#define mainWindow_H#include QWidget
#include QTextEdit
#include QSqlQueryModelclass QSqlTableModel;
class QTableView;enum {Id 0,Eat 1,Taxi 2,Train 3
};class mainWindow : public QWidget
{Q_OBJECTpublic:mainWindow();bool createConnection();void createFakeData();void printMessage(QString message);private:QSqlQueryModel *model;QTableView *view;QTextEdit *textEdit;};#endif 类定义文件mainWindow.cpp: #include QtGui
#include QtSql#include mainWindow.hmainWindow::mainWindow()
{textEditnew QTextEdit();if (!createConnection())return;model new QSqlTableModel(this);model-setQuery(SELECT * FROM [Test$]);model-setHeaderData(Eat, Qt::Horizontal, tr(Eat));model-setHeaderData(Taxi, Qt::Horizontal, tr(Taxi));model-setHeaderData(Train, Qt::Horizontal, tr(Train));view new QTableView;view-setModel(model);view-setSelectionMode(QAbstractItemView::SingleSelection);view-setSelectionBehavior(QAbstractItemView::SelectRows);view-setColumnHidden(Id, false);view-resizeColumnsToContents();view-setEditTriggers(QAbstractItemView::NoEditTriggers);QHeaderView *header view-horizontalHeader();header-setStretchLastSection(true);QVBoxLayout *mainLayout new QVBoxLayout;mainLayout-addWidget(view);mainLayout-addWidget(textEdit);setLayout(mainLayout);setWindowTitle(tr(xlsProcessor));
}bool mainWindow::createConnection()
{QSqlDatabase db QSqlDatabase::addDatabase(QODBC);db.setDatabaseName(Driver{Microsoft Excel Driver (*.xls)};Readonly0;DriverId790;DbqD:\\test.xls;DefaultDirD:\\);if (!db.open()){printMessage(tr(Database Error));return false;}printMessage(tr(Connected Successed!));return true;
}void mainWindow::printMessage(QString message)
{textEdit-append(message);
} 最终效果 转载于:https://www.cnblogs.com/guaipojushi/archive/2012/11/18/2775995.html
