Represents the method that handles the SelectionResizing event of an InkOverlay object.

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

Syntax

'Declaration
Public Delegate Sub InkOverlaySelectionResizingEventHandler ( _
    sender As Object, _
    e As InkOverlaySelectionResizingEventArgs _
)
'Usage
Dim instance As New InkOverlaySelectionResizingEventHandler(AddressOf HandlerMethod)

public delegate void InkOverlaySelectionResizingEventHandler(
    Object sender,
    InkOverlaySelectionResizingEventArgs e
)

public delegate void InkOverlaySelectionResizingEventHandler(
    Object^ sender, 
    InkOverlaySelectionResizingEventArgs^ e
)

JScript does not support delegates.

Parameters

sender
Type: System.Object

The source InkOverlay object of this event.

e
Type: Microsoft.Ink.InkOverlaySelectionResizingEventArgs

The InkOverlaySelectionResizingEventArgs object that contains the event data.

Remarks

The SelectionResizing event occurs when the size of the current selection is about to change, such as through alterations to the user interface, cut-and-paste procedures, or the Selection property.

When you create an InkOverlaySelectionResizingEventHandler 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 in managed code but is turned on automatically if you add an event handler.

Examples

In this example, an SelectionResizing event handler examines a selection before it has been resized. If the selection will be resized so that any of it is outside the bounds of the window, the event handler turns the selection red by changing the Color property of each selected Stroke object.

Private Sub mInkObject_SelectionResizing(ByVal sender As Object, ByVal e As InkOverlaySelectionResizingEventArgs)
    If e.NewPixelRect.Left < 0 Or e.NewPixelRect.Top < 0 Or _
       e.NewPixelRect.Right > mInkObject.AttachedControl.ClientRectangle.Width Or _
       e.NewPixelRect.Bottom > mInkObject.AttachedControl.ClientRectangle.Height Then 

        For Each stroke As Stroke In mInkObject.Selection
            ' change the stroke color
            stroke.DrawingAttributes.Color = Color.Red
        Next 

    End If 
End Sub

private void mInkObject_SelectionResizing(object sender, InkOverlaySelectionResizingEventArgs e)
{
    if (e.NewPixelRect.Left < 0 || e.NewPixelRect.Top < 0 ||
        e.NewPixelRect.Right > mInkObject.AttachedControl.ClientRectangle.Width ||
        e.NewPixelRect.Bottom > mInkObject.AttachedControl.ClientRectangle.Height)
    {
        foreach (Stroke stroke in mInkObject.Selection)
        {
            // change the stroke color
            stroke.DrawingAttributes.Color = Color.Red;
        }
    }

}
