gtk:builder-add-objects-from-file (builder path &rest args)

builder -- a gtk:builder object
path -- a pathname or namestring with the name of the file to parse
args -- strings with the object IDs to build

The positive value on success, 0 if an error occurred.

Parses a file containing a gtk:builder UI definition building only the requested objects and merges them with the current contents of builder. Upon errors 0 will be returned. If you are adding an object that depends on an object that is not its child, for instance a gtk:tree-view widget that depends on its gtk:tree-model implementation, you have to explicitely list all of them in args.
