Sorry, but I have to agree with Alberto - there is actually no way
(that I have found) of listing the currently loaded styles (for a UI
dropdown for example), either with the OGRStyleTable or with the
OGRStyleMgr.
You have to maintain this list yourself.
Plus the OGRStyleTable is not at all private - you actually need one
before you can use the OGRStyleMgr, and the style strings are passed
in and out of both classes quite liberally. An OGRStyleMgr-
>getAllStyles() method would actually be quite useful, although I'm
not sure what it should return (a const char ** ?)

Hi, I'm getting an OGRStyleTable from an OGRDataSource.

Alberto,
Why you need to access private elements of class.
You should not even know they exist.
but I don't find any method to do it sequentially (I
can't read one by one because I don't know their names).
See section 3 for usage example
http://home.gdal.org/projects/opengis/ogr_feature_style_008.html
It explains how to read styles sequentially.
In short I need access to OGRStyleTable::m_papszStyleTable.

I suppose rationale of your concept is bad. You should not neet to
access it.
