Struct MainLoop

pub struct MainLoop { /* private fields */ }

The GMainLoop struct is an opaque data type representing the main event loop of a GLib or GTK application.

GLib type: Shared boxed type with reference counted clone semantics.

Implementations

impl MainLoop

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

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow(ptr: &*mut GMainLoop) -> &Self

Borrows the underlying C value.

impl MainLoop

pub fn new(context: Option<&MainContext>, is_running: bool) -> MainLoop

Creates a new MainLoop structure.

context

a #GMainContext (if None, the global-default main context will be used).

is_running

set to true to indicate that the loop is running. This is not very important since calling run() will set this to true anyway.

Returns

a new #GMainLoop.

pub fn context(&self) -> MainContext

Returns the MainContext of @self.

Returns

the MainContext of @self

pub fn is_running(&self) -> bool

Checks to see if the main loop is currently being run via run().

Returns

true if the mainloop is currently being run.

pub fn quit(&self)

Stops a MainLoop from running. Any calls to run() for the loop will return.

Note that sources that have already been dispatched when quit() is called will still be executed.

pub fn run(&self)

Runs a main loop until quit() is called on the loop. If this is called for the thread of the loop’s #GMainContext, it will process events from the loop, otherwise it will simply wait.

Trait Implementations

impl Clone for MainLoop

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the reference. Dropping the reference will decrement it again.

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

Performs copy-assignment from source.

impl Debug for MainLoop

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

Formats the value using the given formatter.

impl From<MainLoop> for Value

fn from(s: MainLoop) -> Self

Converts to this type from the input type.

impl HasParamSpec for MainLoop

type ParamSpec = ParamSpecBoxed

type SetValue = MainLoop

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

type BuilderFn = fn(_: &str) -> ParamSpecBoxedBuilder<'_, MainLoop>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for MainLoop

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 MainLoop

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MainLoop

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for MainLoop

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for MainLoop

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for MainLoop

impl Send for MainLoop

impl StructuralPartialEq for MainLoop

impl Sync for MainLoop
