Interface IValidatableElement<TValueType>

Interface used on UI elements which handle value validation. Value validation implies the UI element has a value property, hence this interface inherits from UnityEngine.UIElements.INotifyValueChanged<T>.

Type Parameters

TValueType	The type of the value.

validateValue

Set this property to a reference of your custom function which will validate the current value of a UI element. This function will be invoked automatically by the UI element implementation in order to update the invalid state property.

If the property is null, there wont be any validation process so by convention the value will be always valid.

Declaration

Func<TValueType, bool> validateValue { get; set; }
