emit not working in constructor

Consider the scenario:
I have 3 CLASS. 1st and 2nd CLASS can be accessed via 3rd CLASS..So i place a connect() inside 3rd CLASS connecting 1st CLASS signal() to 2nd CLASS slot().....But if i place my emit signal in 1st CLASS constructor, its not hitting the slot in 2nd CLASS....But in 1st CLASS, if i place a timer and in its timeout() i emit the signal then appropriate slot is called in 2nd CLASS...

I need to know the reason why emit is not valid inside 1st CLASS constructor....

NOTE: 2nd CLASS object is created before 1st CLASS..So there should not have been a problem with calling emit() from 1st CLASS constructor....

Show the code : crystal ball does not work.
PS.
To connect the signal to the slot you first need to create a sender and receiver objects. Thus, the emission signal in the constructor of the sender does not make any sense.

Its simple CLASS1 is not created when signal is emitted.Since you have given in constructor of CLASS1 it will not work.

Thank for the reply....I got it now.........
