[Qt-interest] Problem with getExistingDirectory....Please advise

[Usman Ajmal]

Ahaa...solved the problem. Now i have a very good idea of using SLOTS,
SIGNALS and multiple inheritance.

Bundles of thanks to Alexis who kinda daunt me to go through tutorials first
:) and to Octave who on one thread pasted link to Multiple Inheritance in
Qt, that saved me a lot of time. Thanks to Thiago and Srdjan too.
