Hi Mathias , Thanks a lot for your reply . Few comments from my side . [Mathias] I don't understand how the port relates to the viewing functionality. I > would expect that changes in the vcl pluging layer won't affect any code > in framework, sw, sc etc. [Monali] : To start with the porting to directfb , i intend to used the sw,sc only to viewing Microsoft docs and xls . Basically want to open the documents in read only mode with these packages and get this working with the GTK-DirectfB plugin that i intend to add in OOo
When porting these OOo applications ( like writer, calc, impress ) to directfb plugin, I want to understand how the writer , calc and impress module interact with VCL. Do all the three have the same way of interaction with VCL layer.What layers do i need to understand to get the path from application modules to the VCL layer ? What is the role played at modules in frramework layer. Is there any documentation ? Any pointers from you will really help. Is there any way, to get a list of modules that the swriter/calc/impress depend on . Is there any way that i kind of find only the relevant modules in the large OOo code that i would need to build/test. Also is it possible for me to disable other modules not required for viewing functionality as dtrans ( clipboard functionality) and which make X calls .
