canDelete

True if this element can be deleted interactively, false otherwise. The value of InteractionConfiguration.allowDeletingSelectedElement of the current GeometryEditor.tool determines this value. The element can be deleted programmatically regardless of this value, for example using GeometryEditor.deleteSelectedElement().

A GeometryEditorMidVertex is not part of the GeometryEditor.geometry state, and therefore can never be deleted from the geometry regardless of the InteractionConfiguration settings.
