wx.CallLater

A convenience class for wx.Timer, that calls the given callable object once after the given amount of milliseconds, passing any positional or keyword args. The return value of the callable is available after it has been run with the GetResult method.

If you don’t need to get the return value or restart the timer then there is no need to hold a reference to this object. CallLater maintains references to its instances while they are running. When they finish, the internal reference is deleted and the GC is free to collect naturally.

Methods

__init__(self, millis, callableObj: Callable[_P, _T], *args: _P.args, **kwargs: _P.kwargs)

Constructs a new wx.CallLater object.

Parameters:

• millis (int) – number of milliseconds to delay until calling the callable object

• callableObj (PyObject) – the callable object

• args – arguments to be passed to the callable object

• kw – keyword arguments to be passed to the callable object

---

GetInterval(self)

---

GetResult(self)

Returns the value of the callable.

Return type:

a Python object

Returns:

result from callable

---

HasRun(self)

Returns whether or not the callable has run.

Return type:

bool

---

IsRunning(self)

---

Notify(self)

The timer has expired so call the callable.

---

SetArgs(self, *args: _P.args, **kwargs: _P.kwargs)

(Re)set the args passed to the callable object. This is useful in conjunction with Start if you want to schedule a new call to the same callable object but with different parameters.

Parameters:

• args – arguments to be passed to the callable object

• kw – keywords to be passed to the callable object

---

Start(self, millis: Optional[int] = None, *args: _P.args, **kwargs: _P.kwargs)

(Re)start the timer

Parameters:

• millis (int) – number of milli seconds

• args – arguments to be passed to the callable object

• kw – keywords to be passed to the callable object

---

Stop(self)

Stop and destroy the timer.

---

__del__(self)
