# RegionOfInterestChannels

### Purpose
This module defines a Prism event for publishing and subscribing to region of interest (ROI) channel selection changes. It enables loosely-coupled communication between components when users select channels associated with a specific region of interest, carrying both channel identifiers and names along with context about the consumer.

### Public Interface

- Inherits from `PubSubEvent<RegionOfInterestChannelsSelectedEventArgs>`
- A Prism event type used for pub/sub messaging across the application

**`RegionOfInterestChannelsSelectedEventArgs`**
- Constructor: `RegionOfInterestChannelsSelectedEventArgs(string roiSuffix, string[] selectedChannelNames, long[] selectedChannelIds, object o)`
- Properties (all read-only):
  - `string RegionOfInterestSuffix` - Suffix identifier for the region of interest
  - `string[] ChannelNames` - Array of selected channel names
  - `long[] ChannelIds` - Array of selected channel IDs
  - `object Consumer` - Reference to the object consuming this selection
