[Marble-devel] Problem in adding Bookmark in Folder in GeoDataDocument

[gaurav gupta]

Hello Devels,

I am inserting a bookmark in a folder with name folderName which is stored
in GeoDataDocument inside BookmarkManager class(submitted a patch to
reviewboard). Please suggest me how can I do that.

I tried it with the following approach but I realized that it have some
really big bugs. In my approach I used folders() function of
GeoDataContainer which will return a QVector having all the folders. Then I
compared with the name and when it matched append bookmark( which is
GeoDataPlacemark ) in the folder.
wrote following code for that :

void BookmarkManager::addBookmark( const GeoDataPlacemark &bookmark, const
QString &folderName )
{
    QVector<GeoDataFolder> bookmarkFolders = folders();
    QVector<GeoDataFolder>::const_iterator i = bookmarkFolders.constBegin();
    QVector<GeoDataFolder>::const_iterator end = bookmarkFolders.constEnd();

    for (; i != end; ++i ) {
        //Folder found where bookmark should be inserted
        if( !folderName.compare( i->name() ) ){
    //        i->append(bookmark);        uncommenting gives compiler error
            break;
        }
    }
}

QVector<GeoDataFolder> BookmarkManager::folders() const
{
        return d->m_bookmarkDocument->folders();
}

The problem I see is folders() function creates a local copy of QVector and
return that. so adding bookmark to that folder might not work since it is
local copy. So please tell me what should I do and why I am getting compiler
error when I uncomment the line.

The one way I can think of is declare m_vector as a QVector having pointer
to GeoDataFeature ( QVector<GeoDataFeature*> m_vector ) so I can add more
child nodes ( like placemarks in folders ) from outside and the changes can
be reflected in document. Please suggest me and let me know if I'm not clear
with my problem.
