You are correct, which leaves me mystified. I thought that Cmd-Q or
clicking the red button on the window would automatically force a call
to dealloc. Clearly this is not the case. Can anyone clear up my
confusion.

I don't think C++ memory management has anything to do with this --
could it be that your QuartzView object's -dealloc: is never getting
called, so the C++ object doesn't free? You might have to close your
window explicitly.

I have a pointer to a C++ object within my ObjC class:
@interface QuartzView : NSView {
BitMapMgr * pbmp;
}
@end
I have done the following to manage the object:
- (id)initWithFrame:(NSRect)frame {
self = [super initWithFrame:frame];
if (self) {
pbmp = new BitMapMgr; // Call the constructor
}
return self;
}
- (void)dealloc {
delete pbmp; // Call the destructor
}
However, when I run the application within Xcode print statements
confirm that only the constructor gets called. What is the correct
way to release the memory allocated for pbmp?
Thanks,
Garvin.
