Значение свойства

Тип: Microsoft.Ink.Cursor
The object that generated the CursorButtonUp event.

Заметки

The Microsoft.Ink.Cursor class is not to be confused with System.Windows.Forms.Cursor class. Microsoft.Ink.Cursor represents general information about a tablet pointing and selecting device, usually a pen, while System.Windows.Forms.Cursor represents the image used to paint the mouse pointer.

Примеры

The following example shows how you can subscribe to the CursorInRange event, CursorButtonDown event, and the CursorButtonUp event in order to have the ink pointer (when inking with the mouse) be displayed using a different color than the ink itself.

When the CursorInRange event fires, a check is made to see if this is the first time that the InkCollector object has come in contact with this particular Cursor object. If so, the DrawingAttributes property is assigned with a clone of the DefaultDrawingAttributes property. This ensures that subsequent access to the DrawingAttributes property does not throw a null reference exception. If the mouse is being used, the ink color is set to red.

Private Sub mInkObject_CursorInRange(ByVal sender As Object, ByVal e As InkCollectorCursorInRangeEventArgs)
    Const MOUSE_CURSOR_ID As Integer = 1
    If e.NewCursor Then
        ' mInkObject can be InkCollector, InkOverlay, or InkPicture
        e.Cursor.DrawingAttributes = mInkObject.DefaultDrawingAttributes.Clone()
        ' if this cursor is the mouse, we'll set color to red
        If (MOUSE_CURSOR_ID = e.Cursor.Id) Then
            e.Cursor.DrawingAttributes.Color = Color.Red
        End If

    End If
End Sub

private void mInkObject_CursorInRange(object sender, InkCollectorCursorInRangeEventArgs e)
{
    const int MOUSE_CURSOR_ID = 1;

    if (e.NewCursor)
    {
        // mInkObject can be InkCollector, InkOverlay, or InkPicture
        e.Cursor.DrawingAttributes = mInkObject.DefaultDrawingAttributes.Clone();
        // if this cursor is the mouse, we'll set color to red
        if (MOUSE_CURSOR_ID == e.Cursor.Id)
        {
            e.Cursor.DrawingAttributes.Color = Color.Red;
        }
    }
}

When the CursorButtonDown event fires, a check is made to see if the Cursor object supplied to the event is the mouse. If so, the Color() property is to set to blue.

Private Sub mInkObject_CursorButtonDown(ByVal sender As Object, ByVal e As InkCollectorCursorButtonDownEventArgs)
    Const MOUSE_CURSOR_ID As Integer = 1
    If (MOUSE_CURSOR_ID = e.Cursor.Id) Then
        e.Cursor.DrawingAttributes.Color = Color.Blue
    End If
End Sub

private void mInkObject_CursorButtonDown(object sender, InkCollectorCursorButtonDownEventArgs e)
{
    const int MOUSE_CURSOR_ID = 1;

    if (MOUSE_CURSOR_ID == e.Cursor.Id)
    {
        e.Cursor.DrawingAttributes.Color = Color.Blue;
    }

}

When the CursorButtonUp event fires, a check is made to see if the Cursor object supplied to the event is the mouse. If so, the Color() property is to set back to red.

Private Sub mInkObject_CursorButtonUp(ByVal sender As Object, ByVal e As InkCollectorCursorButtonUpEventArgs)
    Const MOUSE_CURSOR_ID As Integer = 1
    If (MOUSE_CURSOR_ID = e.Cursor.Id) Then
        e.Cursor.DrawingAttributes.Color = Color.Red
    End If
End Sub

private void mInkObject_CursorButtonUp(object sender, InkCollectorCursorButtonUpEventArgs e)
{
    const int MOUSE_CURSOR_ID = 1;

    if (MOUSE_CURSOR_ID == e.Cursor.Id)
    {
        e.Cursor.DrawingAttributes.Color = Color.Red;
    }
}
