QTableWidget 导出到表格
跳槽到了新的公司,开始苦逼的出差现场开发,接触到了新的应用。有很多应用需要将Table导出成表格,可以把table导出成csv格式的文件。跟大伙分享一下;
lass TableToExcle : public QDialog { Q_OBJECT public: TableToExcle(QWidget *parent = 0, Qt::WFlags flags = 0); ~TableToExcle(); private: Ui::TableToExcleClass ui; private slots: void addRowSlot(); void delRowSlot(); void exportSlot(); };
TableToExcle::TableToExcle(QWidget *parent, Qt::WFlags flags) : QDialog(parent, flags) { ui.setupUi(this); ui.m_pTable->setColumnCount(4); QTableWidgetItem * item = new QTableWidgetItem("0"); ui.m_pTable->setHorizontalHeaderItem ( 0, item ); item = new QTableWidgetItem("1"); ui.m_pTable->setHorizontalHeaderItem ( 1, item ); item = new QTableWidgetItem("2"); ui.m_pTable->setHorizontalHeaderItem ( 2, item ); item = new QTableWidgetItem("3"); ui.m_pTable->setHorizontalHeaderItem ( 3, item ); ui.m_pTable->setSelectionBehavior(QAbstractItemView::SelectRows); connect(ui.m_pAddBtn,SIGNAL(clicked()),this,SLOT(addRowSlot())); connect(ui.m_pDelBtn,SIGNAL(clicked()),this,SLOT(delRowSlot())); connect(ui.m_pExportBtn,SIGNAL(clicked()),this,SLOT(exportSlot())); } TableToExcle::~TableToExcle() { } void TableToExcle::addRowSlot() { ui.m_pTable->insertRow(ui.m_pTable->rowCount()); } void TableToExcle::delRowSlot() { int index = ui.m_pTable->currentRow (); if (index > -1) { ui.m_pTable->removeRow(index); } } void TableToExcle::exportSlot() { QString fileName = QFileDialog::getSaveFileName(this, tr("Save File")," ",tr("file (*.csv)")); if (!fileName.isEmpty()) { QFile file(fileName); bool ret = file.open( QIODevice::Truncate | QIODevice::WriteOnly); if(!ret) return; QTextStream stream(&file); QString conTents; QHeaderView * header = ui.m_pTable->horizontalHeader() ; if (header) { for ( int i = 0; i < header->count(); i++ ) { QTableWidgetItem *item = ui.m_pTable->horizontalHeaderItem(i); if (!item) { continue; } conTents += item->text() + ","; } conTents += "\n"; } for ( int i = 0 ; i < ui.m_pTable->rowCount(); i++ ) { for ( int j = 0; j < ui.m_pTable->columnCount(); j++ ) { QTableWidgetItem* item = ui.m_pTable->item(i, j); if ( !item ) continue; QString str = item->text(); str.replace(","," "); conTents += str + ","; } conTents += "\n"; } stream << conTents; file.close(); } if( QMessageBox::Yes == QMessageBox::information(0,QObject::tr("文件导出"),QString("文件导出成功,是否打开该文件?"),QMessageBox::Yes,QMessageBox::No) ) { QSettings settings("HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Office",QSettings::NativeFormat); QString szDefault, szPath; bool bSuccess; szPath = settings.value("12.0/Excel/InstallRoot/Path").toString(); if (szPath.isEmpty()) szPath = settings.value("11.0/Excel/InstallRoot/Path").toString(); if (szPath.isEmpty()) szPath = settings.value("10.0/Excel/InstallRoot/Path").toString(); if (szPath.isEmpty()) szPath = settings.value("9.0/Excel/InstallRoot/Path").toString(); if (szPath.isEmpty()) szPath = settings.value("14.0/Excel/InstallRoot/Path").toString(); if (szPath.isEmpty()) { QMessageBox::information(0, "提示", "系统没有安装Office, 不能查看故障报告,请您先安装Microsoft Office."); return; } QProcess * proce = new QProcess; QString szExcelexe = szPath + "excel.exe"; QString szopen = "/safe"; QString szDoc = fileName; QStringList list; list<<szDoc; if( proce ) { proce->start(szExcelexe,list); proce->waitForStarted(5000); //需要等待完成启动 }<pre name="code" class="cpp"> delete proce;
