efl.ecore.Timer
Class¶
- class efl.ecore.Timer(double interval, func, *args, **kargs)¶
Bases:
efl.eo.Eo
Creates a timer to call the given function in the given period of time.
This class represents a timer that will call the given
func
everyinterval
seconds. The function will be passed any extra parameters given to constructor.When the timer
func
is called, it must return a value of either True or False (remember that Python returns None if no value is explicitly returned and None evaluates to False). If it returns True, it will be called again at the next interval, or if it returns False it will be deleted automatically making any references/handles for it invalid.Timers should be stopped/deleted by means of
delete()
or returning False fromfunc
, otherwise they’ll continue alive, even if the current python context delete it’s reference to it.For convenience and readability callback can also return one of the Callback return values. That is
ECORE_CALLBACK_RENEW
(like returning True) orECORE_CALLBACK_CANCEL
(like returning False).- Parameters
interval (float) – interval in seconds.
func (callable) – function to callback when timer expires.
*args – All the remaining arguments will be passed back in the callback function.
**kwargs – All the remaining keyword arguments will be passed back in the callback function.
Expected func signature:
func(*args, **kargs): bool
- delay(add)¶
Delay the execution of the timer by the given amount
- Parameters
add (double) – seconds to add to the timer

- interval¶
The interval (in seconds) between each call of the timer
- Type

- interval_get()¶
- interval_set(t)¶
- pending¶

New in version 1.8.
- pending_get()¶
- reset()¶
Reset the counter of the timer
New in version 1.8.
- stop()¶
Alias for
