The interface that components implement to support the Flex data validation mechanism. The UIComponent class implements this interface. Therefore, any subclass of UIComponent also implements it.
Variables
errorString:String
The text that will be displayed by a component's error tip when a component is monitored by a Validator and validation fails.
You can use the errorString
property to show a
validation error for a component, without actually using
a validator class.
When you write a String value to the errorString
property,
Flex draws a red border around the component to indicate
the validation error, and the String appears in a tooltip
as the validation error message when you move the mouse over
the component, just as if a validator detected a validation error.
To clear the validation error, write an empty String, "",
to the errorString
property.
Note that writing a value to the errorString
property
does not trigger the valid or invalid events; it only changes the
border color and displays the validation error message.
Methods
validationResultHandler(event:ValidationResultEvent):Void
Handles both the valid
and invalid
events
from a validator assigned to this component.
You typically handle the valid
and invalid
events dispatched by a validator by assigning event listeners
to the validators.
If you want to handle validation events directly in the component
that is being validated, you can override this method
to handle the valid
and invalid
events.
From within your implementation, you can use the
dispatchEvent()
method to dispatch the
valid
and invalid
events
in the case where a validator is also listening for them.
Parameters:
event | The event object for the validation. |
