InvisibleApp.ShapeAdded Event (Visio)

Published: July 16, 2012

Occurs after one or more shapes are added to a document.

Version Added: Visio 4.1

Private Sub expression _ShapeAdded(ByVal Shape As [IVSHAPE])

expression A variable that represents an InvisibleApp object.

Parameters

Name

Required/Optional

Data Type

Description

Shape

Required

[IVSHAPE]

The shape or group of shapes that was added to the document.

A Shape object can serve as the source object for the ShapeAdded 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.

To determine if a ShapeAdded event was triggered by a new shape or group of shapes being added to the page, by a set of existing shapes being grouped, or by a paste action, you can use the Application.IsInScope property. If IsInScope returns True when passed visCmdObjectGroup, the ShapeAdded event was triggered by a grouping action. If IsInScope returns True when passed visCmdUFEditPaste or visCmdEditPasteSpecial, the ShapeAdded event was triggered by a paste operation. If IsInScope returns False when passed all of these arguments, the event must have been triggered by new shapes being added to the page.

If you are 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.

This VBA example shows how to count shapes added to a drawing that are based on a master called Square. Paste the code into the active document's project in Visio.

The DocumentSaved event handler runs when the active document is saved. The handler initializes an integer variable, intNumberOfSquares, which is used to store the count.

The ShapeAdded event handler runs each time a shape is added to the drawing page, whether the shape is dragged from a stencil, drawn with a drawing tool, or pasted from the Clipboard. The handler checks the Master property of the new shape and, if the shape is based on the Square master, increments intNumberOfSquares.

 
Dim intNumberOfSquares As Integer 
 
Private Sub Document_DocumentSaved(ByVal vsoDocument As Visio.IVDocument) 
 
 'Initialize number of squares added. 
 intNumberOfSquares = 0 
 
End Sub 
 
Private Sub Document_ShapeAdded(ByVal vsoShape As Visio.IVShape) 
 
 Dim vsoMaster As Visio.Master 
 
 'Get the Master property of the shape. 
 Set vsoMaster = vsoShape.Master 
 
 'Check whether the shape has a master. If not, 
 'the shape was created locally. 
 If Not (vsoMaster Is Nothing) Then 
 
 'Check whether the master is "Square". 
 If vsoMaster.Name = "Square" Then 
 
 'Increment the count for the number of squares added. 
 intNumberOfSquares = intNumberOfSquares + 1 
 
 End If 
 
 End If 
 
 MsgBox "Number of squares: " & intNumberOfSquares, vbInformation, _ 
 "Document Created Example" 
 
End Sub
