# cascadeTopLeft(from:)

Positions the window’s top-left to a given point.

## Declaration

```swift
func cascadeTopLeft(from topLeftPoint: NSPoint) -> NSPoint
```

## Parameters

- `topLeftPoint`: The new top-left point, in screen coordinates, for the window. When doc://com.apple.documentation/documentation/Foundation/NSZeroPoint, the window is not moved, except as needed to constrain to the visible screen

## Return Value

Return Value The point shifted from top left of the window in screen coordinates.

## Discussion

Discussion The returned point can be passed to a subsequent invocation of cascadeTopLeft(from:) to position the next window so the title bars of both windows are fully visible.
