## column-width

Arguments: item-list

Returns the width of each column in pixels on `single-item-list` and `multi-item-list` controls. The value `nil` is arbitrarily interpreted as a width of 150 pixels. There is no maximum width.

column-width is a property of the `multi-item-list` and `single-item-list` classes.

### GTK Note

This property is ignored on GTK, where the native `item-list` widget does not support multiple columns.
