FocusRestorationTarget

tessera_ui::focus

Struct FocusRestorationTarget 

Source 
pub struct FocusRestorationTarget { /* private fields */ }
Expand description

A saved focus target that can be restored while it remains available.

Use FocusManager::save_focus before showing temporary interactive content. Restoration does not wait for a removed or disabled target to become available.

Implementations§

Source§

impl FocusRestorationTarget

Source

pub fn restore(self) -> bool

Restores focus if the target is attached, enabled and available.

Returns false when the window is unfocused or another target has captured focus. Check availability after layout when target properties have changed.
