void SelectionResized([in] IInkRectangle* OldSelectionRect);

[Microsoft® Visual Basic® 6.0]

Public Event SelectionResized(OldSelectionRect As InkRectangle)

Parameters

OldSelectionRect

[in] The bounding rectangle of the selected InkStrokes collection as it existed before the SelectionResized event fired.

Note: This rectangle is specified in ink space coordinates, which allows for undo scenarios.

Remarks

This event method is defined in the _IInkOverlayEvents and _IInkPictureEvents dispatch-only interfaces (dispinterfaces) with an ID of DISPID_IOESelectionResized.

Example

[Visual Basic 6.0]

This Visual Basic 6.0 example creates an InkOverlay object and allows the user to alternately ink, select, and delete the ink by setting the EditingMode property, while reporting details on the SelectionMoved, SelectionMoving, SelectionResized, SelectionResizing, StrokesDeleted and StrokesDeleting events within a text box. This application starts with a standard .exe application and adds a reference to Microsoft Tablet PC Type Library, a Picture control, Picture1, a command button, Command1, and a text box, Text1, then adds the following code to the form.

    'the options with each click of the
    'button.

        'multiple cursors at once.
        Text1.Text = "Can't switch while collecting ink"
    ElseIf theInkOverlay.EditingMode = IOEM_Ink Then
        theInkCollector.EditingMode = IOEM_Select
