InkInputProcessingConfiguration.RightDragAction 屬性

  • 參考

定義

命名空間:
Windows.UI.Input.Inking
編輯

取得或設定 InkPresenter 物件如何處理手寫筆筒按鈕、手寫筆橡皮擦提示、滑鼠右鍵或類似的次要輸入。

根據預設，此次要輸入會處理為主要輸入，並轉譯為 InkStroke (請參閱備註) 。

public:
 property InkInputRightDragAction RightDragAction { InkInputRightDragAction get(); void set(InkInputRightDragAction value); };
InkInputRightDragAction RightDragAction();

void RightDragAction(InkInputRightDragAction value);
public InkInputRightDragAction RightDragAction { get; set; }
var inkInputRightDragAction = inkInputProcessingConfiguration.rightDragAction;
inkInputProcessingConfiguration.rightDragAction = inkInputRightDragAction;
Public Property RightDragAction As InkInputRightDragAction

屬性值

InkInputRightDragAction

使用次要能供性修改時的輸入行為。

範例

在這裡，我們會將 RightDragAction 設定為 LeaveUnprocessed ，並宣告 UnprocessedInput 事件接聽程式進行指標輸入。

inkCanvas.InkPresenter.InputProcessingConfiguration.RightDragAction = 
  InkInputRightDragAction.LeaveUnprocessed;

inkCanvas.InkPresenter.UnprocessedInput.PointerPressed += 
  UnprocessedInput_PointerPressed;
inkCanvas.InkPresenter.UnprocessedInput.PointerMoved += 
  UnprocessedInput_PointerMoved;
inkCanvas.InkPresenter.UnprocessedInput.PointerReleased += 
  UnprocessedInput_PointerReleased;

在這裡，我們會定義指標輸入的自訂事件處理常式。 處理常式可用來實作筆墨筆劃選取。

private void UnprocessedInput_PointerPressed(InkUnprocessedInput sender, Windows.UI.Core.PointerEventArgs args)
{
  lasso = new Polyline()
  {
    Stroke = new SolidColorBrush(Windows.UI.Colors.Blue),
    StrokeThickness = 1,
    StrokeDashArray = new DoubleCollection() {5, 2},
  };

  lasso.Points.Add(args.CurrentPoint.RawPosition);

  selectionCanvas.Children.Add(lasso);
}

private void UnprocessedInput_PointerMoved(InkUnprocessedInput sender, Windows.UI.Core.PointerEventArgs args)
{
  lasso.Points.Add(args.CurrentPoint.RawPosition);
}

private void UnprocessedInput_PointerReleased(InkUnprocessedInput sender, Windows.UI.Core.PointerEventArgs args)
{
  lasso.Points.Add(args.CurrentPoint.RawPosition);

  boundingRect = inkCanvas.InkPresenter.StrokeContainer.SelectWithPolyLine(lasso.Points);

  DrawBoundingRect();
}

備註

若要將輸入當做 UnprocessedInput 傳遞至您的應用程式以進行自訂處理，請將 RightDragAction 設定為 LeaveUnprocessed。
