this is good: >GMPI must define an in-process customized UI mechanism. Hosts are >not required to support this, but graphical hosts are strongly urged >to do so. this isn't: >Then provided more on XML+layered bitmaps. this needs to be left entirely for the implementation state. if we want to extend the requirements, i'd add: The customized UI mechanism should be capable of being implemented on all target platforms, and if possible should not make any assumptions about the nature of the GUI of the host itself. If a GUI toolkit is used to implement the customized UI mechanism, only cross-platform GUI toolkits or graphics APIs should be considered. you cannot write Halion with XML+layered bitmaps. i want to be able to write GMPI plugins like Halion. --p ---------------------------------------------------------------------- Generalized Music Plugin Interface (GMPI) public discussion list Participation in this list is contingent upon your abiding by the following rules: Please stay on topic.
