WindowGainedFocus

floem_test::prelude::el

Struct WindowGainedFocus 

Source 
pub struct WindowGainedFocus;
Expand description

Receives Event::Window FocusGained variant — fired when the window gains OS-level input focus (distinct from view-level focus tracked by FocusGained).

§Routing

Dispatched to Target phase only on all views that have registered this listener.

§Default Actions

No preventable default action.
