gui design patterns

Today in Terrylee Cnblog (http://terrylee.cnblogs.com) saw the design patterns related to the whole set of articles, beginners design patterns after reading each article to do some notes and excerpts. What is design mode and what is architecture?

Five common PHP design patterns-the factory model. Five common design patterns in PHP-the factory model has always had a sense of reverence for the design patterns. every time you want to see the

Article Description: visual design of user interface The history of the visual design of the user interface can be described as a process that gradually changes to the real sense. Just as computers have become more and more rapid, designers have added more and more realistic details-such as color, stereo effects, shadows, translucent and even simple physics. Part of these changes have helped impro

This article continues to introduce23 Design Mode SeriesThe Observer pattern. definitionIn the process of software building, the internal structure of collection objects often varies, but for these collection objects, we want to allow external client code to transparently access the elements contained therein while not exposing its internal structure, and this "transparent traversal" also provides the possibility for the same algorithm to operate on a

What is a pattern Before preparing for the final exam, the trouble and the pernicious, really idle to update the article, today and you talk about the design patterns in JavaScript. First, what we need to know is that the pattern is a reusable solution, and the reverse pattern is a bad solution for a problem. JS Anti-pattern Common examples 1. Passing strings to settimeout and setinterval, rather than f

Context.getsystemservice to obtain a system service management object, it first obtains the corresponding Servicefetcher object from the Map collection based on the service name , and then calls The GetService function of the Servicefetcher object obtains the service management object created by the Servicefetcher object. In the getservice function of the Servicefetcher object, first from the list of cache arrays maintained by the context, find if the index of the Servicefetcher object already

Introduction to Template Method Patterns Template method, as the name implies, is the general process of doing some tasks. If there are many self-introduction templates on the Web, the recommendation template, that is, the beginning and end of the content may be similar, and in the middle of the need for customers to modify the use. Design patterns originate from

Design patterns are divided into three main types: creation, structure and behavior. This article describes the observer patterns, template method patterns, command patterns, state patterns, and responsibility chain

I. BACKGROUNDWhen it comes to producer-consumer models, it is necessary to mention multithreading, multithreaded development is commonly used in development, multi-thread programming is more stable than single-threaded,A thread that hangs does not affect the normal operation of the entire program. However, dirty reads occur when multiple threads are manipulating a data source at the same time.Ii. introduction of producer consumer ModelsThe producer-consumer model solves the problem of strong cou

design patterns are divided into three main types: creation, structure and behavior. This article describes the structural pattern.The structure mode includes adapter mode, bridge mode, combination mode, decoration mode, appearance mode, enjoy meta-mode and proxy mode.Adapter Mode: transforms the interface of a class into another interface that the customer wants. The adapter mode makes it possible for thos

2012? What do you think? Past style? " "The end of the world" pronoun? Ha, we all go over, whether you want to and do not want to look forward to, 2013 are safe to come, is not very looking forward to the "rebirth" of 2013, is not want to how to live this special New year, we think of what, reunion? Spring Festival? All things originate? For this "rebirth "The Spring Festival, in addition to dreams and expectations, and some warmth!" I was in the GUI

Design Patterns (3) -- Abstract Factory patterns (Absrtact Factory Pattern), absrtactpattern Definition The essence of the abstract factory mode is to provide interfaces to create a series of related or independent objects without specifying the specific classes of these objects. Understanding In software systems, there are often "a series of mutually dependen

class of system guis, such as Android, add? A set of GUI controls and the android control factory. 3. Reduce client inference. When products in a product family work together, the abstract factory ensures that the client always only uses products in the same product family, instead, you don't need to deduce which product to use based on the current environment. For example, if you use windowsguifacloud, the client does not need to deduce the operatin

The structural design pattern solves the coupling problem between the modules from the structure of the program. The following seven modes are included: Adapter mode: An excuse for the class can be matched to another interface Combination mode: The combination of objects Proxy mode: A Simple object instead of a complex object that will be called later Appearance Mode: A class represents a subsystem Enjoy meta mode: used to

sentence may not be easy-to-understand. To put it bluntly, it means the conventional rule. You only need to clearly describe whether the corresponding occasion is really suitable)5. pattern is a means to record the software architecture. (The meaning of this sentence is to tell you which modes are used in this software architecture, and my colleagues have stipulated that your modifications or extensions must follow the general direction of the mode, the steps against these

together, a D A p T e r mode a D A p T e r is usually used after the system design is complete, and b R i d g e mode You must know beforehand that an abstraction will have more than one implementation part, so is used Therefore, it can be seen from the above description that the use of a bridge or The completed code for the adapter pattern can be viewed as a bridging mode from different viewing angles, or as an adapter mode. 6.

Simple Design Mode Introduction Gof (Gang of Four, which refers to Erich Gamma, Richard Helm, Ralph Johnson John vlissides)'s design patterns (published in 1995) this is the first time that we have elevated the design pattern to a theoretical level and standardized it. This book proposes 23 basic
