QT Model/View

Qt中的View主要有三种QListView,QTreeView,QTableView

而对应的Model是:QStringListmodel,QAbstractItemmodel,QStandardItemModel

基本原理就是构造出View,和Model然后通过View的setmodel方法,将两者结合起来

QListView/QStringListModel

#include <qapplication>#include <qabstractitemmodel>#include <qstringlistmodel>#include <qstringlist>#include <qlistview>int main(int argc, char *argv[]){    QApplication a(argc, argv);    QStringList numbers;    numbers<<"caterpillar"<<"momor"<<"bush"<<"bee";    QAbstractItemModel *model=new QStringListModel(numbers);    QListView *view=new QListView;    view->setWindowTitle("QListView&Model");    view->setModel(model);    view->show();    return a.exec();}

运行结果:

QTableView/QStandardItemModel

#include <qapplication>#include <qstandarditemmodel>#include <qstandarditem>#include <qtableview>int main(int argc, char *argv[]){ QApplication a(argc, argv); QStandardItemModel *model=new QStandardItemModel; model->setItem(0,0,new QStandardItem("January")); model->setItem(1,0,new QStandardItem("February")); model->setItem(0,1,new QStandardItem("10,000")); model->setItem(1,1,new QStandardItem("20,000")); QTableView *view1=new QTableView; view1->setModel(model); QTableView *view2=new QTableView; view2->setModel(model); view1->show(); view2->show(); return a.exec();}

运行结果:
