Assembly: Microsoft.Ink (in microsoft.ink.dll)
'Declaration Public Delegate Sub StrokesEventHandler ( _ sender As Object, _ e As StrokesEventArgs _ ) 'Usage Dim instance As New StrokesEventHandler(AddressOf HandlerMethod)
/** @delegate */ public delegate void StrokesEventHandler ( Object sender, StrokesEventArgs e )
Not applicable.
Parameters
- e
The StrokesEventArgs object that contains the event data.
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.
The StrokesEventHandler delegate is used to implement the InkAdded, InkDeleted, StrokesAdded, and StrokesRemoved event handlers.
This C# example adds an InkAdded event handler to an Ink object associated with an InkCollector object, theInkCollector. The event handler writes information about the added strokes to a list box, theListBox.
//... InkCollector theInkCollector = new InkCollector(Handle); theInkCollector.Enabled = true; // Add a handler for InkAdded Events to display // their Ids in a listbox. theInkCollector.Ink.InkAdded += new StrokesEventHandler(InkAdded_Event); //... public void InkAdded_Event(object sender, StrokesEventArgs e) { int [] theAddedStrokeIds = e.StrokeIds; theListBox.Items.Clear(); foreach (int i in theAddedStrokeIds) { theListBox.Items.Add("Added Stroke Id: " + i.ToString()); } }
This Microsoft® Visual Basic® .NET example adds an InkAdded event handler to an Ink object associated with an InkCollector object, theInkCollector. The event handler writes information about the added strokes to a list box, theListBox.
'... Dim theInkCollector As New InkCollector(Handle) theInkCollector.Enabled = true 'Add a handler for InkAdded Events to display 'their Ids in a listbox. AddHandler theInkCollector.Ink.InkAdded, AddressOf InkAdded_Event '... Public Sub InkAdded_Event(ByVal sender as Object, _ ByVal e As StrokesEventArgs) Dim theAddedStrokeIds() As Integer = e.StrokeIds theListBox.Items.Clear() Dim i As Integer For Each i In theAddedStrokeIds theListBox.Items.Add("Added Stroke Id: " & i.ToString()) Next End Sub
