Remarks
Value validation implies the UI element has a value property,
hence this interface inherits from UnityEngine.UIElements.INotifyValueChanged`1.
Properties

True if the current value set on the UI element is invalid, False otherwise.
Declaration
bool invalid { get; set; }Property Value
| Type | Description |
|---|---|
| bool |
Remarks
The invalid state is handled by the returned result of the validateValue function.
validateValue
Set this property to a reference of your custom function which will validate the current value of a UI element.
Declaration
Func<TValue, bool> validateValue { get; set; }Property Value
| Type | Description |
|---|---|
| Func<TValue, bool> |
Remarks
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.
