Why Slot is not getting called when timer is timeout

[ndiwan]

m_Timer=new QTimer();
m_Timer->setInterval(1000);
connect(m_Timer, SIGNAL(timeout()), this, SLOT(flashColor()));

void CIndicator::setBIsFlash(bool bIsFlash)
{
m_bIsFlash = bIsFlash;
if(m_bIsFlash)
{
m_Timer->start();
}
else
{
m_Timer->stop();
}
}

void CIndicator::flashColor()
{
if(getQcIndicatorColor() != getQcIndicatorFlashColor())
{
setQcIndicatorColor(getQcIndicatorFlashColor());
}
else
{
setQcIndicatorColor(getQcIndicatorColorBKP());
}
}

I am sure than timer is starting

@ndiwan And are you equally sure your slot is not getting called?

[ndiwan]

@JonB yes I put a debug point on timer start and slot function. I am getting up to timer start, but then its not calling slot.

@JonB I would guess the slot is not declared as such so it's not found during runtime. That's the price to pay by not using the pmf syntax nowadays...

I have never used them, would that not produce some runtime warning message?
I think the runtime connect() would at least return that error condition?

It will but only if you look at the console...🙂

@JonB I just noticed that SLOT fnction is getting called but just once in a while, like once in 1.5 mints. But I set the timer to 1000 ms

@ndiwan

So something else must be blocking the execution.
Strip your app down to just the timer and color function and see if it works

How did you notice that? Did you put in debug statement or rely on seeing the color change?

Otherwise if this is not your whole program then follow @Pl45m4's advice.

@JonB I added a debug point.
