Documents.SelectionAdded Event (Visio)
Published: July 16, 2012
Occurs after one or more shapes are added to a document.
A Shape object can serve as the source object for the SelectionAdded event if the shape's Type property is visTypeGroup(2) or visTypePage(1).
The SelectionAdded and ShapeAdded events are similar in that they both fire after shape(s) are created. They differ in how they behave when a single operation adds several shapes. Suppose a Paste operation creates three new shapes. The ShapeAdded event fires three times and acts on each of the three objects. The SelectionAdded event fires once, and it acts on a Selection object in which the three new shapes are selected.
If you're using Microsoft Visual Basic or Visual Basic for Applications (VBA), the syntax in this topic describes a common, efficient way to handle events.
If you want to create your own Event objects, use the Add or AddAdvise method. To create an Event object that runs an add-on, use the Add method as it applies to the EventList collection. To create an Event object that receives notification, use the AddAdvise method. To find an event code for the event you want to create, see Event codes.
You can use VBA WithEvents variables to sink the SelectionAdded event.
For performance considerations, the Document object's event set does not include the SelectionAdded event. To sink the SelectionAdded event from a Document object (and the ThisDocument object in a VBA project), you must use the AddAdvise method.
