Multiple lines and custom renderers

Message 1 in thread

Hi,

Is it possible to reder custom graphics and multiple lines for each
element in a QListWidget, for instance by using HTML ?

Hi Børge,

To do some custom rendering in an abstract item view you typically 
reimplement a custom delegate:

I would suggest you reimplement the sizeHint() and the paint() functions 
and use a QTextDocument internally to do the calculation of the size and 
do the painting.
