QT Timer Timeout

Ayush Gupta

I am trying to execute below code

QTimer test;
QObject::connect(test, SIGNAL(timeout()), this, SLOT(testSlot()));

test->start(3000);

I want that my slot should execute immediately after start then after 3000ms it should execute.
But currently what is happening slot is executing after 3000ms.

Is there any way to solve it ?

I don't understand this. Your code is doing exactly what you asked it to do: call slot after 3000ms timeout. So, what do you want to do? Do you want to execute it after test->start(3000); and then second time after 3000ms timeout? if so, why not simply:

QTimer test;
QObject::connect(test, SIGNAL(timeout()), this, SLOT(testSlot()));

test->start(3000);
testSlot();

?
