FocusManager

tessera_ui::focus

Struct FocusManager 

Source 
pub struct FocusManager;
Expand description

Owner-scoped focus manager for traversal and forced clear operations.

Use the focus manager to trigger application-level traversal without storing a specific scope or requester.

§Examples

use tessera_ui::FocusManager;

let _manager = FocusManager::current();
