## Member Function Documentation

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();
