1. Output HTML format
Restrictions: does not support Word documents in .docx format

}2. Insert Picture QAxObject
Limit: slow
void LHCCreateOfficeAPDF::UseQAxObjectToWord()
{
QString filePN = QFileDialog::getSaveFileName(this, QStringLiteral("Save File"),
QStringLiteral("./未命名"), tr("Word (*.docx *.doc)"));

// 新建文档;

// 以模板 sFile (.dot) 为基础创建文档, sFile为空 表示新建文档;

// 获取当前激活的文档;
QAxObject *m_pWorkDocument = m_pWord->querySubObject("ActiveDocument");

//插入图片;

}
}
// 保存 Word 文档;

m_pWord->dynamicCall("Quit()");
delete m_pWorkDocuments;
delete m_pWord;
OleUninitialize();
}3. Word documents into PDF
void LHCCreateOfficeAPDF::on_pushB_WordToPDF_clicked()
{
// 接口参照网址 https://docs.microsoft.com/zh-CN/office/vba/api/Word.Documents.Open;
// 利用QAxObject实现word转pdf;

QVariant filename(fileName);
QVariant confirmconversions(false);
QVariant readonly(true);
QVariant addtorecentfiles(false);
QVariant passworddocument("");
QVariant passwordtemplate("");
QVariant revert(false);
// querySubObject 用法;
// 参数传得少的时候可以用下面做法，如果多的话就用另外的重载版本，如下;
// QAxObject* querySubObject(const char *name, QList<QVariant> &vars);
// 参数装到一个list里，然后传参就行了
// 打开;
QAxObject* doc = pWordDocuments->querySubObject("Open(const QVariant&, const QVariant&,const QVariant&, "
"const QVariant&, const QVariant&, "

revert);
if (doc)

//转成pdf;

OutputFileName,
ExportFormat,
OpenAfterExport);
//关闭;
doc->dynamicCall("Close(boolean)", false);
}
}Second, generated PPT
CoInitialize (NULL); // create an object com
CoUninitialize (); // Destructor objects com
1. Play PPT
PlayPPT("E:/embedded.pptx");
void LHCCreateOfficeAPDF::PlayPPT(const QString &pptFilePath)

QThread::currentThread()->sleep(3);
slideshowview->dynamicCall("Next()");
}
}

}2. Use template to insert a picture in PPT
QAxObject *pptObject = new QAxObject("PowerPoint.Application", nullptr);
QAxObject *presentationsObj = pptObject->querySubObject("Presentations");

Office::MsoTriState,Office::Single, Office::Single)", params);
}
}
presentationObj->dynamicCall("SaveAs (QString)", filePN.replace("/", "\\"));
pptObject->setProperty("DisplayAlerts", true);
pptObject->dynamicCall("Close(bool)", true);
pptObject->dynamicCall("Quit()");
delete presentationObj;
delete presentationsObj;
delete pptObject; 3. Do not use a template to insert a picture into the PPT
QString filePN = QFileDialog::getSaveFileName(this, QStringLiteral("Save File"),
QStringLiteral(".\\default"), tr("PPT (*.pptx *.ppt)"));
if (filePN.isEmpty()) return;
QAxObject *pptObject = new QAxObject("PowerPoint.Application", nullptr);
//Create a presentation in this project
QAxObject *presentationsObj = pptObject->querySubObject("Presentations");
// 参数 Office::MsoTriState 是否在可视窗口中显示演示文稿; 0:不显示; 1:显示;

if (!presentationObj)
{
return;
}
QVariantList params;
params.append(QVariant("E:\\11.png"));
params.append(-1);
params.append(-1);
params.append(100);
params.append(100);
// Create new Slide
if (QAxObject *slidesbj = presentationObj->querySubObject("Slides"))
{
int sCount = slidesbj->property("Count").toInt();
if (QAxObject *slideMaster = presentationObj->querySubObject("SlideMaster"))
{
if (QAxObject *customLayouts = slideMaster->querySubObject("CustomLayouts"))
{

1, customLayout->asVariant());
int sCount2 = slidesbj->property("Count").toInt();
if (QAxObject *shapesObj = addSlide->querySubObject("Shapes"))
{
// Add picture
shapesObj->querySubObject("AddPicture(QString, Office::MsoTriState, Office::MsoTriState, \
Office::Single, Office::Single)", params);
shapesObj->querySubObject("AddPicture(QString, Office::MsoTriState, Office::MsoTriState, \
Office::Single, Office::Single)", params);
}
}
}
}
}
presentationObj->querySubObject("SaveAs (QString)", filePN.replace("/", "\\"));
pptObject->setProperty("DisplayAlerts", true);
pptObject->dynamicCall("Close(bool)", true);
pptObject->dynamicCall("Quit()");
delete presentationObj;
delete presentationsObj;
delete pptObject;4. PPT to PDF
void MainWindow::openPPT()
{

{
// Open parameter
QAxObject *_powerPointAxObj = new QAxObject("Powerpoint.Application", 0);
if (!_powerPointAxObj) continue;

//FileName Required String. The name of the file to open
//ReadOnly Optional Long. True to open the file with read-only status. If this argument is omitted, the file is opened with read/write status.
//Untitled Optional Long. True to open the file without a title. This is equivalent to creating a copy of the file. If this argument isn't specified, the file name automatically becomes the title of the opened presentation.
//WithWindow Optional Long. True to open the file in a visible window. False to hide the opened presentation. The default value is True.
QAxObject *presentation = presentations->querySubObject("Open(const QString&,int,int,int)",paramList);
if (presentation != nullptr)

presentation->dynamicCall("SaveAs(const QString&,int,int)", paramList);
presentations->dynamicCall("Close()");
delete presentations;
//this->OpenPdf(application_path);
}
}
}
}Third, generate PDF
1. HTML format and output;
void LHCCreateOfficeAPDF::UseHTMLToPdf()
{
QPrinter printer_text;
printer_text.setOutputFormat(QPrinter::PdfFormat);
printer_text.setOutputFileName("E:/HTML.pdf");//pdfname为要保存的pdf文件名;
QTextDocument text_document;
QString html = GetHtmlInfoToFile();//自定义的函数，用来生成html代码;[见 生成Word部分]
text_document.setHtml(html);
text_document.print(&printer_text);
QTextBlock it = text_document.end();
}2. QPainter output;
Restrictions: manual page
Parameter Description:

QPrinter *m_painter(new QPainter);
int m_Width = 0; // insert the picture width;

}
void LHCCreateOfficeAPDF::EndPainterToPdf()
{

}3. Use QPdfWriter output
Restrictions: QT5 version of the above, the manual page
void LHCCreateOfficeAPDF::UseQPdfWriterToPdf()
{

QPainter* pPdfPainter = new QPainter(pPdfWriter); // qt绘制工具

// 标题,22号字
QFont font;
font.setFamily("simhei.ttf");
int fontSize = 22;
font.setPointSize(fontSize);
pPdfPainter->setFont(font); // 为绘制工具设置字体
pPdfPainter->drawText(QRect(0, iTop, iContentWidth, 90), tr("我的标题我骄傲"), option);
// 内容,16号字，左对齐
