# inspectorColumnWidth(_:)

Sets a fixed, preferred width for the inspector containing this view when presented as a trailing column.

## Declaration

```swift
nonisolated func inspectorColumnWidth(_ width: CGFloat) -> some View

```

## Parameters

- `width`: The preferred fixed width for the inspector if presented as a trailing column.

## Discussion

Discussion Apply this modifier on the content of a inspector(isPresented:content:) to specify a fixed preferred width for the trailing column. Use inspectorColumnWidth(min:ideal:max:) if you need to specify a flexible width. The following example shows an editor interface with an inspector, which when presented as a trailing-column, has a fixed width of 225 points. The example also uses interactiveDismissDisabled(_:) to prevent the inspector from being collapsed by user action like dragging a divider. MyEditorView()     .inspector {         TextTraitsInspectorView()             .inspectorColumnWidth(225)             .interactiveDismissDisabled()     } note: A fixed width does not prevent the user collapsing the inspector on macOS. See interactiveDismissDisabled(_:).
