using ui in application

[fareenafatima]

if anyone wants to include its ui file in the code, then there are three approaches to it.
1) direct
2)single inheritance
3) multiple inheritance

can u tell of any link that can demonstrate the second and third approach.

In this (http://doc.qt.nokia.com/4.7/designer-using-a-ui-file.html) page are explained all three ways to achieve that.
