# inspectorColumnWidth(min:ideal:max:)

Sets a flexible, preferred width for the inspector in a trailing-column presentation.

## Declaration

```swift
nonisolated func inspectorColumnWidth(min: CGFloat? = nil, ideal: CGFloat, max: CGFloat? = nil) -> some View

```

## Parameters

- `min`: The minimum allowed width for the trailing column inspector
- `ideal`: The initial width of the inspector in the absence of state restoration. ideal influences the resulting width on macOS when a user double-clicks the divider on the leading edge of the inspector. clicks a divider to readjust
- `max`: The maximum allowed width for the trailing column inspector

## Discussion

Discussion Apply this modifier on the content of a inspector(isPresented:content:) to specify a preferred flexible width for the column. Use inspectorColumnWidth(_:) if you need to specify a fixed width. The following example shows an editor interface with an inspector, which when presented as a trailing-column, has a preferred width of 225 points, maximum of 400, and a minimum of 150 at which point it will collapse, if allowed. MyEditorView()     .inspector {         TextTraitsInspectorView()             .inspectorColumnWidth(min: 150, ideal: 225, max: 400)     } Only some platforms enable flexible inspector columns. If you specify a width that the current presentation environment doesn’t support, SwiftUI may use a different width for your column.
