gtk-tree-view-level-indentation (object)

object -- a gtk-tree-view widget
indentation -- an integer with the amount, in pixels, of extra indentation

Accessor of the level-indentation slot of the gtk-tree-view class.

The slot access function gtk-tree-view-level-indentation returns the amount, in pixels, of extra indentation for child levels in the tree view in addition to the default indentation. The slot access function (setf gtk-tree-view-level-indentation) sets the amount of extra indentation.

The value should be specified in pixels, a value of 0 disables this feature and in this case only the default indentation will be used. This does not have any visible effects for lists.
