Windows の要件

例

ここでは、XYFocusTransferringFromPrimaryView イベントを処理し、アプリケーションでフォーカスを受け取る UI 要素を特定する方法を示します。 フォーカス候補は、最後の入力ウィンドウの子要素の境界 rect に対する相対位置に基づいて区別されます。

private void OnXYFocusTransferringFromPrimaryView(CoreInputView sender,
CoreInputViewTransferringXYFocusEventArgs args)
{
    bool acceptXYFocusTransfer = false;

    switch (args.Direction)
    {
        case CoreInputViewXYFocusTransferDirection.Down:
            // If focus navigation is moving down,
            // set focus to the top element (usernameTextBox).
            this.usernameTextBox.Focus(FocusState.Programmatic);
            acceptXYFocusTransfer = true;
            break;

        case CoreInputViewXYFocusTransferDirection.Up:
            // If focus navigation is moving up,
            // there are two focus candidates.
            // Check the Origin rect to determine the more
            // suitable candidate.
            if ((args.Origin.X + (args.Origin.Width / 2.0)) <
            Window.Current.Bounds.Width / 2.0)
            {
            this.cancelButton.Focus(FocusState.Programmatic);
            }
            else
            {
            this.submitButton.Focus(FocusState.Programmatic);
            }
            acceptXYFocusTransfer = true;
            break;

        case CoreInputViewXYFocusTransferDirection.Left:
        case CoreInputViewXYFocusTransferDirection.Right:
            // If focus navigation is moving left or right,
            // maintain focus on the currently focused UI element.
            acceptXYFocusTransfer = true;
            break;

        default:
            // Don't accept XY focus movement.
            break;
    }

    if (acceptXYFocusTransfer)
    {
        args.TransferHandled = true;
        this.KeyDown += OnMainPageKeyDown;
    }
}

注釈

プライマリ ビューは CoreInputViewKind.Keyboard ビューまたは CoreInputViewKind.Handwriting ビューのいずれかを参照しますが、CoreInputView には CoreInputViewKind の値を指定できます。

入力ウィンドウからアプリケーションの UI 要素に移動するときに、フォーカス ターゲットを指定します。
