Example of clipped description with Breeze style
QCommandLinkButton (from Qt 5 at least) uses font size 9pt for the title
(unless Vista style is used) and the description. In particular, this hardcoded
font size is used for calculating the size hints. The Breeze style paints title
and description with the button font without adjusting the font size. Depending
on the length of the text and the width of the button (i.e. if the description
fits in two lines with 9pt, but needs three lines with the normal font size)
this causes clipping of the description.
Unfortunately, QCommandLinkButton hardcodes the font used for title and
description. Moreover, it hides this implementation detail in the cpp file.
Breeze either needs to make use of QCommandLinkButton's paintEvent or it needs
to copy QCommandLinkButtonPrivate::titleFont() and ::descriptionFont() to use
the correct font for painting. Simply using a larger font because it matches
the Breeze style is no option unless you find a way to make the calculation of
the size hints match the sizes used for painting.
