Manages whether the CheckMenuItem is in the 'inconsistent' state.

if this CheckMenuItem is in the inconsistent state, otherwise. If the user has selected a range of elements (such as some text or spreadsheet cells) that are affected by a boolean setting, and the current values in that range are inconsistent, you may want to display the check in an "in between" state. This property turns on "in between" display. Normally you would turn off the inconsistent state again if the user explicitly selects a setting. This has to be done manually, this property only affects visual appearance, it doesn't affect the semantics of the widget. GLib.Property("inconsistent") Property System.Boolean
