Ink.InkDeleted Event

Článek

Occurs when a Stroke object is deleted from the Ink object.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)

Syntax

'Declaration
Public Event InkDeleted As StrokesEventHandler
'Usage
Dim instance As Ink 
Dim handler As StrokesEventHandler 

AddHandler instance.InkDeleted, handler

public event StrokesEventHandler InkDeleted

public:
 event StrokesEventHandler^ InkDeleted {
    void add (StrokesEventHandler^ value);
    void remove (StrokesEventHandler^ value);
}

JScript does not support events.

Remarks

The event handler receives an argument of type StrokesEventArgs that contains data about this event.

When you create a StrokesEventHandler delegate, you identify the method that handles the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate.

If you use the InkOverlay object or the InkPicture control (where EditingMode equals Delete and EraserMode equals StrokeErase) and pass the eraser over a stroke, you get the following sequence of events:

InkDeleted
InkAdded
InkDeleted

The additional InkAdded and InkDeleted events occur because the underlying code adds an internal, invisible stroke to track the eraser.

The InkDeleted event fires even when in select mode, not only when in delete mode. This requires that you monitor the editing mode (which you are responsible for setting) and be aware of the mode before interpreting the event. The advantage of this requirement is greater freedom to innovate on the platform through greater awareness of platform events.

Examples

In this example an InkDeleted event handler writes information about the deleted strokes to a list box control.

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());

        }
    }
}
