Struct gtk4::WindowGroup

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

WindowGroup makes group of windows behave like separate applications.

It achieves this by limiting the effect of GTK grabs and modality to windows in the same group.

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.

WindowGroup objects are referenced by each window in the group, so once you have added all windows to a WindowGroup, 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.

Modality of windows only affects windows within the same WindowGroup.

Returns

a new WindowGroup.

Trait Implementations

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 HasParamSpec for WindowGroup

type ParamSpec = ParamSpecObject

type SetValue = WindowGroup

Preferred value to be used as setter for the associated ParamSpec.

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: WindowGroupImpl> IsSubclassable<T> for WindowGroup

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 WindowGroup

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.

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 ==.

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.

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.

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 WindowGroup

fn static_type() -> Type

Returns the type identifier of Self.
