enter

Cmn

Added in 1.3.0

@ExperimentalComposeUiApi
open var enter: (FocusDirection) -> FocusRequester

A custom item to be used when the user requests focus to move focus in (FocusDirection.Enter). An automatic Enter" can be triggered when we move focus to a focus group that is not itself focusable. In this case, users can use the the focus direction that triggered the move in to determine the next item to be focused on.

When you set the enter property, provide a lambda that takes the FocusDirection that triggered the enter as an input, and provides a FocusRequester as an output. You can return a custom destination by providing a FocusRequester attached to that destination, a Cancel to cancel the focus enter or Default to use the default focus enter behavior.

exit

Cmn

Added in 1.3.0

@ExperimentalComposeUiApi
open var exit: (FocusDirection) -> FocusRequester

A custom item to be used when the user requests focus to move out (FocusDirection.Exit). An automatic Exit can be triggered when we move focus outside the edge of a parent. In this case, users can use the focus direction that triggered the move out to determine the next focus destination.

When you set the exit property, provide a lambda that takes the FocusDirection that triggered the exit as an input, and provides a FocusRequester as an output. You can return a custom destination by providing a FocusRequester attached to that destination, a Cancel to cancel the focus exit or Default to use the default focus exit behavior.

focusRect

Added in 1.10.0-rc01

open var focusRect: Rect

Sets the focus area for the associated focus target to which these FocusProperties are applied on.

If you simply ignore and do not set this value, UnsetFocusRect will be used. Or alternatively you can set this value to UnsetFocusRect to prevent other FocusProperties nodes in the chain from customizing the focus area.
