AutoFitMode 列挙体

フィールドが DataPresenter の利用可能な領域のサイズに合うように常にサイズ変更されるかどうかを決定する列挙体。変更される場合は、どのフィールドをサイズ変更するかも決定します。

メンバ解説
Alwaysフィールド レイアウトを常に AutoFit モードに設定すると、すべてのフィールドは自動でサイズ変更されます。
DefaultDataPresenterBase.AutoFit が true の場合はデフォルトで ResizeAllFields になり、DataPresenterBase.AutoFit が null の場合は ResizeStarFields、DataPresenterBase.AutoFit が false の場合は None になります。
ExtendLastField最後の論理列のフィールドのみがサイズ変更されます。例えば、垂直方向では、最も右のフィールドのサイズが変更されます。
Neverフィールドは、DataPresenterBase の表示可能領域に基づいて自動的にはサイズ変更されません。
OnlyWithVisibleStarFields明示的な star コンテンツを持つ 1 つの表示可能なフィールドがある場合、フィールド レイアウトで AutoFit モードを有効にします。
