Problem with QTimer

[bluefly]

And if you derive your class A from some other class B, you should call B's constructor in A():

MyObject::MyObject()
   : QObject()
{
....
}

MyObject::MyObject()
   : QObject()
{
....
}

actually that happens implicitly. if you want to call a non default base class constructor, you have to say so explicitly using that syntax.
