解説

MdiTab は、UltraTabbedMdiManager のユーザー インターフェイスを使用して 2 通りの方法で閉じることができます。1 つめは閉じるボタン (MdiTabGroup に「X」として表示される) を使用する方法で、もう 1 つはタブを右クリックしたときに表示されるコンテキスト メニューを使用する方法です。MdiTabGroup に表示される閉じるボタンは MdiTabGroupSettings.ShowCloseButton を False に設定することで非表示にできますが、それでもコンテキスト メニューのオプションは使用可能です。AllowClose が False に解決される場合(デフォルト値は True)、コンテキスト メニューのオプションは表示されず、閉じるボタン(表示されている場合)はタブが選択タブのときに無効になります。AllowClose の設定にかかわらず、MdiTab.Close メソッドを使用してタブを閉じることができます。
