public static bool BeginFoldoutHeaderGroup (Rect position, bool foldout, GUIContent content, GUIStyle style= EditorStyles.foldoutHeader, Action<Rect> menuAction, GUIStyle menuIcon);

パラメーター

foldout 表示されている折り畳みの状態
content 表示するラベル
style オプションの GUIStyle
menuAction The action that happens when you click the icon.
menuIcon Optional GUIStyle for icon.
position Rectangle on the screen to use for the control.

戻り値

bool ユーザーによって選択された折り畳みの状態。 True の場合、サブオブジェクトを表示する必要があります。

説明

それの左側に折り畳み矢印でラベルを作成します。

これは、フォルダのような構造で、親フォルダを展開した場合にのみ子オブジェクトが表示される場合に便利です。このコントロールは、別の BeginFoldoutHeaderGroup に入れ子にすることはできません。これらの折り返しを複数使用するには、各メソッドを EndFoldoutHeaderGroup で終了させる必要があります。


Create a foldable header menu that hides or shows the selected Transform.
