[20:7] extends: object
Allows objects to extend and customize deserialization from ui files. The
GtkBuildable interface includes methods for setting names and properties of
objects, parsing custom tags and constructing child objects. It is
implemented by all widgets and many of the non-widget objects that are
provided by GTK. The main user of this interface is [class@Gtk.Builder].
There should be very little need for applications to call any of these
functions directly. An object only needs to implement this interface if it
needs to extend the GtkBuilder XML format or run any extra routines at
deserialization time.
Buildable (Handle = null)
Creates a new
Buildableby wrapping a native handle or another wrapper.
Handle is the native handle or another wrapper whose handle to adopt.toNativeHandle (Source)
Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from
fn.call(...), another generated wrapper exposinghandle(), or null. Returns null when the argument carries no pointer.
Source is the raw handle, raw buffer, wrapper, or null.A raw pointer carrier or null when no pointer is present.getLib ()
Returns the opened native library for this generated wrapper.
The opened native library.handle ()
Returns the wrapped NativeHandle.
The wrapped NativeHandle.isNull ()
Returns true when the wrapped handle is null.
A bool.describe ()
Returns a small string for debugging generated wrappers.
A string.get_buildable_id ()
Gets the ID of the @buildable object.
GtkBuildersets the name based on the ID attribute of the<object>tag used to construct the @buildable.
