![]() ![]() Libraryīoth historically, and currently, a library is a collection of code relating to a specific task, or set of closely related tasks which operate at roughly the same level of abstraction. There are various terms relating to collections of related code, which have both historical (pre-1994/5 for the purposes of this answer) and current implications, and the reader should be aware of both, particularly when reading classic texts on computing/programming from the historic era. Generally speaking, this completely explains the differences between the terms. eventually, you've written so many apps that use the same toolkits and libraries that you create a Framework that has a generic version of this boilerplate code already provided so all you need to do is design the look of the UI and handle the events that result from user interaction.So you refactor your work and create a Toolkit that allows you to create your UIs more easily from generic method calls. eventually you find yourself creating the same kind of user interfaces every time you make use of certain libraries.To save yourself time you bundle those functions into Libraries. eventually, after having written a few programs, you find yourself copying functions you already made into new programs.eventually you discover sections of code that you're repeating in your program, so you refactor those into Functions/Methods.Most people miss the fact that these are all nested concepts. However, the explanation could easily be stated more clearly. The answer provided by Barrass is probably the most complete. Unlike library and framework, which are well-defined, I don't think that there is a widely accepted definition of toolkit. What, then, makes a toolkit different from just a bunch of independent libraries? Integration: if you just have a bunch of independent libraries, there is no guarantee that they will work well together, whereas the libraries in a toolkit have been designed to work well together – you just don't have to use all of them.īut that's really just my interpretation of the term. a set of independent libraries that you can pick and choose from. Just the word "kit" seems to suggest some kind of modularity, i.e. ![]() I don't know if the term toolkit is really well defined. NET!)īasically, all the control flow is already in the framework, and there's just a bunch of predefined white spots that you can fill out with your code.Ī library on the other hand is a collection of functionality that you can call. If it doesn't have Inversion of Control, it's not a framework. (This is called the Hollywood Principle: Don't call Us, We'll call You.) This is pretty much the definition of a framework. But with a framework, the control is inverted: the framework calls you. What does this mean? Well, it means that when you call a library, you are in control. ![]() The most important difference, and in fact the defining difference between a library and a framework is Inversion of Control. ![]()
