C++ wrapper

For the integration of ONLYOFFICE Document Builder into any application, the C++ doctrenderer library is used. The current application version contains six main classes:

• CDoctrenderer class - used by ONLYOFFICE Document Builder in the file conversion process.
• CString class - the string class with the wchar_t* property.
• CDocBuilder class - used by ONLYOFFICE Document Builder for the document file (text document, spreadsheet, presentation, form document, PDF) to be generated.
• CDocBuilderContext class - used by ONLYOFFICE Document Builder for getting JS context for working.
• CDocBuilderContextScope class - the stack-allocated class which sets the execution context for all operations executed within a local scope.
• CDocBuilderValue class - used by ONLYOFFICE Document Builder for getting the results of called JS commands. It represents a wrapper for a JS object.

Example

C++

#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(OFFICESTUDIO_FILE_DOCUMENT_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(OFFICESTUDIO_FILE_DOCUMENT_DOCX, sDstPath.c_str());
    oBuilder.CloseFile();

    CDocBuilder::Dispose();

    return 0;
}

.docbuilder
