Description
TPageChangeEvent is the type for event handlers that respond when the current page changes in a TTabbedNotebook control.
Sender is the TTabbedNotebook control.
NewTab is the tab that is about to become the selected or current tab.
AllowChange specifies whether the change to a new page is allowed. If the event handler sets AllowChange to false, a new page change doesn't occur.
