Required methods

fn get_object<T: IsA<Object>>(&self, name: &str) -> Option<T>

Gets the object named name. Note that this function does not increment the reference count of the returned object.

name

name of object to get

Returns

the object named name or None if it could not be found in the object tree.

fn add_from_file<T: AsRef<Path>>(&self, file_path: T) -> Result<(), Error>

Parses a file containing a [Builder UI definition][BUILDER-UI] and merges it with the current contents of self.

Most users will probably want to use Builder::new_from_file.

If an error occurs, 0 will be returned and error will be assigned a glib::Error from the GTK_BUILDER_ERROR, G_MARKUP_ERROR or G_FILE_ERROR domain.

It’s not really reasonable to attempt to handle failures of this call. You should not use this function with untrusted files (ie: files that are not part of your application). Broken Builder files can easily crash your program, and it’s possible that memory was leaked leading up to the reported failure. The only reasonable thing to do when an error is detected is to call g_error.

filename

the name of the file to parse

Returns

A positive value on success, 0 if an error occurred
