threading

Hi,

I am writing a sample which uses thread to do some background processing.

In the thread I am trying to emitting a signal. But it is not coming to slot.

While connecting I checked the value of “connect()” function value , it is returning value as true.

One thing to notice is in the run method I am not using “exec() “ .

Please help me to solve this problem.
