• Ways to make (relatively) safe assumptions about the type of concrete subclasses?

  - by Kylotan

  I have an interface (defined as a abstract base class) that looks like this: class AbstractInterface { public: bool IsRelatedTo(const AbstractInterface& other) const = 0; } And I have an implementation of this (constructors etc omitted): class ConcreteThing { public: bool IsRelatedTo(const AbstractInterface& other) const { return m_ImplObject.has_relationship_to(other.m_ImplObject); } private: ImplementationObject m_ImplObject; } The AbstractInterface forms an interface in Project A, and the ConcreteThing lives in Project B as an implementation of that interface. This is so that code in Project A can access data from Project B without having a direct dependency on it - Project B just has to implement the correct interface. Obviously the line in the body of the IsRelatedTo function cannot compile - that instance of ConcreteThing has an m_ImplObject member, but it can't assume that all AbstractInterfaces do, including the other argument. In my system, I can actually assume that all implementations of AbstractInterface are instances of ConcreteThing (or subclasses thereof), but I'd prefer not to be casting the object to the concrete type in order to get at the private member, or encoding that assumption in a way that will crash without a diagnostic later if this assumption ceases to hold true. I cannot modify ImplementationObject, but I can modify AbstractInterface and ConcreteThing. I also cannot use the standard RTTI mechanism for checking a type prior to casting, or use dynamic_cast for a similar purpose. I have a feeling that I might be able to overload IsRelatedTo with a ConcreteThing argument, but I'm not sure how to call it via the base IsRelatedTo(AbstractInterface) method. It wouldn't get called automatically as it's not a strict reimplementation of that method. Is there a pattern for doing what I want here, allowing me to implement the IsRelatedTo function via ImplementationObject::has_relationship_to(ImplementationObject), without risky casts? (Also, I couldn't think of a good question title - please change it if you have a better one.)

• How to have CVS files in different directory than source files in NetBeans?

  - by Ondrej Slinták

  I have a project in NetBeans which haven't used CVS until now. Let's say the directory with source files is called /www/source_files and directory with project files /www/project_files. Module in repository is called differently than source files directory. When I'm trying to check out CVS, it forces me to create a directory called exactly how module is called, which is fine by me in fact. Straight after it asks me if I wanted to create new project. And here the problem begins. I don't want to do that and I have no idea how to link newly created directory with CVS and checked out files with my project. I'd like to end up with following structure: /www /source_files /project_files /cvs_files Any ideas how to do this? I'm using NetBeans 6.8.

• Samsung TV Emulator font size

  - by jperovic

  Can someone please help me with this issue. I've been banging my head to find the solution but no help... The problem is that Samsung TV Emulator displays everything enlarged (line font-size 30ish pixels) and there does seem to have a way to override it. This only happens within Samsung UI components. To make sure it wasn't something with my project I've downloaded sample project from Brightcove: Sample project but noticed the same behavior with that as well. Here is the screenshot of my "project". It only one scene with two UI components: http://tinypic.com/r/124evqc/6 Opposed to that, here's what I see in my IDE view: http://tinypic.com/r/ezmn4l/6. As a side-note, I had to put height: 20px in both of my UI components' CSS in order for IDE to show them that way. Can anyone suggest what am I supposed to do?
