A handle represents a primitive area that can request, receive and lose the focus. A visible UI is made of many handles, of which at most one can be active.

Create a new handle

Request the focus

Release the focus (if the handle has it)

status represents the state in which a handle can be. Externally we care about having or not the focus, which can be queried with the has_focus function. Internally, status also keeps track of conflicts (if multiple handles requested the focus).

A status that has no focus and no conflicts

Get the status of a focus handle. The status is a reactive value: it will evolve over time, as focus is received or lost.

Check if this status corresponds to an active focus
