Struct gtk4::TextBuffer

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

Stores text and attributes for display in a TextView.

You may wish to begin by reading the text widget conceptual overview, which gives an overview of all the objects and data types related to the text widget and how they work together.

GtkTextBuffer can support undoing changes to the buffer content, see TextBufferExt::set_enable_undo().

Implementations

impl TextBuffer

pub const NONE: Option<&'static TextBuffer> = None

pub fn new(table: Option<&TextTagTable>) -> TextBuffer

Creates a new text buffer.

table

a tag table, or None to create a new one

Returns

a new text buffer

pub fn builder() -> TextBufferBuilder

Creates a new builder-pattern struct instance to construct TextBuffer objects.

This method returns an instance of TextBufferBuilder which can be used to create TextBuffer objects.

Trait Implementations

impl Clone for TextBuffer

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 TextBuffer

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

Formats the value using the given formatter.

impl Default for TextBuffer

fn default() -> Self

Returns the “default value” for a type.

impl Display for TextBuffer

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

Formats the value using the given formatter.

impl Hash for TextBuffer

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

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<T: TextBufferImpl> IsSubclassable<T> for TextBuffer

fn class_init(class: &mut Class<Self>)

Override the virtual methods of this class for the given subclass and do other class initialization.

fn instance_init(instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for TextBuffer

fn cmp(&self, other: &Self) -> 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 ParentClassIs for TextBuffer

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for TextBuffer

fn eq(&self, other: &OT) -> 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<OT: ObjectType> PartialOrd<OT> for TextBuffer

fn partial_cmp(&self, other: &OT) -> 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 TextBuffer

fn static_type() -> Type

Returns the type identifier of Self.
