gtk:tree-view-column-spacing (object)

object -- a gtk:tree-view-column object
spacing -- an integer for the distance between cell renderers in pixels

The accessor for the spacing slot gets or sets the spacing of the tree view column, which is the number of pixels to place between cell renderers packed into it. The gtk:tree-view-column implementation is deprecated since 4.10. Please do not use it in newly written code.
