Description
Updates an action to reflect the current state of the TDBMemo.
UpdateAction is called automatically when the application is idle to give the TDBMemo an opportunity to update associated actions. This allows actions to be grayed, checked, or to otherwise reflect the status of the TDBMemo they target.
The Action parameter specifies the action component that should be updated. UpdateAction returns trueif the action component now reflects the state of the component, and false if it did not know how to update the action.
