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 [TemplateCallback]

Provided Methods

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

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

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

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
