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.
static GType Gtk::CssProvider::get_type |
( |
| ) |
|
|
static |
Get the GType for this class, for use with the underlying GObject type system.
GtkCssProvider* Gtk::CssProvider::gobj |
( |
| ) |
|
|
inline |
Provides access to the underlying C GObject.
const GtkCssProvider* Gtk::CssProvider::gobj |
( |
| ) |
const |
|
inline |
Provides access to the underlying C GObject.
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 Gtk::CssProvider::signal_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 Gtk::CssProvider::signal_parsing_error() signal.
void Gtk::CssProvider::load_from_resource |
( |
const std::string & |
resource_path | ) |
|
- Parameters
-
- Slot Prototype:
void on_my_parsing_error(const Glib::RefPtr<const CssSection>& section, const Glib::Error& error)
Signals that a parsing error occured. 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.
- Parameters
-
section | Section the error happened in. |
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.
