
path | The path of a filename to load, in the GLib filename encoding. |
- Returns
true
. The return value is deprecated and false
will only be returned for backwards compatibility reasons if an error is not 0
and a loading error occured. To track errors while loading CSS, connect to the GtkCssProvider::parsing-error signal.
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.
- Since gtkmm 3.2:
- Returns
- A new string representing the provider.
A Glib::wrap() method for this object.
- Parameters
-
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. |
- Returns
- A C++ instance that wraps this C instance.
