# Maximum Open Projects Sample [][docs]
|
|
*Reference: [Plugin Services in IntelliJ SDK Docs][docs:plugin_services]*
|
|
|
|
## Quickstart
|
|
|
|
Maximum Open Projects Sample implements a `StartupActivity` extension point to run on project open as well as a
|
|
`ProjectManagerListener` for tracking projects being closed.
|
|
Both use `ProjectCountingService` application-level [light service][docs:plugin_services:light_services].
|
|
It provides methods to increase and decrease the counter of currently opened projects in the IDE.
|
|
When opening more projects than the maximum allowed (3), a message dialog is shown.
