Struct gtk4::CssSection

#[repr(transparent)]
pub struct CssSection { /* private fields */ }

Defines a part of a CSS document.

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

Implementations

impl CssSection

pub fn new( file: Option<&impl IsA<File>>, start: &CssLocation, end: &CssLocation ) -> CssSection

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

file

The file this section refers to

start

The start location

end

The end location

Returns

a new CssSection

pub fn end_location(&self) -> CssLocation

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

Returns

The end location of this section

pub fn file(&self) -> Option<File>

Gets the file that @self was parsed from.

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

Returns

the GFile from which the section was parsed

pub fn parent(&self) -> Option<CssSection>

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_CSS_SECTION_DOCUMENT. Their parent will either be NULL if they are the original CSS document that was loaded by CssProvider::load_from_file() or a section of type GTK_CSS_SECTION_IMPORT if it was loaded with an @import rule from a different file.

Returns

the parent section

pub fn start_location(&self) -> CssLocation

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

Returns

The start location of this section

pub fn to_str(&self) -> GString

Prints the section into a human-readable text form using Gtk::CssSection::print().

Returns

A new string.

Trait Implementations

impl Clone for CssSection

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CssSection

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for CssSection

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for CssSection

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for CssSection

fn cmp(&self, other: &CssSection) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<CssSection> for CssSection

fn eq(&self, other: &CssSection) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<CssSection> for CssSection

fn partial_cmp(&self, other: &CssSection) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for CssSection

fn static_type() -> Type

Returns the type identifier of Self.
