[Qt-interest] Segmentation fault with QList of pointers in thread

[Donal]

Just as I got this email I noticed where I was going wrong.
It was quite a stupid mistake really, as matter of a fact, really stupid.

I was creating a Class that was local to a function and sending this to the
thread and starting it within this function.
By time thread came around again after a sleep the data that was in the
function was destroyed so pointer pointing to invalid memory.

I'm a bit out of programming practice, not good time with my final year
project and all!

Thanks very much for the reply.

Regards,
Donal
