}

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

Associated Constants

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

Provided methods

fn bind_template_callbacks<T>(klass: &mut T) where
    T: WidgetClassSubclassExt, 

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: WidgetClassSubclassExt, 

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.
