The documentation for the pprint module mentions that the method PrettyPrinter.format is intended to make it possible to customize formatting. I gather that it's possible to override this method in a subclass, but this doesn't seem to provide a way to have the base class methods apply line wrapping and indentation. Am I missing somethi...

Hi, This is probably asked before but I have no idea what to search for. This is my hierarchy now: NSObject > FirstSubclass > SecondSubclass. But I'm going to implement a new feature in my app which requires changing a few details in FirstSubclass when a certain condition is met. So actually I would need a subclass between FirstSubclass...

Can I have a class that extends View and implements SurfaceHolder.Callback and inside this class have a SurfaceView object? If this is possible, then I’d have to call on the SurfaceView constructor like this: SurfaceView sview = SurfaceView(this) inside the constructor of View’s subclass.

I want to be able to create an instance of a parent class X, with a string "Q" as an extra argument. This string is to be a name being an identifier for a subclass Q of the parent class X. I want the instance of the parent class to become (or be replaced with) an instance of the subclass. I am aware that this is probably a classic pro...
I want to have a static method in a parent class that creates instances of whatever subclass i call this method on.

The controller passes the right variables to the class, while the function build_afflink() selects what class ...
I am a little stumped as to how to instruct a programmatically created NSSegmentedControl to use a subclass instance of an NSSegmentedCell. If I want to use a subclasses NSSegmentedCell on an NSSegmentedControl built using IB it would be as simple as doing the following: Drag an NSSegmentedControl into the NSView Click through to the ...
Hi! I try to load an entity with some details and there is a resellerId in the entity. Now I inherit a subclass from it, and try to access the resellerId but it's not there.
