InkPicture.Painting Event
Assembly: Microsoft.Ink (in microsoft.ink.dll)
'Declaration Public Event Painting As InkOverlayPaintingEventHandler 'Usage Dim instance As InkPicture Dim handler As InkOverlayPaintingEventHandler AddHandler instance.Painting, handler
/** @event */ public void add_Painting (InkOverlayPaintingEventHandler value) /** @event */ public void remove_Painting (InkOverlayPaintingEventHandler value)
In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.
The event handler receives an argument of type InkOverlayPaintingEventArgs that contains data about this event.
When you create an InkOverlayPaintingEventHandler 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. For performance reasons, the default event interest is off but is turned on automatically if you add an event handler.
This C# example invokes a Painting event handler that assigns random values to the DrawingAttributes object's Color and Width properties before the ink is painted.
[C#]
using Microsoft.Ink;
//...
theInkPicture.Painting += new InkOverlayPaintedEventHandler(theInkPicture_Painting);
//...
private void theInkPicture_Painting(object sender, InkOverlayPaintingEventArgs e)
{
DrawingAttributes theDrawingAttributes = new DrawingAttributes();
Random randomGenerator = new Random();
theDrawingAttributes.Color = Color.FromArgb(randomGenerator.Next(255),
randomGenerator.Next(255), randomGenerator.Next(255));
theDrawingAttributes.Width = randomGenerator.Next(240) + 30;
theInkPicture_Painting.Ink.Strokes.ModifyDrawingAttributes(theDrawingAttributes);
}
