Package ui provides all public UI elements intended to be repurposed in other applications. Specifically, a single
|
|
Handler object is provided to allow consuming applications (such as grype) to check if there are UI elements the handler
|
|
can respond to (given a specific event type) and handle the event in context of the given screen frame object.
