Implementations§

Source§

impl MainLoop

Source

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

Return the inner pointer to the underlying C value.

Source

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

Borrows the underlying C value.

Source§

impl MainLoop

Source

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. 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.

Source

pub fn context(&self) -> MainContext

Returns the MainContext of @self.

§Returns

the MainContext of @self Returns the MainContext of @self.

§Returns

the MainContext of @self

Source

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

§Returns

true if the mainloop is currently being run.

Source

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. 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.

Source

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.

impl Clone for MainLoop

Source§

fn clone(&self) -> Self
