How to use QTimer connect without Object and without slot

[mrudula]

Could you please share details on using connect function call without object and without slot.

When I am trying below connect call: where in i want to use QTimer without a class object and without slot
QObject::connect(pTimerUpdateScheduleTimeout, &QTimer::timeout,NULL, UpdateScheduleEvent());

I am getting below error:
error: invalid use of void expression
QObject::connect(pTimerValidateScheduleTimeout, &QTimer::timeout,NULL, ValidateScheduleEvent())

could you please help on above error.

Thanks,
Mrudula

ValidateScheduleEvent() calls the function and pass the result back to connect as an argument. what you want is taking the function pointer: QObject::connect(pTimerValidateScheduleTimeout, &QTimer::timeout,&ValidateScheduleEvent);

Hi,
You can use QTimer with lamda functions like this.

connect(pTimerValidateScheduleTimeoutr, &QTimer::timeout, []() {
ValidateScheduleEvent();
});
