void wxScopeGuard::Dismiss

(

)

Call this method to dismiss the execution of the action on scope exit.

A typical example:

            Update1();

            // ensure that changes done so far are rolled back if the next
            // operation throws
            wxScopeGuard guard = wxMakeGuard(RollBack);
            Update2();

            // it didn't throw so commit the changes, i.e. avoid rolling back
            guard.Dismiss();
