Extending napari

There are a number of ways to extend your usage of the napari application:

• Adding widgets: adding a widget (new GUI interaction element) to your napari application

• Connecting callbacks: customize the behavior of napari by connecting an action (function) to an event via the event loop:

  • Key press: perform an action based on a keyboard shortcut

  • Mouse event: perform an action based on a mouse event

  • Layer/viewer event: perform an action when a layer or napari viewer state changes

None of the above require you to create a plugin but you can turn your napari ‘extension’ into a plugin, which could be shared with the community.
