A trait for setting up template callbacks inside class_init. This trait is implemented automatically by the template_callbacks macro.

Required Associated Constants

const CALLBACKS: &'static [(&'static str, fn(_: &[Value]) -> Option<Value>)]

Provided Methods

fn bind_template_callbacks<T>(klass: &mut T)

where T: WidgetClassExt,

Binds the template callbacks from this type into the default template scope for klass.

fn bind_template_callbacks_prefixed<T>(klass: &mut T, prefix: &str)

where T: WidgetClassExt,

Binds the template callbacks from this type into the default template scope for klass, prepending prefix to each callback name.

fn add_callbacks_to_scope(scope: &BuilderRustScope)

Binds the template callbacks from this type into scope.

fn add_callbacks_to_scope_prefixed(scope: &BuilderRustScope, prefix: &str)

Binds the template callbacks from this type into scope, prepending prefix to each callback name.
