Struct gtk::TargetList

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

A TargetList-struct is a reference counted list of GtkTargetPair and should be treated as opaque.

Implementations

impl TargetList

pub fn as_ptr(&self) -> *mut GtkTargetList

impl TargetList

pub fn add(&self, target: &Atom, flags: u32, info: u32)

Appends another target to a TargetList.

target

the interned atom representing the target

flags

the flags for this target

info

an ID that will be passed back to the application

pub fn add_image_targets(&self, info: u32, writable: bool)

Appends the image targets supported by SelectionData to the target list. All targets are added with the same info.

info

an ID that will be passed back to the application

writable

whether to add only targets for which GTK+ knows how to convert a pixbuf into the format

pub fn add_rich_text_targets(
    &self,
    info: u32,
    deserializable: bool,
    buffer: &impl IsA<TextBuffer>
)

Appends the rich text targets registered with gtk_text_buffer_register_serialize_format() or gtk_text_buffer_register_deserialize_format() to the target list. All targets are added with the same info.

info

an ID that will be passed back to the application

deserializable

if true, then deserializable rich text formats will be added, serializable formats otherwise.

buffer

a TextBuffer.

pub fn add_text_targets(&self, info: u32)

Appends the text targets supported by SelectionData to the target list. All targets are added with the same info.

info

an ID that will be passed back to the application

pub fn add_uri_targets(&self, info: u32)

Appends the URI targets supported by SelectionData to the target list. All targets are added with the same info.

info

an ID that will be passed back to the application

pub fn find(&self, target: &Atom) -> Option<u32>

Looks up a given target in a TargetList.

target

an interned atom representing the target to search for

Returns

true if the target was found, otherwise false

info

a pointer to the location to store application info for target, or None

pub fn remove(&self, target: &Atom)

Removes a target from a target list.

target

the interned atom representing the target

impl TargetList

pub fn new(targets: &[TargetEntry]) -> Self

Creates a new TargetList from an array of TargetEntry.

targets

Pointer to an array of TargetEntry

Returns

the new TargetList.

Trait Implementations

impl Clone for TargetList

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TargetList

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

Formats the value using the given formatter.

impl Hash for TargetList

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,

Feeds a slice of this type into the given Hasher.

impl Ord for TargetList

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

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<TargetList> for TargetList

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

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

const 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<TargetList> for TargetList

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

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

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

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

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

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

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

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

const 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 TargetList

fn static_type() -> Type

Returns the type identifier of Self.
