[Interest] QLabel inconsistent sizing with word wrap

[Tony Rietwyk]

Hi Everybody. 

In my Qt 4.8.6 application I cannot understand why this QLabel widget's
sizing varies wildly depending on the text content - even for similar text!
The QLabel has only WordWrap switched on, and Alignment Top/Left.  All of
the widgets shown have size policy Preferred, except for the top level with
the black border that has horizontal and vertical both set to
MinimumExpanding.  I've checked the source records and both descriptions are
plain text without any line breaks, etc.  

There are lots of hits when googling, but few answers. 

Can anyone shed light on this?  Has the text layout code been improved in
v5?  

Regards, 

Tony
