Struct gtk::WindowGroup

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

A WindowGroup restricts the effect of grabs to windows in the same group, thereby making window groups almost behave like separate applications.

A window can be a member in at most one window group at a time. Windows that have not been explicitly assigned to a group are implicitly treated like windows of the default window group.

GtkWindowGroup objects are referenced by each window in the group, so once you have added all windows to a GtkWindowGroup, you can drop the initial reference to the window group with g_object_unref(). If the windows in the window group are subsequently destroyed, then they will be removed from the window group and drop their references on the window group; when all window have been removed, the window group will be freed.

Implementations

impl WindowGroup

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

pub fn new() -> WindowGroup

Creates a new WindowGroup object. Grabs added with WidgetExt::grab_add() only affect windows within the same WindowGroup.

Returns

a new WindowGroup.

Trait Implementations

impl Clone for WindowGroup

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 WindowGroup

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

Formats the value using the given formatter.

impl Default for WindowGroup

fn default() -> Self

Returns the “default value” for a type.

impl Display for WindowGroup

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

Formats the value using the given formatter.

impl Hash for WindowGroup

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,

Feeds a slice of this type into the given Hasher.

impl Ord for WindowGroup

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

type Parent = Object

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

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

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

fn static_type() -> Type

Returns the type identifier of Self.
