This module provides convenience functions for starting and stopping a QTimer that will monitor "queued" signals and invoke their callbacks. This is useful when psygnal is used in a Qt application, and you'd like to emit signals from a thread but have their callbacks invoked in the main thread. é)Úannotations)ÚThreadÚcurrent_threadé)Úemit_queued)ÚQtÚQTimerzGThe psygnal.qt module requires qtpy and some Qt backend to be installedNzdict[Thread, QTimer]Ú_TIMERSÚmsecÚintÚ timer_typeúQt.TimerTypeÚthreadú Thread | NoneÚreturnÚNonecCsr|durtƒn|}|tvrtƒt|<t|j t¡t| |¡t| ¡r0t| |¡dSt| |¡dS)aÊStart a QTimer that will monitor the global emission queue. If a QTimer is already running in the current thread, then this function will update the interval and timer type of that QTimer. (It is safe to call this function multiple times in the same thread.) When callbacks are connected to signals with `connect(type='queued')`, then they are not invoked immediately, but rather added to a global queue. This function starts a QTimer that will periodically check the queue and invoke any callbacks that are waiting to be invoked (in whatever thread this QTimer is running in). Parameters ---------- msec : int, optional The interval (in milliseconds) at which the QTimer will check the global emission queue. By default, the QTimer will check the queue as often as possible (i.e. 0 milliseconds). timer_type : Qt.TimerType, optional The type of timer to use. By default, Qt.PreciseTimer is used, which is the most accurate timer available on the system. thread : Thread, optional The thread in which to start the QTimer. By default, the QTimer will be started in the thread from which this function is called.
