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 of the gtk:tree-view-column class 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.
