Function

Common

fun DelegatableNode.requestFocusForChildInRootBounds(
    left: Int,
    top: Int,
    right: Int,
    bottom: Int,
): Boolean

Attempts to request focus for the most suitable focusable child node that overlaps with the given rect area (left, top, right, bottom).

The rectangle is interpreted in the coordinate space relative to the compose root. See androidx.compose.ui.layout.LayoutCoordinates.localToRoot for converting local coordinates to the root coordinates.

Parameters


left	is the left edge of the rectangle, in pixels relative to the compose root.
top	is the top edge of the rectangle, in pixels relative to the compose root.
right	is the right edge of the rectangle, in pixels relative to the compose root.
bottom	is the bottom edge of the rectangle, in pixels relative to the compose root.

Returns


	`true` if a matching child was found and focus was granted; `false` if no such child exists, it is already focused, or the focus request failed.
