# convertInteractionPoint(_:toContainerAt:)

Converts an interaction point from display space into the text container’s coordinate system.

## Declaration

```swift
optional func convertInteractionPoint(_ point: CGPoint, toContainerAt containerLocation: any NSTextLocation) -> CGPoint
```

## Parameters

- `point`: The interaction point in display/view-space coordinates.
- `containerLocation`: The location identifying the text container the interaction occurred in.

## Return Value

Return Value The point mapped into the text container’s coordinate system. Return point unchanged when no transform is active.

## Discussion

Discussion NSTextSelectionNavigation calls this method before hit-testing to allow the data source to undo any display transform (rotation, flip, path layout, etc.) applied to the text.
