no, you have to explicitly delete memory allocated by new.

assuming you are referring to cachedContents[1], you may as well do it pointer 
there and just make sure to delete it in the dtor as you did.

the backgroundPixmap variable doesn't need to be stored outside of 
paintBackground in any case.


[1] which is a slightly confusing name given that elsewhere in the 
code "contents" refers to what the applet subclass paints in paintInterface 
and that we aren't actually caching those contents at all, but the background
