Import style from external document

Question

Is there a helper class to import styles similar to load text styles (without the gui) in paragraph styles flyout menu, or does the work have to be done manually creating style if it doesn't exist and editing if it does etc..
Any pointers appreciated

Answer 1

Here is a snippet of code I use to merge styles from a master document to another document.
Entry: IDatabase* docdb (database for dest doc)
    ISysFileData* sourceFileData (file information for src doc)
do
    InterfacePtr<IDocument> docp((IDocument*)docdb->Instantiate(docdb->GetRootUID(), IDocument::kDefaultIID));
    //    Load the character and paragraph styles
    InterfacePtr<ICommand> charParaCmd(CmdUtils::CreateCommand(kLoadStyleCmdBoss));
    if (charParaCmd == NULL) break;
    InterfacePtr<IBoolData> cpOverrideLocalStyles(charParaCmd, UseDefaultIID());
    if (cpOverrideLocalStyles == NULL) break;
    cpOverrideLocalStyles->Set(true);
    InterfacePtr<ISysFileData> cpSysFile(charParaCmd, IID_ISYSFILEDATA);
    if (cpSysFile == NULL) break;
    cpSysFile->Set(sourceFileData->GetSysFile());
    InterfacePtr<IIntData> cpLoadOptions(charParaCmd, IID_IINTDATA);
    if (cpLoadOptions == NULL) break;
    cpLoadOptions->Set(ILoadStyleCmdData::kLoadParaCharStyles);
    InterfacePtr<ISelectivelyLoadStyleCmdData> cpLoadStyleCmdInfo(charParaCmd, IID_ISELECTIVELYLOADSTYLECMDDATA);
    if (cpLoadStyleCmdInfo == NULL) break;
    cpLoadStyleCmdInfo->SetGlobalClashResolutionStrategy(StyleClashResolutionTypes::kLoadAllW ithOverwrite);
    UIDList itemList(docp->GetDocWorkSpace());
    charParaCmd->SetItemList(itemList);
    status = CmdUtils::ProcessCommand(charParaCmd);
} while (false);
Hope it helps.
