Struct sdl2::event::EventWatch

source · [−]

pub struct EventWatch<'a, CB: EventWatchCallback + 'a> { /* private fields */ }

Expand description

An handler for the event watch callback. One must bind this struct in a variable as long as you want to keep the callback active. For further information, see [EventSubsystem::add_event_watch].

Implementations

source

impl<'a, CB: EventWatchCallback + 'a> EventWatch<'a, CB>

source

pub fn activate(&mut self)

Activates the event watch. Does nothing if it is already activated.

source

pub fn deactivate(&mut self)

Deactivates the event watch. Does nothing if it is already activated.

source

pub fn activated(&self) -> bool

Returns if the event watch is activated.

source

pub fn set_activated(&mut self, activate: bool)

Set the activation state of the event watch.
