QTimer

[benjiii]

Hi

Is it necessary to delete timer object after use in destructor.

@
//constructor--
Class1::Class1()
{
pTimer = new QTimer();
........
.........
pTimer->start(1000);
}

//destructor
Class1::~Class1()
{
delete pTimer;
}

@

Thanks

Hello.
Timer constructor: QTimer::QTimer (QObject * parent = 0);
Use parent parameter and your class will automatically delete timer.
@
//constructor--
Class1::Class1()
{
pTimer = new QTimer(this);
........
.........
pTimer->start(1000);
}

It works If your class inherits from QObject. If not, then delete it in destructor.

Also you can use member timer rather than pointer.
@
// header
class Class1 {
public:
Class1();
~Class1();
private:
QTimer timer_;
};

// cpp
Class1::Class1() : timer_()
{
...
...
timer_.start(1000);
};
