I see - why don't you BYO. This kind of widget is uncommon, and thus the 
reason not being available already. 

But it's pretty easy to combine basic widgets to a composite one. And due to 
Qts powerful layout machinery, you mostly don't need to care about the 
implicit widget resize. 

Custom composite widgets have some pitfalls in the details, but just start 
over, we will help you getting through.
