Description
Hello. I try detecting change state computer - hibernate/sleep mode
On Qt forum https://forum.qt.io/topic/69485/do-an-operation-when-computer-goes-to-sleep used nativeEventFilter from QAbstractNativeEventFilter.
I created example based on QCoreApplication:
{{}}
from PySide2.QtCore import QCoreApplication, QAbstractNativeEventFilter class MyFilter(QAbstractNativeEventFilter): def nativeEventFilter(eventType, message, result): print("eventType %s" % eventType) print("message %s" % message) print("result %s" % result) return False my_filter = MyFilter() app = QCoreApplication() event_dispatcher = app.eventDispatcher() print(event_dispatcher) event_dispatcher.installNativeEventFilter(my_filter) # app.installNativeEventFilter(my_filter) print("App started") app.exec_()
Ran this script on Fedora 32 (PySide2 - 5.15.0) - no events caught
Ran this script on Windows 10 (PySide2 - 5.14.2) - immediately after start recived only three event:
eventType <__main__.MyFilter object at 0x0000026E74140340> message b'windows_dispatcher_MSG' result shiboken2.libshiboken.VoidPtr(Address 0x00000075667EB830, Size 0, isWritable False) eventType <__main__.MyFilter object at 0x0000026E74140340> message b'windows_dispatcher_MSG' result shiboken2.libshiboken.VoidPtr(Address 0x00000075667EB840, Size 0, isWritable False) eventType <__main__.MyFilter object at 0x0000026E74140340> message b'windows_dispatcher_MSG' result shiboken2.libshiboken.VoidPtr(Address 0x00000075667EB760, Size 0, isWritable False)
