free/delete calls

[jcoop]

Is there any special call that needs to be done to free up space used by QT objects? For instance, if I'm using CV and I create a CVImage, it has to be deleted with the line, "cvReleaseImage()," rather than a standard "free" or "delete" type of call. Is that true of anything in QT?

Object trees - read the section about object construction/destruction order, especially the first paragraph.
