C Qt设计模式(第2版)是美国萨福克大学已使用十余年的经典教程，利用跨平台开源软件开发框架Qt阐释了C 和设计模式中的主要思想。全书共分四个部分：第一部分介绍C 、UML、Qt、模型-视图、SQL、XML、设计模式等基础知识，目的是为零基础的C 初学者铺垫一条学习面向对象编程的快捷之路；第二部分讲解内存访问、继承等重要的C 特性，是前一部分的延伸和拓展；第三部分使用Phonon编写了一个多媒体播放器，展示了主要技术理念的应用方法；附录部分给出了C 保留关键字、Debian和Qt程序开发环境的配置等内容。每节的练习题和各章后面的复习题，既可作为课堂上的讨论题，也可进一步启发读者对于关键知识点的思考。【核心代码】C   Qt设计模式  第2版(中文版).pdfQT设计模式Introduction to Design Patterns in C with Qt 2nd Edition.pdfansicastarithmeticarraysbashbookpagecarclasscardgamecastscircularclargsclassesclipboardcommon.pricomplexcompositeconstconstptrcontainerscontinuectorctorpolydebuggingderivationdesignerdestructordockearly-examplesellipsisencapsulationenumsenvironmenteventloopexceptionsfindchildrenfunctionsfunctorsgenericgotohandoutshugeintiostreamiterationjobseekerlayoutslibslifecycleloginlogtailmetatypemodelviewmultinheritancemystringnamespacenewfailureoperatorspointer-containerpointerspolymorphic1.ccpolymorphic2.ccpreprocessorprivatederivpropertiespuzzleqappqobjectqonsoleqstdqstringqtioqtrttiqtstreamsquizzesreferencereflectionregex-testerregexprttiserializersqlstaticsstdstreamsstlstoragestructdemosubobjectswitchtemplatesthreadstimertypesundo-demovalidatewidgetsxml
