Hi,
I'm new to Mac programming (and software engineering in general), so I apologize in advance if my terminology is wrong. I'm currently developing a plug-in (a Print Dialog Extension to be exact) and wanted to make sure only one instance of the plug-in is allowed to be in "editing mode" for information that will be saved on a preference file. Since the plug-in can be loaded by different applications, I'm assuming using distributed objects makes the most sense to allow the plug-in instances to be aware of each other (on a single system). For my implementation, I was going to vend a helper tool that's responsible for saving information on the preference file. Ideally, I want only one instance of the helper tool to exist and have it shared across multiple plug-ins. The helper tool should only be destroyed if there are no plug-ins loaded on the machine. I was planning to have the helper tool also maintain the exclusive "editing mode" among the instances. To achieve this structure, I need a way for the helper tool to hang around until all instances of the plug-in are destroyed. Any suggestions will be greatly appreciated.
