gtk:tree-list-model-passthrough (object)

object -- a gtk:tree-list-model object
passthrough -- true if the model is passing through original row items

The accessor for the passthrough slot of the gtk:tree-list-model class returns whether the g:list-model functions for this object return custom gtk:tree-list-row objects. If false, the g:list-model functions for object return custom gtk:tree-list-row objects. You need to call the gtk:tree-list-row-item function on these objects to get the original item.

If true, the values of the child models are passed through in their original state. You then need to call the gtk:tree-list-model-row function to get the custom gtk:tree-list-row objects.
