Aspose::Words::Revision::get_ParentStyle method

Revision::get_ParentStyle method

Gets the immediate parent style (owner) of this revision. This property will work for only for the StyleDefinitionChange revision type.

System::SharedPtr<Aspose::Words::Style> Aspose::Words::Revision::get_ParentStyle()

Examples

Shows how to work with a document’s collection of revisions.

// This collection itself has a collection of revision groups.
// Each group is a sequence of adjacent revisions.
std::cout << revisions->get_Groups()->get_Count() << " revision groups:" << std::endl;

// Iterate over the collection of groups and print the text that the revision concerns.
{
    SharedPtr<System::Collections::Generic::IEnumerator<SharedPtr<RevisionGroup>>> e = revisions->get_Groups()->GetEnumerator();
    while (e->MoveNext())
    {
        std::cout << (String::Format(u"\tGroup type \"{0}\", ", e->get_Current()->get_RevisionType()) +
                      String::Format(u"author: {0}, contents: [{1}]", e->get_Current()->get_Author(), e->get_Current()->get_Text().Trim()))
                  << std::endl;
    }
}

// Each Run that a revision affects gets a corresponding Revision object.
// The revisions' collection is considerably larger than the condensed form we printed above,
// depending on how many Runs we have segmented the document into during Microsoft Word editing.
std::cout << "\n" << revisions->get_Count() << " revisions:" << std::endl;

    while (e->MoveNext())
    {
        // A StyleDefinitionChange strictly affects styles and not document nodes. This means the "ParentStyle"
        // property will always be in use, while the ParentNode will always be null.
        // Since all other changes affect nodes, ParentNode will conversely be in use, and ParentStyle will be null.
