Maximum Open Projects Sample

Reference: Plugin Services in IntelliJ SDK Docs

Quickstart

Maximum Open Projects Sample implements a ProjectManagerListener with two methods applied to check if the current projects have been opened or closed. Each method refers to the ProjectCountingService service registered as an applicationService extension point. It provides methods to increase and decrease the global counter of the currently opened projects in the IDE. After opening each one, a message dialog is presented to the user with the current number.
