StrokesEventHandler 委派

發行項
10/29/2008

表示方法，這個方法會處理在 Ink 物件、InkOverlay 物件、InkPicture 控制項和 Strokes 集合上加入及移除 Strokes 的事件。

命名空間： Microsoft.Ink
組件： Microsoft.Ink (在 Microsoft.Ink.dll 中)

語法

'宣告
Public Delegate Sub StrokesEventHandler ( _
    sender As Object, _
    e As StrokesEventArgs _
)
'用途
Dim instance As New StrokesEventHandler(AddressOf HandlerMethod)

public delegate void StrokesEventHandler(
    Object sender,
    StrokesEventArgs e
)

public delegate void StrokesEventHandler(
    Object^ sender, 
    StrokesEventArgs^ e
)

/** @delegate */
public delegate void StrokesEventHandler(
    Object sender,
    StrokesEventArgs e
)

JScript 不支援委派。

參數

sender
型別：System.Object
這個事件的來源 Ink 物件或 Strokes 集合。

e
型別：Microsoft.Ink.StrokesEventArgs
包含事件資料的 StrokesEventArgs 物件。

備註

在建立 StrokesEventHandler 委派 (Delegate) 時，您要識別處理事件的方法。若要使事件與您的事件處理常式產生關聯，請將委派的執行個體 (Instance) 加入至事件。除非您移除委派，否則每當事件發生時就會呼叫事件處理常式。

StrokesEventHandler 委派可用來實作 InkAdded、InkDeleted、StrokesAdded 和 StrokesRemoved 事件處理常式。

範例

在這個範例中，InkAdded 事件處理常式會將已加入之筆劃的相關資訊寫入清單方塊控制項。

Private Sub Ink_InkAdded(ByVal sender As Object, ByVal e As StrokesEventArgs)
    ' since this event fires in all modes, we will check EditingMode
    ' and examine the StrokeIds only if we are currently in mode: InkOverlayEditingMode.Ink 
    If InkOverlayEditingMode.Ink = Me.mInkOverlay.EditingMode Then
        For Each id As Integer In e.StrokeIds
            Me.listBoxStrokeId.Items.Add("Added ID:" + id.ToString())
        Next
    End If
End Sub

private void Ink_InkAdded(object sender, StrokesEventArgs e)
{
    // since this event fires in all modes, we will check EditingMode
    // and examine the StrokeIds only if we are currently in mode: InkOverlayEditingMode.Ink 
    if (InkOverlayEditingMode.Ink == this.mInkOverlay.EditingMode)
    {
        foreach (int id in e.StrokeIds)
        {
            this.listBoxStrokeId.Items.Add("Added ID:" + id.ToString());

        }
    }
}

在這個範例中，InkDeleted 事件處理常式會將已刪除之筆劃的相關資訊寫入清單方塊控制項。

Private Sub Ink_InkDeleted(ByVal sender As Object, ByVal e As StrokesEventArgs)
    ' since this event fires in select mode also, we will check EditingMode
    ' and examine the StrokeIds only if we are currently in mode: InkOverlayEditingMode.Delete 
    If InkOverlayEditingMode.Delete = Me.mInkOverlay.EditingMode Then
        For Each id As Integer In e.StrokeIds
            Me.listBoxStrokeId.Items.Add("Deleted ID:" + id.ToString())
        Next
    End If
End Sub

private void Ink_InkDeleted(object sender, StrokesEventArgs e)
{
    // since this event fires in select mode also, we will check EditingMode
    // and examine the StrokeIds only if we are currently in mode: InkOverlayEditingMode.Delete 
    if (InkOverlayEditingMode.Delete == this.mInkOverlay.EditingMode)
    {
        foreach (int id in e.StrokeIds)
        {
            this.listBoxStrokeId.Items.Add("Deleted ID:" + id.ToString());

        }
    }
}
