示例1: QWidget

: QWidget(parent)
{
resize(400,300);
if(connect())
{
QTableView *view = new QTableView(this);
QSqlRelationalTableModel *model = new QSqlRelationalTableModel;//要先有数据才能创建model,也就是先连接数据库局
view->setGeometry(0,0,400,300);
view->setModel(model);
model->setTable("student");
model->setSort(0,Qt::AscendingOrder);
// model->setHeaderData(0,Qt::Horizontal,"Name");//from 0
// model->setHeaderData(1,Qt::Horizontal,"Age");
// model->setHeaderData(2,Qt::Horizontal,"likes");
model->setRelation(3,QSqlRelation("city","id","name"));
model->select();
// view->setModel(model);
view->setSelectionMode(QAbstractItemView::SingleSelection);//设置选择模式
view->setSelectionBehavior(QAbstractItemView::SelectRows);//选择行
// view->resizeColumnsToContents();//tiaozhengziti
view->setEditTriggers(QAbstractItemView::DoubleClicked);//不可编辑?
QHeaderView *header = view->horizontalHeader();
header->setStretchLastSection(true);
view->setItemDelegate(new QSqlRelationalDelegate(view));
// QHeaderView *head = view->verticalHeader();
// head->setStretchLastSection(true);
// view->show();
// this?->show();
}
