[docs]class Timer(QtCore.QTimer): """A wrapper class over the :class:`QtCore.QTimer`. The Timer waits a given amount of time and then executes some code. Parameters ---------- sec: float Time in seconds to wait before running *func*. func: callable Function to execute after *sec* seconds. repeat: bool If True, the execution of *func* will be repeated every *sec* seconds. The default is to execute only once. start: bool If True (default), the Timer is started immediately when created. It may be set to False to create a Timer that will be started later. Notes ----- Keep the Timer bound to a variable, so that it is not destroyed before it has executed. QTimer methods like start, stop can be used to (re)start or stop an existing Timer.
