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

builder -- a gtk:builder object
string -- a string to parse
args -- strings with the object IDs to build

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

Parses a string containing a gtk:builder UI definition building only the requested objects and merges them with the current contents of builder. 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.
