gtk:builder-add-from-string (builder string)

builder -- a gtk:builder object
string -- a string to parse

True on sucess, false if an error occured.

Parses a string containing a gtk:builder UI definition and merges it with the current contents of the builder. This function is useful if you need to call the gtk:builder-current-object function to add user data to callbacks before loading the gtk:builder UI definition. Otherwise, you probably want the gtk:builder-new-from-string function instead.

If there is an error parsing the string then the program will be aborted.
