I have a homework assignment that's really baking my noodle. It involves an elevator simulation that takes user inputs for the number of floors and the number of people using the elevator. the people's starting floor and destination floors are random numbers within the floors. I realize that my code is very sparse and that there's qui...
They say that eval() is evil. I want to avoid the use of the eval() line using proper PHP5 functionality. Given a class name in a static class method, how do I make it return a real object? class Model { public static function loadModel($sModelPath) { if (!(strpos(' ' . $sModelPath, '/')>0)) { $sModelPath .= '/' . $sModelPat...
I have a set of static class methods. I also have an existing database connection in a script stored in an object variable $DB. How do I call those static class methods and let them use that $DB object without having to pass them this variable every time as a parameter on the class method? For instance, right now I'm having to use a glo...
I am looking for pointers, suggestions, links, warnings, ideas and even anecdotical accounts about "how to design an application in a modular way". I am going to use python for this project, but advice does not need to necessarily refer to this language, although I am only willing to implement a design based on OOP. Here's some context ...

I am trying to achieve Model-view separation. My airplane is a class. While developing the application, can't I use the console as sort of viewer. Can I spawn the airplane on it's own thread, while the console makes references to the airplane object to retrieve/read it's current altitude. I am trying to make the airplane an Active object...
A long time ago I have read an article (I believe a blog entry) which put me on the "right" track on naming objects: Be very very scrupulous about naming things in your program. For example if my application was (as a typical business app) handling users, companies and addresses I'd have a User, a Company and an Address domain class - a...

Hi Guys, I do not know why I want to get or make this, a relational database contains all entities in the world, or an object-oriented set of classes, structs, interfaces.. etc for EVERYTHING in the world! Do you know where I can find something like this? ...
Is it possible, when instantiating an object, to pass-in a class which the object should derive from? For instance: class Red(object): def x(self): print '#F00' class Blue(object): def x(self): print '#00F' class Circle(object): def __init__(self, parent): # here, we set Bar's parent to `parent` ...
Imagine the following situation: As may notice the Handler-childs and the Costumer-childs match each other. Each Handler has a method that takes a costumer. Is there any good way true oo-ish to make sure that a Handler-implementation only takes a correponding Costumer-implementation or any childs of it? Some examples: Handler will...
Is it possible to override jQuerys target in a custom event? f.ex: var scope = function() { this.param = 'foo'; } var instance = new scope(); $(instance).bind('bar', function(e) { console.log(e.target); }); $(instance).trigger('bar'); This outputs the entire instance object, as it should. But if I want target to be someth...
I would like to create a descendant of the Silverlight Navigation Framework's Page class, so I can perform common navigation code on all of my pages, but I can't figure out how to do this. When I create a descendant class, how do I reference that from my XAML files? They currently have the "navigation:page" tag, so how do I replace that...

When should we choose abstract classes instead of interfaces and when interfaces instead of abstract classes? Is one benefit of using abstract base classes that if external party decides to ext...
Hiya all, I'm hoping to get some tips to kinda help me break out of what i consider after all these years a bad habit of procedural programming. Every time i attempt to do a project in OOP i end up eventually reverting to procedural. I guess i'm not completely convinced with OOP (even though i think i've heard everything good about it...
I'm attempting to create some simple UI components with dojo.gfx. I've managed to extend dojo.gfx.Group, but am out of my depth getting any of the default shapes drawn to the surface. Inspecting the rendered SVG in Firebug, there's rightfully a node but no rect. The simplified class looks like this: dojo.provide("gfxui.SimpleButton")...

Hey--I'm trying to design my first game using the Pygame library for Python, and I was wondering what the best practices are for level design in general. I would love to hear what you guys think are good object oriented design patterns for managing levels. Also, I'm fairly new to Python--thanks! ...
