Trait glib::object::IsA
[−]
[src]
pub trait IsA<T: StaticType + UnsafeFrom<ObjectRef> + Wrapper>: StaticType + Wrapper + Into<ObjectRef> + UnsafeFrom<ObjectRef> + for<'a> ToGlibPtr<'a, *mut <T as Wrapper>::GlibType> { }
Declares the "is a" relationship.
Self
is said to implement T
.
For instance, since originally GtkWidget
is a subclass of GObject
and
implements the GtkBuildable
interface, gtk::Widget
implements
IsA<glib::Object>
and IsA<gtk::Buildable>
.
The trait can only be implemented if the appropriate ToGlibPtr
implementations exist.
T
always implements IsA<T>
.
