InkOverlay.SelectionMoved Event

Occurs when the position of the current selection has changed, such as through alterations to the user interface, cut-and-paste procedures, or the Selection property.

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

public event InkOverlaySelectionMovedEventHandler SelectionMoved

The event handler receives an argument of type InkOverlaySelectionMovedEventArgs containing data about this event.

When you create an InkOverlaySelectionMovedEventHandler 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.

To get the old bounding rectangle of the Strokes collection that has been moved, use the OldSelectionBoundingRect of the InkOverlaySelectionMovedEventArgs object. To get the new bounding rectangle, call the GetBoundingBox method for the Strokes collection in the InkOverlay object's Selection property.

In this example, an SelectionMoved event handler examines a selection after it has been moved. If the selected Strokes collection is moved so that any of the selection is off the left or top side of the window, then the selection is moved back to its original position.

private void mInkObject_SelectionMoved(object sender, InkOverlaySelectionMovedEventArgs e)
    // mInkObject can be InkOverlay or InkPicture
    Rectangle newBounds = mInkObject.Selection.GetBoundingBox();

    // Check if we have gone off the left or top sides of the window. 
    if (newBounds.Left < 0 || newBounds.Top < 0)
        // Move to back to original spot
        mInkObject.Selection.Move(e.OldSelectionBoundingRect.Left - newBounds.Left,
            e.OldSelectionBoundingRect.Top - newBounds.Top);

        // Trick to insure that selection handles are updated
        mInkObject.Selection = mInkObject.Selection;
