_stopDialogsFromBeingInactivatedDueToIframes

private Object _stopDialogsFromBeingInactivatedDueToIframes()

Since the richTextEditor uses an iframe, it is possible that dialogs containing this component will become inactivated when focus is moved into the iframe. In Firefox 2, we can prevent the inactivation of the dialog by cancelling the blur timeout. In Firefox 3, there is a new activeElement on the document that can be used to avoid this issue. If the dialog is already dismissed and the user clicks inside of the dialog, we really want to make it active. The only way to do that is to abstain from cancelling the timeout since the auto-dismissal manager will then be able to look at the active element and make changes as necessary.

Return:

Object

Handles the events fired by the components that are bound to this component.

Parameters:

event

-
