addObjectsFromFile
open fun addObjectsFromFile(filename: String, objectIds: List<String>): <Error class: unknown class><Boolean>
Parses a file containing a UI definition building only the requested objects and merges them with the current contents of @builder.
Upon errors, 0 will be returned and @error will be assigned a GError from the %GTK_BUILDER_ERROR, %G_MARKUP_ERROR or %G_FILE_ERROR domain.
If you are adding an object that depends on an object that is not its child (for instance a GtkTreeView that depends on its GtkTreeModel), you have to explicitly list all of them in @object_ids.
Return
true on success, false if an error occurred
Parameters
filename
the name of the file to parse
objectIds
nul-terminated array of objects to build
