Better than union is to have the single part in one structure and specific bits in their own structure. Depending on how we do the Eet + union support, we may think on how to do it to cover this case as well. I'd say instead of allocate memory and fill it, one could give a "type" value to user callback and then it would receive the correct Eet_Data_Descriptor for that subtype. So union would return the data descriptor with the same struct size for all types, while dynamic would check (switch/case) which one to use, and return the fields properly. This is likely to reduce memory consumption a lot because we often have LOTS of rectangle that have almost no field, while we have very few TEXT/TEXTBLOCK/GRADIENT that consume most memory. BTW, something that could improve memory there is using mempool. -- Gustavo Sverzut Barbieri http://profusion.mobi embedded systems -------------------------------------- MSN: barbi...@gmail.com Skype: gsbarbieri Mobile: +55 (19) 9225-2202 ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
