protected procedure TTabControl.Change; override; |
Change is an overridden method in TTabControl. It re-implements the method from the ancestor class to signal the OnChange event handler (when assigned) to change the active tab for the control. An internal flag is used to determine if a previous call to OnChange has not been completed. No actions are performed in the method when the flag is set.
Change does not call the inherited method.
