Should be QHBoxLayout, but this is probably obvious ;-)

You can even make use of the fact that Qt auto-deletes child objects, so you 
don't have to keep the layout in a variable unless you want to use it more 
than once:

( new QHBoxLayout( ptr_priority ) )->setAutoAdd( true );

I guess some people consider this ugly coding, though I personally find it 
very useful to distinguish between dummy objects that are created and 
forgotten (not assigned to a var at all), class members (m_xxxx naming) and 
other local objects that are used in a method, but not afterwards ('normal' 
var naming). I know from the IRC channel that at least Charles uses this 
technique as well.
