}Required Methods
Parses a resource file containing a [GtkBuilder UI definition][BUILDER-UI]
and merges it with the current contents of self.
Most users will probably want to use Builder::from_resource().
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_RESOURCE_ERROR
domain.
It’s not really reasonable to attempt to handle failures of this
call. The only reasonable thing to do when an error is detected is
to call g_error().
resource_path
the path of the resource file to parse
Returns
A positive value on success, 0 if an error occurred
Parses a string containing a [GtkBuilder UI definition][BUILDER-UI]
and merges it with the current contents of self.
Most users will probably want to use Builder::from_string().
Upon errors 0 will be returned and error will be assigned a
glib::Error from the GTK_BUILDER_ERROR, G_MARKUP_ERROR or
G_VARIANT_PARSE_ERROR domain.
It’s not really reasonable to attempt to handle failures of this
call. The only reasonable thing to do when an error is detected is
to call g_error().
buffer
the string to parse
length
the length of buffer (may be -1 if buffer is nul-terminated)
Returns
A positive value on success, 0 if an error occurred
Parses a resource file containing a [GtkBuilder UI definition][BUILDER-UI]
building only the requested objects and merges
them with the current contents of self.
Upon errors 0 will be returned and error will be assigned a
glib::Error from the GTK_BUILDER_ERROR, G_MARKUP_ERROR or G_RESOURCE_ERROR
domain.
If you are adding an object that depends on an object that is not
its child (for instance a TreeView that depends on its
TreeModel), you have to explicitly list all of them in object_ids.
resource_path
the path of the resource file to parse
object_ids
nul-terminated array of objects to build
Returns
A positive value on success, 0 if an error occurred

fn connect_signals<P: FnMut(&Builder, &str) -> Box<dyn Fn(&[Value]) -> Option<Value> + 'static>>(
&self,
func: P
)
Main private entry point for building composite container components from template XML.
This is exported purely to let gtk-builder-tool validate templates, applications have no need to call this function.
widget
the widget that is being extended
template_type
the type that the template is for
buffer
the string to parse
length
the length of buffer (may be -1 if buffer is nul-terminated)
Returns
A positive value on success, 0 if an error occurred
