[Qt-interest] set QListWidget's sizeHint() to fit contents

[Serge]

Hi,

I have QListWidget's descendant with constant 3 rows. I need to define 
its size so that it would not need vertical scroll bar and at the same 
time there would be no free space under last row. In other word i need 
to fit height of QListWidget to height of its contents. How can i detect 
height of contents in code of sizeHint() procedure?
