Detailed Description

Defines a part of a CSS document.

Because sections are nested into one another, you can use get_parent() to get the containing region.

A CssSection is input data to a Gtk::CssProvider::signal_parsing_error() handler.

Since gtkmm 3.16:

Member Function Documentation

create()

static Glib::RefPtr< CssSection > Gtk::CssSection::create ( const Glib::RefPtr< Gio::File > &  file, const CssLocation &  start, const CssLocation &  end  )

static

Creates a new Gtk::CssSection referring to the section in the given file from the start location to the end location.

Parameters

file	The file this section refers to.
start	The start location.
end	The end location.

Returns

A new Gtk::CssSection.

get_end_location()

CssLocation Gtk::CssSection::get_end_location

(

)

const

Returns the location in the CSS document where this section ends.

Returns

The end location of this section.

get_file() [1/2]

Glib::RefPtr< Gio::File > Gtk::CssSection::get_file

(

)

Gets the file that section was parsed from.

If no such file exists, for example because the CSS was loaded via Gtk::CssProvider::load_from_data(), then nullptr is returned.

Returns

The Gio::File from which the section was parsed.

get_file() [2/2]

Glib::RefPtr< const Gio::File > Gtk::CssSection::get_file

(

)

const

Gets the file that section was parsed from.

If no such file exists, for example because the CSS was loaded via Gtk::CssProvider::load_from_data(), then nullptr is returned.

Returns

The Gio::File from which the section was parsed.

get_parent() [1/2]

Glib::RefPtr< CssSection > Gtk::CssSection::get_parent

(

)

Gets the parent section for the given section.

The parent section is the section that contains this section. A special case are sections of type Gtk::CssSection::Type::DOCUMENT. Their parent will either be nullptr if they are the original CSS document that was loaded by Gtk::CssProvider::load_from_file() or a section of type Gtk::CssSection::Type::IMPORT if it was loaded with an @a import rule from a different file.

Returns

The parent section.

get_parent() [2/2]

Glib::RefPtr< const CssSection > Gtk::CssSection::get_parent

(

)

const

Gets the parent section for the given section.

The parent section is the section that contains this section. A special case are sections of type Gtk::CssSection::Type::DOCUMENT. Their parent will either be nullptr if they are the original CSS document that was loaded by Gtk::CssProvider::load_from_file() or a section of type Gtk::CssSection::Type::IMPORT if it was loaded with an @a import rule from a different file.

Returns

The parent section.

get_start_location()

CssLocation Gtk::CssSection::get_start_location

(

)

const

Returns the location in the CSS document where this section starts.

Returns

The start location of this section.

gobj() [1/2]

GtkCssSection * Gtk::CssSection::gobj

(

)

Provides access to the underlying C instance.

gobj() [2/2]

const GtkCssSection * Gtk::CssSection::gobj

(

)

const

Provides access to the underlying C instance.

gobj_copy()

GtkCssSection * Gtk::CssSection::gobj_copy

(

)

const

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

operator delete()

void Gtk::CssSection::operator delete ( void *  , std::size_t    )

protected

operator=()

CssSection & Gtk::CssSection::operator= ( const CssSection &  )

delete

reference()

void Gtk::CssSection::reference

(

)

const

Increment the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

to_string()

Glib::ustring Gtk::CssSection::to_string

(

)

const

Prints the section into a human-readable text form.

This is a form like gtk.css:32:1-23 to denote line 32, characters 1 to 23 in the file gtk.css.

Returns

A new string.

unreference()

void Gtk::CssSection::unreference

(

)

const

Decrement the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

wrap()

Glib::RefPtr< Gtk::CssSection > wrap ( GtkCssSection *  object, bool  take_copy = false  )

related

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.
