[Qt-interest] customised signals and slots in qt

[Sahana Bhaskar]

I see that in my case there is no .pro file. And also this class I am  talking about does not have a .moc file either. Is it necessary?  I added this class to my existing code. Do I need some steps to add .moc? as .moc usually gets added if you have an UI related to that class which is not relevant in this case.

Thanks,
Sahana
