Article
10/19/2012

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

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

Syntax

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

public delegate void InkOverlaySelectionResizedEventHandler(
    Object sender,
    InkOverlaySelectionResizedEventArgs e
)

public delegate void InkOverlaySelectionResizedEventHandler(
    Object^ sender, 
    InkOverlaySelectionResizedEventArgs^ e
)

JScript does not support delegates.

Parameters

sender
Type: System.Object

The source InkOverlay object of this event.

e
Type: Microsoft.Ink.InkOverlaySelectionResizedEventArgs

The InkOverlaySelectionResizedEventArgs object that contains the event data.

Remarks

The SelectionResized event occurs when the size of the current selection has changed, for example through alterations to the user interface, cut-and-paste procedures, or the Selection property.

When you create an InkOverlaySelectionResizedEventHandler 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 SelectionResized event handler examines a selection after it has been resized. If the selected Strokes collection has been resized so that either dimension is smaller than 500 HIMETRIC units, the selection is restored to its original size.

Private Sub mInkObject_SelectionResized(ByVal sender As Object, ByVal e As InkOverlaySelectionResizedEventArgs)
    Dim newBounds As Rectangle = mInkObject.Selection.GetBoundingBox()
    ' Check if we are too small 
    If (newBounds.Height < 500 Or newBounds.Width < 500) Then 
        ' Resize to back to original rectangle
        mInkObject.Selection.ScaleToRectangle(e.OldSelectionBoundingRect)

        ' Trick to insure that selection handles are updated
        mInkObject.Selection = mInkObject.Selection
    End If 
End Sub

private void mInkObject_SelectionResized(object sender, InkOverlaySelectionResizedEventArgs e)
{
    Rectangle newBounds = mInkObject.Selection.GetBoundingBox();
    // Check if we are too small 
    if (newBounds.Height < 500 || newBounds.Width < 500)
    {
        // Resize to back to original rectangle
        mInkObject.Selection.ScaleToRectangle(e.OldSelectionBoundingRect);

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