C++

For the integration of ONLYOFFICE Document Builder into any application, the C++ doctrenderer library is used.

Classes​

The current application version contains four main classes:

NameDescription
CDocBuilderUsed by ONLYOFFICE Document Builder for the document file (text document, spreadsheet, presentation, form document, PDF) to be generated.
CDocBuilderContextUsed by ONLYOFFICE Document Builder for getting JS context for working.
CDocBuilderContextScopeThe stack-allocated class which sets the execution context for all operations executed within a local scope.
CDocBuilderValueUsed by ONLYOFFICE Document Builder for getting the results of called JS commands. It represents a wrapper for a JS object.

Example​

#include "./../common_deploy.h"
#include "../docbuilder.h"
#include "./utils.cpp"

using namespace NSDoctRenderer;
int main(int argc, char *argv[])
{
    std::wstring sProcessDirectory = NSUtils::GetProcessDirectory();
    std::wstring sWorkDirectory = NSUtils::GetBuilderDirectory();

    CDocBuilder::Initialize(sWorkDirectory.c_str());

    CDocBuilder oBuilder;
    oBuilder.SetProperty("--work-directory", sWorkDirectory.c_str());

    oBuilder.CreateFile("docx");

    CContext oContext = oBuilder.GetContext();
    CContextScope oScope = oContext.CreateScope();

    CValue oGlobal = oContext.GetGlobal();

    CValue oApi = oGlobal["Api"];
    CValue oDocument = oApi.Call("GetDocument");
    CValue oParagraph = oApi.Call("CreateParagraph");
    oParagraph.Call("SetSpacingAfter", 1000, false);
    oParagraph.Call("AddText", "Hello, world!");
    CValue oContent = oContext.CreateArray(1);
    oContent[0] = oParagraph;
    oDocument.Call("InsertContent", oContent);

    std::wstring sDstPath = sProcessDirectory + L"/result.docx";
    oBuilder.SaveFile("docx", sDstPath.c_str());
    oBuilder.CloseFile();

    CDocBuilder::Dispose();

    return 0;
