5 QDirModel和QTreeView(QDirModel已被QFileSystemModel代替) model = new QDirModel(this); ui->treeView->setModel(model); // 显示整个文件系统,QDirModel自带有文件系统 QDirModel常用接口:setReadOnly、setSorting // 按文件名进行排序等 QTree
Introduction to Model/View Programming Qt contains a set of item view classes that use a model/view architecture to manage the relationship between data and the way it is presented to the user. The separation of functionality introduced by this architecture gives developers greater flexibility to ...
Advanced Qt Programming / Mark Summerfield, Prentice Hall, ISBN 0-321-63590-6. This book covers Model/View programming on more than 150 pages. The following list provides an overview of example programs contained in the first three books listed above. Some of them make very good templates for...
这其中的类关系如下图所示(出自 C++ GUI Programming with Qt 4, 2nd Edition) 使用Qt 的 model-view 架构,我们可以让 model 是取回 view 所要展示的数据,这样就可以在不降低性能的情形下处理大量数据。并且你可以把一个 model 注册给多个 view,让这些 view 能够显示同样的数据,也就是为同一个数据提供不同的...
本文翻译自QT官方文档QT 4.8 Model/View Programming 一、Model/View框架简介 Qt4推出了一组新的项视图类,使用Model/View框架来管理数据与表示层的关系。Model/View框架带来的功能上的分离给了开发人员更大的弹性来定制数据项的表示,并且提供一个标准的model接口,使得更多的数据源可以被项视图类使用。本文简要介绍了Mo...
Model/View Programmingdoc.qt.io/qt-5.15/model-view-programming.html 简介 源数据由模型 (Model) 读取,然后在视图 (View) 组件上显示和编辑,在界面上编辑修改的数据又通过模型保存到源数据。 Model/View 结构将数据模型和用户界面分离开来,分别用不同的实现,是一种显示和编辑数据的有效结构,在处理大型数据...
This may seem complicated at first, but once you take a closer look, it is not only easy to grasp, but the many benefits of model/view programming also become clearer. In the process, we will learn about some basic technologies provided by Qt, such as: The difference between standard ...
intmain(intargc,char*argv[]){QApplicationapp(argc,argv);// 创建一个Qt应用程序对象,它管理GUI事件循环和设置QSplitter*splitter=newQSplitter;// 创建一个QSplitter(窗口部件),它是一个容器,可以用来在窗口中创建多个视图。QFileSystemModel*model=newQFileSystemModel;// 创建一个QFileSystemModel对象,这是一个文件...
Qt学习之路(38): model-view架构 简介: 从这一节开始,我们进入model-view阶段。这一阶段主要还是依据 C++ GUI Programming with Qt4, 2nd Edition。 我们的系统有很多数据显示的需求,比如从数据库中把数据取出,然后以自己的方式显示在我们自己的应用程序的界面中。进行这一操作的典型方式是使用Qt的Item View类。
