[webkit-dev] Reading from Object

[Soheil Servati Beiragh]

I think my issue some kind of lack of knowledge in C++. I'm trying to redesign the the text placement engine in webkit. For my purpose I need to get access to font face which is stored in the place I mentioned. I know that they are private but I want to read them, and I know it is possible to do so.

What are you trying to do here? Clearly, all member variables are private here so you shouldn't be accessing directly by "m_fontlist.m_ptr->m_cachePrimarySimpleFontData->m_platformData.m_face".

I don't know much about the rendering engine but perhaps other contributors can help you out if you give us more context in which you're trying to do this.
